and the result of applying that code to the contests for 2005. See also
the comments at the end of that post. I would be delighted if anyone
who spots any errors in the script would inform me.<br />
<br />
We
can also look at the results for periods of ten years at a time; the
only difference in the way that these decadal tables are
calculated is that the minimum number of rQSOs is raised from 50 to 250
for tables pertaining to all QSOs and from 25 to 125 for those
pertaining to intra-W QSOs. (That is, <a href="https://github.com/N7DR/contest-statistics/blob/master/count-rnils.py">the value of the variable MIN_QSOs</a> is changed from 50 to 250.) <br />
<br />
Here are the results for 2023 and for the period from 2014 to 2023. As in prior years, I refrain from comment on specific calls.<br />

Throughout this post, I apply the procedures developed in the second post above.<br />
<br />
For the purpose of this post, only <i>verified</i> QSOs are counted.<br />
<br />
<h3 style="text-align: left;">
Lowest Probability </h3><p>
I begin with an ordered list of the stations with the lowest probabilities
of busting a call in 2023 CQ WW SSB.</p>

At first, I
thought that it might be due to people logging calls mis-spotted on the
various spotting networks. But its presence when one limits the analysis
to running stations would seem to make that theory untenable. Perhaps
it is due to an increase in entrants using code readers, although one
would expect few runners to be using those. So this might be an
interesting area for further analysis, should anyone be interested. It
really is a quite remarkable year-on-year change. <br /><p></p><p></p><p></p><p></p><p></p><p>I
think it's also interesting to see who appears to have the lowest
probability of busting a call over an extended period. So, for the last
ten years:</p>

In tables of reverse busts, one sometimes
finds what seems like an unreasonable number of reverse busts (as is the
case, for example, for UT3NK in the 2023 CW table above). This is
generally caused by a discrepancy
between the call actually sent by the listed station and the one
recorded as being sent in at least some QSOs in the station's log. Other causes of frequent reverse busts are poor sending/audio, unusual calls and calls that are very similar to the call of an active, well-known contester.</p><p>Looking at a ten-year period:</p>

<br />
</p><h3>
Continent Pairs </h3>
<br />
We start by looking at the number of QSOs for pairs of continents from the contests for 2022.<br />
<br />
The procedure is simple. We consider only QSOs that meet the following criteria:<br />
<ol><li>marked as "two-way" QSOs (<i>i.e.</i>, both parties submitted a log containing the QSO);</li><li>no callsign or zone is bust by either party.</li></ol><p>
A counter is maintained for every possible pair of continents and the pertinent counter is incremented
once for each distinct QSO between stations in those continents.<br />
<br />
Separate
figures are provided below for each band, led by a figure integrating
QSOs on all bands. The figures are constructed in such a way as to show
the results for both the SSB and CW contests on a single figure. (Any
pair of continents with no QSOs that meet the above criteria appears in
black on the
figures.) Note the logarithmic scale.<br /></p><p></p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEh_Icnzi-kq84gwym2JBOq9dQJ5XvMMRIIofyAdi0atMNLD1le7SH4R-TiaGlkwUvMESXsHJl5rbHOceTz8fB0yHK4PRLM-VGlQQUmsFDUu45qJS2heGDogiOMfISDgZ7JF13SUYG4SYNW0nOxz2tu8dv_d8Z19sOoxGLM1D74tpxmecW94jUXDwssAQmQ/s800/QSOs-per-cp-2023-ALL.png" style="margin-left: 1em;

Continents and Distance</h3><p>
<br />
Below is a series of figures showing the distribution of distance for QSOs as a
function of continent.<br />
<br />
Each
plot shows a colour-coded distribution of the distance of QSOs for each
continent, with the data for SSB appearing above the data for CW within
each continent.<br />
<br />
For every half-QSO in a given continent, the distance
of the QSO is calculated; in this way, the total number of half-QSOs
in
bins of width 500 km is accumulated. Once all the QSOs for a particular
mode have been binned in this manner, the distribution for each
continent
is normalised to total 100% and the result coded by colour and plotted.
The mean distance for each continent and mode is denoted by a small
white
rectangle added to the underlying distance distribution. The 99%
confidence range of the value of mean is marked by a small blue
rectangle (typically entirely subsumed by the white rectangle). The
median is marked with a vertical brown rectangle.<br />
<br />
As
usual, only QSOs for which logs have been provided by both parties, and
which show no bust of either callsign or zone number are included. Bins
coloured black are those for which no QSOs are present at the relevant
distance.<br />
<br />
The
resulting plots are reproduced below. The difference between EU and the other continents is stark.<br /></p><p></p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjlpJX-D3fW5kvMcG658t5-_YqQK87vtELZk8W6s_73KwsSsGi9DpUfdaPFJ8OvE7mviL138rmS5AG84Ou1jLNazuGx5WuZrbTt4i4C4VcUXPSwJxa97saeUmx5rEfYRFObFB4B6UeSskr73p5AqJPJdw5LtJEtUbKUMEKmybnmEuX_2xW__PAcOjd7ciE/s800/continent-distance-2023-ALL.png" style="margin-left: 1em;

</h3><p>
<br />
A simple way to display the activity in the CQ WW contests
is to count the number of half-QSOs in each continent (a single QSO
contains two half-QSOs, so a single QSO may contain two different
continents or the same continent twice). We count half QSOs, making sure
to include each valid QSO
only once (that is, if the same QSO appears in two submitted logs, it is
counted only once).<br />
<br />
If we do this for the entire contest without taking the individual bands into account, we obtain this figure:</p><p> </p><p></p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiu3BYR52sOmW1ZC7cBoOc27jjKXBRpxkHGK-rU8HIcU31yekiajgdDFm8ErNqnMmtzozvyebQJGGBNyhMElF39sdQXq5CTqxrjbYwHVdks4ODIIYN1dNfDkicfGR0n__afCMTaprdL6tteLAi6OoNPy01rBZDyk2KdwZtPsqZSeKARgwLoTSNvjcvr-xs/s800/continent-half-qsos-ALL.png" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="600" data-original-width="800" height="480" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiu3BYR52sOmW1ZC7cBoOc27jjKXBRpxkHGK-rU8HIcU31yekiajgdDFm8ErNqnMmtzozvyebQJGGBNyhMElF39sdQXq5CTqxrjbYwHVdks4ODIIYN1dNfDkicfGR0n__afCMTaprdL6tteLAi6OoNPy01rBZDyk2KdwZtPsqZSeKARgwLoTSNvjcvr-xs/w640-h480/continent-half-qsos-ALL.png" width="640" /></a></div><p></p><p>The plot shows data for both SSB and CW contests over the period from

between two European stations. </p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhfyliPElZkjQhwZEwkfbCyWmzoP3dQ_uzs9HyG_7hHkRak_ueQ_ByjG15q4KsfeohMQ5dwi4Opu4IcHqVNXuBAhxVz5o1CFDBm5RwFtYl3simgJrF5mFBpRn7tjR9JHUTXoxSfsVO1WNrG8Jz_2sJiF5FbzTYDD2CAPjkl1d_GEQbQarClzBHlcwwyJj4/s800/intra-continent-10.png" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="600" data-original-width="800" height="480" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhfyliPElZkjQhwZEwkfbCyWmzoP3dQ_uzs9HyG_7hHkRak_ueQ_ByjG15q4KsfeohMQ5dwi4Opu4IcHqVNXuBAhxVz5o1CFDBm5RwFtYl3simgJrF5mFBpRn7tjR9JHUTXoxSfsVO1WNrG8Jz_2sJiF5FbzTYDD2CAPjkl1d_GEQbQarClzBHlcwwyJj4/w640-h480/intra-continent-10.png" width="640" /></a></div><br /><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEizwgH22DePIcc_hav7Z7xrH1SZ1wQodB_64P1U0_tpM9SyVegB1nW72lLBzxaqUyC2p1YxSA4iLHDodtsFVGt4hRbdPlv5Ey8jOmGP7jlLnXVSQitbs2Zavc-xezpxC3vixTivYn5vNpd8lnAYKBC3qxWgebr4ARLq1g4wic60cJFtNGP8UM-W0R2iiEU/s800/intra-continent-15.png" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="600" data-original-width="800" height="480" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEizwgH22DePIcc_hav7Z7xrH1SZ1wQodB_64P1U0_tpM9SyVegB1nW72lLBzxaqUyC2p1YxSA4iLHDodtsFVGt4hRbdPlv5Ey8jOmGP7jlLnXVSQitbs2Zavc-xezpxC3vixTivYn5vNpd8lnAYKBC3qxWgebr4ARLq1g4wic60cJFtNGP8UM-W0R2iiEU/w640-h480/intra-continent-15.png" width="640" /></a></div><br /><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgg03P_9kRmV4IlrRDjZ9SwknHKT4xe69Qoc9f9XkSd89nc_VcRKsAX2LTe1abCxMowP4vf49DRbqEoiBRSYAQiiKW7lXaywEYbLFvoAl4ZPYBTZscPKLwa449bF0QZ7M5_hNViVk0lq39DZrycHxwXeaBf6s5al65V6JMmBt1JgIZ37I5-pPs7pVIZwBQ/s800/intra-continent-20.png" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="600" data-original-width="800" height="480" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgg03P_9kRmV4IlrRDjZ9SwknHKT4xe69Qoc9f9XkSd89nc_VcRKsAX2LTe1abCxMowP4vf49DRbqEoiBRSYAQiiKW7lXaywEYbLFvoAl4ZPYBTZscPKLwa449bF0QZ7M5_hNViVk0lq39DZrycHxwXeaBf6s5al65V6JMmBt1JgIZ37I5-pPs7pVIZwBQ/w640-h480/intra-continent-20.png" width="640" /></a></div><br /><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiC1g0thCOzudopFheXbXk2Qguj8z_FyYWsd6tNLiUv0Z9sLR26wP3W9ADHVviQlAjP2uCFFICD1qogerWnOu4woGogF75-8gMrNwLchJKMq7qp2Lvw6JsuJi6O6E0pls6R3rnhjVPx69J3Q3h8jLx9ocLAEplVHZrTTvKqD0DrBlc5UrNYE2y-Wy4X1Vk/s800/intra-continent-40.png" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="600" data-original-width="800" height="480" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiC1g0thCOzudopFheXbXk2Qguj8z_FyYWsd6tNLiUv0Z9sLR26wP3W9ADHVviQlAjP2uCFFICD1qogerWnOu4woGogF75-8gMrNwLchJKMq7qp2Lvw6JsuJi6O6E0pls6R3rnhjVPx69J3Q3h8jLx9ocLAEplVHZrTTvKqD0DrBlc5UrNYE2y-Wy4X1Vk/w640-h480/intra-continent-40.png" width="640" /></a></div><br /><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiW1iDCEPD6szBU1xSgokipEG75hs2H0p1jvMvf20IlUSIB210hHRf6grby5ZX5wubZJO3ckAp96hBHg3o23cBjwScoU_q4ueEHsH5JGlaOuCtCAQErrOilzC6lUcBXYOXXYu4sS3NBQSTM-iDB-LxdkTKLAPkhhNC8HLIIDZsxMSEfaTR4j0hii_Im7Xg/s800/intra-continent-80.png" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="600" data-original-width="800" height="480" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiW1iDCEPD6szBU1xSgokipEG75hs2H0p1jvMvf20IlUSIB210hHRf6grby5ZX5wubZJO3ckAp96hBHg3o23cBjwScoU_q4ueEHsH5JGlaOuCtCAQErrOilzC6lUcBXYOXXYu4sS3NBQSTM-iDB-LxdkTKLAPkhhNC8HLIIDZsxMSEfaTR4j0hii_Im7Xg/w640-h480/intra-continent-80.png" width="640" /></a></div><br /><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgXn46bcFfG98ov7x_BIKPPOfR5TU3xh7vBZm0Uv8HkJ5k61nnMjSmvl3TgeLOicGNG3I701exPvTxTAijMa4alTfczXSPhpyYUhQHEgzdmjQFmH8PhbkPy8V1pIpn9HlMZorjRKA85qw_sKqa2DNREbXGg6dSd4r3cic1L_ZJMYhfchTgDJW8SC9Sc76c/s800/intra-continent-160.png" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="600" data-original-width="800" height="480" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgXn46bcFfG98ov7x_BIKPPOfR5TU3xh7vBZm0Uv8HkJ5k61nnMjSmvl3TgeLOicGNG3I701exPvTxTAijMa4alTfczXSPhpyYUhQHEgzdmjQFmH8PhbkPy8V1pIpn9HlMZorjRKA85qw_sKqa2DNREbXGg6dSd4r3cic1L_ZJMYhfchTgDJW8SC9Sc76c/w640-h480/intra-continent-160.png" width="640" /></a></div><br /><p>Flogging
a dead horse as I do every year, on 160m 60% of QSOs in this "world wide

DX-friendly mode. On SSB, about four fifths of all QSOs were between
two

Ukraine (and the last-minute decision of the CQ WW committee to permit

<span style="font-family: inherit;">As
usual, there follow a few analyses that interest me. There is, of
course, plenty of scope to use the augmented files for further analys<span style="font-family: inherit;">e</span>s.</span><br />
<br />
<span style="font-family: inherit;">Below are some simple zone-based analyses from the logs. </span><br />
<br />
</p><h3 class="post-title entry-title" itemprop="name">
Zones and Distance
</h3><p>
<br />
As in prior years, we can examine the distribution of distance for QSOs as a function of zone.<br />
<br />
Below is a series of figures showing this distribution integrated over all bands and, separately, band by band for the <a href="https://cqww.com/">CQ WW SSB and CQ WW CW</a> contests for 2023.<br />
<br />
Each
plot shows a colour-coded distribution of the distance of QSOs for each
zone, with the data for SSB appearing above the data for CW within each
zone.<br />
<br />
For every half-QSO in a given zone, the distance
of the QSO is calculated; in ths way, the total number of half-QSOs in
bins of width 500 km is accumulated. Once all the QSOs for a particular
contest have been binned in this manner, the distribution for each zone
is normalised to total 100% and the result coded by colour and plotted.
The mean distance for each zone and mode is denoted by a small white
rectangle added to the underlying distance distribution.<br />
<br />
Only QSOs for which logs have been provided by both parties, and
which show no bust of either callsign or zone number are included. Bins
coloured black are those for which no QSOs are present at the relevant
distance.<br />
<br />
The
resulting plots are reproduced below. I find that they display in a
compact format a wealth of data that is informative and often
unexpected.</p><p></p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhy9en7Wx0GmZSc0IFD7MpOMbQBUcE2oDx69DSJOYBXa7OgWtq6V7dJMtjnS1JN5Hax_d-jsKNRdBWO1fm0komXKQrbWtp0H_UJ7IJ7hvH63ofz9KSGGcTBip8nCV2iwlb_mFVEON6uiz4OXuTAPjWnvmco1-Q9Od9FU2bN2QiZ_Dtm5VAKBg2Dsqc2I8w/s800/distance-2023-ALL.png" style="margin-left: 1em;

The procedure is simple. We consider only QSOs that meet the following criteria:<br />
<ol><li>marked as "two-way" QSOs (<i>i.e.</i>, both parties submitted a log containing the QSO);</li><li>no callsign or zone is bust by either party.</li></ol><p>
A counter is maintained for every pair of zones (<i>i.e.</i>,
1-1, 1-2, 1-3 ... 40-39, 40-40) and the pertinent counter is incremented
once for each distinct QSO between stations in those zones.<br />
<br />
Separate
figures are provided for each band, led by a figure integrating
QSOs on all bands. The figures are constructed in such a way as to show
the results for both the SSB and CW contests on a single figure. (Any zone
pair with no QSOs that meet the above criteria appears in black on the
figures.)<br />
<br />
It is clear from these figures, as from those
for earlier years, that CQ
WW is principally a contest for intra-EU QSOs, and secondarily one for
QSOs between EU and the East Coast of North America. This format is
undoubtedly popular, as CQ WW, in
both its SSB and CW incarnations, would seem by any reasonable measure to be the
most popular contest of the year. But one does wonder whether there
isn't some other format that would more strongly encourage participation from
other parts of the world, instead of concentrating activity in these limited
areas.</p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjT1qFcugSWUkPTzrncTVTxlkpdubAygRtVHs-rZ7qAq3SKB7R8yqzTaT8E2jVAkaWCo-ymymtSWLMHaA4E3LiM-CuvawAVketdyZsLrrcwQgM-r1J0myzcQMmSzWlKd3aSiRQzAnVux-9SCTfDO_3iAkAXSt7Vz2JOnqIfuAfWpfbRdDB36qXpWvXIvzM/s800/QSOs-per-zp-2023-ALL.png" imageanchor="1" style="margin-left: 1em;

The activity between pairs of zones in the CW and SSB CQ WW contests
over the period from 2005 to 2023 may be usefully summarised in a single
figure:</p><p></p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEga6ddW6Y3V2TvIJ_CNWFmaMoL58IL_rV4Aphqh169jTKIKMpA_QG-ZPLy6lC2uAX-3J6y43r7piDQNqMCaPat6KQzwiGf75gwtKm9jzJ152YivoyHIDtzHNrKL72kVAMDoFqpZJzCD0DjWgFrr4tHyb7QYnyMhpORMOHNcpS4cePEXnOREH6G0bwwftVQ/s800/non-zero-pairs.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="600" data-original-width="800" height="480" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEga6ddW6Y3V2TvIJ_CNWFmaMoL58IL_rV4Aphqh169jTKIKMpA_QG-ZPLy6lC2uAX-3J6y43r7piDQNqMCaPat6KQzwiGf75gwtKm9jzJ152YivoyHIDtzHNrKL72kVAMDoFqpZJzCD0DjWgFrr4tHyb7QYnyMhpORMOHNcpS4cePEXnOREH6G0bwwftVQ/w640-h480/non-zero-pairs.png" width="640" /></a></div><br /><p></p><p></p><p></p>
There are 820 possible zone pairs: (z1, z1), (z1, z2) ... (z1, z40),
(z2, z2), (z2, z3) ... (z39, z39), (z39, z40), (z40, z40). The above
figure shows the number of different zone pairs actually present in the
public logs, for each mode and for each year for which data are
available, separated on a band-by-band basis and presented in the form
of percentages of the maximum possible count (<i>i.e., </i>820).<br />
<br />
The top two lines require some additional explication: the line marked
"MEAN" is the arithmetic mean of the results for the six separate bands
for the relevant year and mode. The line marked "ANY" is also
constructed from the data for the individual bands, but such that any
give zone pair need be present on any one (or more, of course) of the
individual bands to be included on the "ANY" line.<br />

Half-QSOs Per Zone for CQ WW CW and SSB, 2005 to 2022

A simple way to display the activity in the CQ WW contests
is to count the number of half-QSOs in each zone. Each valid QSO
requires the exchange of two zones, so we simply count the total number
of times that each zone appears, making sure to include each valid QSO
only once.<br />
<br />
If we do this for the entire contest without taking the individual bands into account, we obtain this figure:</div><div class="post-body entry-content" id="post-body-2315458881817215500" itemprop="description articleBody"><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhGVa3TX_7WCRmFckl_v7BPa35osY6hPaEA2gLQjlfM3wdV-NImFQxWRDxzYbP2rPkHQ9LbL4Y1HTErL2nmtFdGtsrJTAtKGrhev0LE6jJl-4fowSfh1PrLynntbazMZulIX7vDJHOcrF_1OCvx86K0sSqTOfQUDx53c3x86qgl15HU-BypfdL43v38RA0/s800/half-qsos-ALL.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="600" data-original-width="800" height="480" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhGVa3TX_7WCRmFckl_v7BPa35osY6hPaEA2gLQjlfM3wdV-NImFQxWRDxzYbP2rPkHQ9LbL4Y1HTErL2nmtFdGtsrJTAtKGrhev0LE6jJl-4fowSfh1PrLynntbazMZulIX7vDJHOcrF_1OCvx86K0sSqTOfQUDx53c3x86qgl15HU-BypfdL43v38RA0/w640-h480/half-qsos-ALL.png" width="640" /></a></div></div><div class="post-body entry-content" id="post-body-2315458881817215500" itemprop="description articleBody">

The plot shows data for both SSB and CW contests over the period from 2005 to 2023 (each year has a rectangle for SSB on the left, and a rectangle for CW on the right). As in <a href="http://drevans.blog.enginehousebooks.com/2023/03/zone-based-analyses-from-2022-cq-ww-ssb.html">earlier posts</a>,
I include only QSOs for which both parties submitted a log and neither
party bust either the zone or the call of the other party. The black rectangles represent contests in which no half-QSOs were made from (or
to) a particular zone. By far the most striking feature of this plot is
the way in which activity in EU overwhelms that in the rest of the world.

<br />
<span style="font-family: inherit;">As in prior years, there follow a few basic
analyses that interest me. There is, of course, plenty of scope to use
the log files for further analys<span style="font-family: inherit;">e</span>s, some of which are suggested by the figures below.</span><br />
<br />
<span style="font-family: inherit;">Below
are some simple analyses of
basic statistics from the logs. The 2023 versions of the contests showed a more-or-less full return to normal operation, following several years disrupted by COVID and the invasion of Ukraine by Russia. The latter, of course, is still under way, but its effect on the contest seems to be decreasing. And we finally had sunspots (Well, I assume we did for the SSB leg -- I was away for that contest; conditions in the CW leg were certainly an improvement). </span><br />
</p><h3>
</h3>
<h3>
Number of Logs</h3><p>Until 2020, the raw number of submitted logs for SSB had been
relatively
flat for
several years; the logs submitted for CW showed a fairly
steady annual increase. In 2020, unsurprisingly, the number of logs in
both modes increased to new record, probably because of the pandemic; CQ
WW SSB 2021 set another record;
on CW, the number of logs decreased slightly, but would still have been a
record were it not for 2020. 2022 was another year of unusual
circumstances: not only was the pandemic still in evidence in much of
the world, but the Russian invasion of Ukraine, along with the CQ WW
committee's vacillation on how to proceed in light of that invasion --
and then the protest against <a href="https://cqww.com/blog/updated-cq-contest-policy-relating-to-russias-invasion-of-ukraine/">the committee's position as of the contest dates</a> -- was always going to lead to a reduction in the number of submitted logs. In 2023, the numbers for both modes bounced back up somewhat, but they both still fell short of being a record, especially on CW.</p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEg3SC2oQKcEH7YNTyptBCd393bXDRpwy6wSXa9-7nsst3XOfjGfC-s-ZlBn_mO_V3HnWxQ6BH3LrTmbPEAWXm2LS5jtUZ-TU-G1pQOI4Kv_uKnkkCupZlCfq4aiagLcOQysm-QV9yi1zbrdkC-_yE4zYeAfuiX-2vVyRNH8jbI3D5SCi1BRSvzQNWSVXFQ/s800/cq-ww-nlogs.png" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="600" data-original-width="800" height="480" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEg3SC2oQKcEH7YNTyptBCd393bXDRpwy6wSXa9-7nsst3XOfjGfC-s-ZlBn_mO_V3HnWxQ6BH3LrTmbPEAWXm2LS5jtUZ-TU-G1pQOI4Kv_uKnkkCupZlCfq4aiagLcOQysm-QV9yi1zbrdkC-_yE4zYeAfuiX-2vVyRNH8jbI3D5SCi1BRSvzQNWSVXFQ/w640-h480/cq-ww-nlogs.png" width="640" /></a></div><p></p><p></p><p>One
not infrequently reads statements to the effect that the popularity
of contests such as CQ WW has long been increasing. This plot suggests
that this claim had not been true for a number of years prior to 2020
(and
even when it was
true, there are alternative explanations for the year-on-year increase,
such as increasing ease of electronic log submission). The circumstances
for 2020, 2021 and 2022 have been so unusual that it would seem to be
an error to regard them as in any way indicative of a trend. But 2023 does give some cause for hope that on SSB numbers have reached a new, higher plateau; CW seems to have reverted to the level of just before 2020.</p><p><br />
</p><h3>
<span style="font-family: inherit;">Popularity</span></h3><p>
<span style="font-family: inherit;">By definition, <i>popularity</i> requires some measure of <i>people</i> (or, in our case, the simple proxy of callsigns) -- there is no reason to believe, <i>a priori</i>,
that the number of received logs as shown above is related in any
particular way to the popularity of a contest, despite rather frequent
conclusory statements to the contrary.</span><br />
<br />
<span style="font-family: inherit;">So we look at the number of calls in
the logs as a function of time, rather than positing any kind of
well-defined positively correlated relationship between log submission
and popularity (actually, the posts I have seen don't even bother to
posit such a relationship: they are silent on the matter, thereby simply
seeming to presume that the reader will assume one). </span><br />
<br />
<span style="font-family: inherit;">However, the situation isn't as
simple as it might be, because of the presence of busted calls in logs.
If a call appears in the logs just once (or some small number of times),
it is more likely to be a bust rather an actual participant. Where to
set a cut-off <i>a priori</i> in order to discriminate between busts and
actual calls is unclear; but we can plot the results of choosing
several such values. </span><br />
<br />
<span style="font-family: inherit;">First, for SSB:</span></p><p><span style="font-family: inherit;"></span></p><div class="separator" style="clear: both; text-align: center;"><span style="font-family: inherit;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjAb2KFYr_ve4yWH2n9hSxIgNRsithMIAnKHZUUEerFzMlCczVEzSu4BPVza4QOb4caE7vaU3oDwKwULMzKMnLi-M9-sVB15MIzUXf7LFCQBjCHKRe-2xWYpqYwy-ThWl8VswPTlLBM0NIEk95Mpw7QIBN7dIKbct2kIyB4fXgp4fLPGJIkKZ6H1DOj6UI/s800/cq-ww-ssb-ncalls.png" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="600" data-original-width="800" height="480" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjAb2KFYr_ve4yWH2n9hSxIgNRsithMIAnKHZUUEerFzMlCczVEzSu4BPVza4QOb4caE7vaU3oDwKwULMzKMnLi-M9-sVB15MIzUXf7LFCQBjCHKRe-2xWYpqYwy-ThWl8VswPTlLBM0NIEk95Mpw7QIBN7dIKbct2kIyB4fXgp4fLPGJIkKZ6H1DOj6UI/w640-h480/cq-ww-ssb-ncalls.png" width="640" /></a></span></div><p></p><p></p><p></p><p><span style="font-family: inherit;">Regardless
of how many logs a call
has to appear in before we regard it as a legitimate callsign, the
popularity of CQ WW SSB during the pandemic surely
increased from the doldrums of the prior few years. Complicating the picture in the past couple of years is, of course, the reduction in participation that is (presumably)
due to the Russian invasion of Ukraine. Whatever the cause, the number of calls certainly seems to be well down on the number at a similar point in the last solar cycle</span><br /></p><p>
<span style="font-family: inherit;"><br /></span>
<span style="font-family: inherit;">[I
note that a plausible argument
can be made that the number of uniques will be more or less proportional
to the number of QSOs made (I have not tested that hypothesis; I leave
it as an exercise for the interested reader to determine whether it is
true), but there is no obvious reason why the same would be true for,
for example, callsigns that appear in, say, ten or more logs. The
interested reader might also consider basing a similar analysis on
eXtended Super Check Partial files as created by the <a href="https://github.com/N7DR/drscp">drscp program</a>.]</span><br />

CW, we see that in 2022 the reduction due (presumably) to the Russian

lowest of all the years for which data are available. In 2023 there was a slight correction, but the numbers are still well short of the numbers during the high-sunspot years of the last solar cycle.<br /></p><p> </p>

<span style="font-family: inherit;">Geographical Participation</span></h3><p>

<span style="font-family: inherit;">How has the geographical distribution of entries changed over time?</span><br />

The number of logs submitted from zone
28 continues to show an increased level.
Still, the number of
logs from

<h3>
Running and Calling</h3><p>
<br />
On SSB, the ongoing gradual shift towards stations strongly favouring
either running or calling, rather than splitting their effort between
the two types of operation, finally appears to have reached some kind of
equilibrium. There was essentially no change between 2018 and 2019, and
even a (very) slight reversal of the trend in 2020 and 2021. 2022,
however, for the first time saw more than 30% of entrants making no run
QSOs at all, a situation that continued in 2023. In 2023, the number of stations making fewer than 10% of their QSOs in a run exceeded 60%.<br /></p><p></p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgL5HJjjeD9sivquN4gH5UccyWKgqf2C1dwPVv_di6S6SNUx_xl2lR8o0SelBOXDJHtbj8uvzukZ7RP41LJ1NuO73dN9iV68fQo08In7931DJFcyFEdr0adYnqLF2HiVl0MgzN21lvmXyWaBzQN7l8pNoOBbDk35JnYjK8rURY7H5_lOh3RrtraI0dvOJQ/s800/ssb-run-qsos-2005--2023.png" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="600" data-original-width="800" height="480" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgL5HJjjeD9sivquN4gH5UccyWKgqf2C1dwPVv_di6S6SNUx_xl2lR8o0SelBOXDJHtbj8uvzukZ7RP41LJ1NuO73dN9iV68fQo08In7931DJFcyFEdr0adYnqLF2HiVl0MgzN21lvmXyWaBzQN7l8pNoOBbDk35JnYjK8rURY7H5_lOh3RrtraI0dvOJQ/w640-h480/ssb-run-qsos-2005--2023.png" width="640" /></a></div><br /><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEg2B47WZM-7fjIo8i7gFgQkSOe_pjOVTTfdVUSDqMz7pf7bI-eh7fvsFwCT8Uf08bJmU-HOKnaxwghaic9bXP2C6s01xFDVMOnTEQqWhIUtcIQ4OEPrTrbHh9zafxzJBo4FU1pYVBl5EU1BvJz-2qY4gyo-d6-f2s2AvGBc6otT58d5RNWKNiLDMV3Vgeo/s800/ssb-run-qsos-per-year-2005--2023.png" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="600" data-original-width="800" height="480" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEg2B47WZM-7fjIo8i7gFgQkSOe_pjOVTTfdVUSDqMz7pf7bI-eh7fvsFwCT8Uf08bJmU-HOKnaxwghaic9bXP2C6s01xFDVMOnTEQqWhIUtcIQ4OEPrTrbHh9zafxzJBo4FU1pYVBl5EU1BvJz-2qY4gyo-d6-f2s2AvGBc6otT58d5RNWKNiLDMV3Vgeo/w640-h480/ssb-run-qsos-per-year-2005--2023.png" width="640" /></a></div><br /><p></p><p></p><p></p><p></p><p></p><p>I have not investigated the cause of the decrease in the
percentage of stations strongly favouring running, although the public
logs could readily be used to distinguish possibilities that spring to
mind, such as more SO2R operation, more multi-operator stations, and/or a
reluctance of stations to forego the perceived advantages of spots from
cluster networks. In any case, it certainly seems that SSB operators seem to fall decisively into one of two camps: runners and callers (look at the quite astonishing bimodal distribution in the first of the two graphs above, with the vast majority nearly always calling other stations).<br />
<br />
On CW, the split between callers and runners continues to be much less
bimodal than on SSB (as mentioned above, on SSB, fully 30% of entrants have <i>no</i>
run QSOs; on CW, the equivalent number is below 10%). Indeed, the
difference in call/run behaviour on the two modes (and the difference in
the way that the behaviour has changed over time) is profound, and
probably worthy of further investigation. CW continues to appear to exhibit
what would seem to be a much healthier split between the two operating
styles:</p><p></p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEj2EWtKEVbzRoy-Lq1eqWgW4mnE-8ogXDCuiZp5Teug5ocS_Hdc8cz647aZNCGfoxOJdRVnjgHejcrLlmsXk2KPSZ2FyZmB-06GP3LntWXMzaaZtswoBrZqCPvZOEeDYyuwr5c8COzcEQHZVG5Rq5QXusDNvyP2-vNlwwEqQlL-qxZVOux6LsB6zSP7xqE/s800/cw-run-qsos-2005--2023.png" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="600" data-original-width="800" height="480" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEj2EWtKEVbzRoy-Lq1eqWgW4mnE-8ogXDCuiZp5Teug5ocS_Hdc8cz647aZNCGfoxOJdRVnjgHejcrLlmsXk2KPSZ2FyZmB-06GP3LntWXMzaaZtswoBrZqCPvZOEeDYyuwr5c8COzcEQHZVG5Rq5QXusDNvyP2-vNlwwEqQlL-qxZVOux6LsB6zSP7xqE/w640-h480/cw-run-qsos-2005--2023.png" width="640" /></a></div><br /><p></p><p></p> <div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjDX8KIeo_RqU_vlkzn2YWqV32o-WqfLj5NFvCzti8SebnoAwXckYY6KNusKbpZR8MocutZUNrIGQddeqXzy5QW9f7KOkTxnhKbU8oWJ0w6iMHzj9D3wCtH7823xA7l95awFGMdK8O_vNyTCSwL_x78kxRa2Hf6GPChlO-mSJxpEE2CAqSys7lMOugmikk/s800/cw-run-qsos-per-year-2005--2023.png" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="600" data-original-width="800" height="480" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjDX8KIeo_RqU_vlkzn2YWqV32o-WqfLj5NFvCzti8SebnoAwXckYY6KNusKbpZR8MocutZUNrIGQddeqXzy5QW9f7KOkTxnhKbU8oWJ0w6iMHzj9D3wCtH7823xA7l95awFGMdK8O_vNyTCSwL_x78kxRa2Hf6GPChlO-mSJxpEE2CAqSys7lMOugmikk/w640-h480/cw-run-qsos-per-year-2005--2023.png" width="640" /></a></div><br /><br /><p></p><p>

<h3>
Assisted and Unassisted</h3><p>
<br />
We can see how the relative popularity of the assisted and unassisted categories has changed since they were introduced:</p><p></p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgMvUeU950b0zUhgHqW0cO1YkpnRe_mGuqI30DEGpL2W47b4s_nUyDoxXtEI7L5_yzydakVNXkitxb2IJJjOCHhDEa1VPuHLHQ162_-0cIC87BGDaG_T74Yu8WvPjeWDe_AEaNFCtCKTmn7DXyDuxK79vOBX9-jamEXW3VpswsY6Oo6u-f5GjwNY84QVtM/s800/cq-ww-qso-nlogs-a-u.png" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="600" data-original-width="800" height="480" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgMvUeU950b0zUhgHqW0cO1YkpnRe_mGuqI30DEGpL2W47b4s_nUyDoxXtEI7L5_yzydakVNXkitxb2IJJjOCHhDEa1VPuHLHQ162_-0cIC87BGDaG_T74Yu8WvPjeWDe_AEaNFCtCKTmn7DXyDuxK79vOBX9-jamEXW3VpswsY6Oo6u-f5GjwNY84QVtM/w640-h480/cq-ww-qso-nlogs-a-u.png" width="640" /></a></div><br /> <p></p><p></p><p></p><p></p><p></p><p>On CW, there continue to be more or less equal numbers of assisted and unassisted
logs, although a gap in favour of assisted operation slowly seems to be opening. On SSB the unassisted logs handily exceeds the number of
assisted logs. My guess, for what it's worth, is that CW assistance is
more widespread partly because it (partially) absolves stations from
actually being able to copy at high speed, and partly because the RBN is
so effective that essentially <i>all</i> CQing stations are spotted.<br />
<br />
I find it particularly interesting that the number of CWU logs has
remained essentially unchanged ever since the unassisted category was
created.<br />
<br />
Looking at the number of QSOs appearing in the unassisted and assisted logs:</p><p></p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjo6kBpfsdJP9GU03KDn76idaskU6o1pi7I2Y2mm78n8KOAH7pXlqHXwehv4ygVraOy7U1L12XWlpg8SluYQVnF-04T2NsYH8UrSpQXdyUqfO8NaucY1E5o1ubwPcVKScKFGaphf04GVLkZn41JLLjZ6dUPtkzmrzW4j_xtWPkD4AbMOaVVPLIrswkf63E/s800/cq-ww-qso-percentiles.png" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="600" data-original-width="800" height="480" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjo6kBpfsdJP9GU03KDn76idaskU6o1pi7I2Y2mm78n8KOAH7pXlqHXwehv4ygVraOy7U1L12XWlpg8SluYQVnF-04T2NsYH8UrSpQXdyUqfO8NaucY1E5o1ubwPcVKScKFGaphf04GVLkZn41JLLjZ6dUPtkzmrzW4j_xtWPkD4AbMOaVVPLIrswkf63E/w640-h480/cq-ww-qso-percentiles.png" width="640" /></a></div><br /> <p></p><p></p><p></p><p>(The lines are for the median number of logs; the vertical bars run from
10% to 90%, 20% to 80%, 30% to 70%, 40% to 60%, with opacity increasing
in that order.)</p><p><br />
A long-term downward trend in the numbers of QSOs in the assisted logs
ceased in 2016, and since then the median number of QSOs in the
assisted logs has remained essentially unchanged. A more or less
constant difference of roughly one hundred QSOs between
the median CW and SSB logs (in favour of CW) continues.<br />

Inter-Zone QSOs</h3><p>

We can show the number of inter-zone
QSOs, both band-by-band and in total. In these plots, the number of QSOs
is accumulated every ten minutes, so there are six points per hour.</p><p></p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEg5hxjOouvNSy3rsw-JCHFXUKeqxT6Xfidtu2XOOsOsLKD46NusUtlo6AIGVjz3IiMNZ_SWduNgy4juSxLrciR1n1g5f8ZT6KDcT62hHrAKmXpoZYmT5nesKbAQiq9ud2HOYvkBeeKHW44ohcEWqxIDTbMc6pVRM5Qu13tztmvaUgcdYHE6QRofKBwiHFY/s800/activity-10.png" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="600" data-original-width="800" height="480" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEg5hxjOouvNSy3rsw-JCHFXUKeqxT6Xfidtu2XOOsOsLKD46NusUtlo6AIGVjz3IiMNZ_SWduNgy4juSxLrciR1n1g5f8ZT6KDcT62hHrAKmXpoZYmT5nesKbAQiq9ud2HOYvkBeeKHW44ohcEWqxIDTbMc6pVRM5Qu13tztmvaUgcdYHE6QRofKBwiHFY/w640-h480/activity-10.png" width="640" /></a></div><p></p><p></p><p></p><p></p><p>The new cycle has definitely started.

not cooperate to the same extent as it did on SSB.</p><p></p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhKfVz1Z8pW62HFDL0GLs0_9euTTESPPLDQDcoPyWK-jnuZUuasgusUW0WCpCSazka3LENx3O1B_F5x2NChsLLjFpjClzva3v94rjCkDo0DPCvD7C7rGY2JNawrMjD7-47e3Qa21vlaOQcdci0nQg0RWebHoQ7-AK5nbht3E5KUNYR-zNy1wJkgQRbMKUU/s800/activity-20.png" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="600" data-original-width="800" height="480" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhKfVz1Z8pW62HFDL0GLs0_9euTTESPPLDQDcoPyWK-jnuZUuasgusUW0WCpCSazka3LENx3O1B_F5x2NChsLLjFpjClzva3v94rjCkDo0DPCvD7C7rGY2JNawrMjD7-47e3Qa21vlaOQcdci0nQg0RWebHoQ7-AK5nbht3E5KUNYR-zNy1wJkgQRbMKUU/w640-h480/activity-20.png" width="640" /></a></div><p></p><p>Much

The first column in the table is the callsign. The
second column is the total number of times that the call appears in
logs. That is, for example, if a station worked ZF1A on six bands, that will
increment the value in the second column of the ZF1A row by six. The
third column is the percentage of logs that contain the callsign at
least once.<br />

<br />
<br />
Links to the cleaned and augmented logs may be found in <a href="https://www.adrive.com/public/Ws5CQw/cq-ww">this directory</a> (look for "clean" or "augmented" in the filenames).<br />
<br />
The cleaned logs are the result of processing the <i>QSO:</i>
lines from the entrants' submitted Cabrillo files to ensure that all
fields contain valid values and all the data match the format required
in the rules. Any line containing illegal data in a field (for example, a
zone number greater than 40, or a date/time stamp that is outside the
contest period) has simply been removed. Also, only the <i>QSO:</i>
lines are retained, so that each line in the file can be processed
easily. All zones are rendered with two digits, so as to further
simplify processing by scripts or programs.<br />
<br />
The augmented logs
contain the same information as the cleaned logs, but with the addition
of
some useful (derived) information on each line. In addition to the
actual logs, two additional sources of information are used when
appropriate:<br />
<br />
</p><ol><li>AD1C has made accessible <a href="http://www.country-files.com/">historical cty.dat and associated files</a>. These allow us to use callsign-based multiplier lists as they would have existed at the time of each contest.<br />
<br />
</li><li>
From 2009 onwards, the <a href="http://reversebeacon.net/">Reverse Beacon Network</a>
(RBN) has been available for the CW contests. This allows us to include
the time since a station was last posted by the RBN (see below for
details).</li></ol>
<br />
The information added to each line of the augmented logs comprises: <br />
<ol><li><span style="font-family: inherit;">A sequence of four characters that are the same for each entry in a particular log:</span></li><ul><li><span style="font-family: inherit;"> a. </span><span style="font-family: inherit;"><span style="font-family: inherit;">letter "A" or "U" indicating "assisted" or "unassisted"</span> </span></li><li><span style="font-family: inherit;"> b. letter "Q", "L", "H" or "U", indicating respectively QRP, low power, high power or unknown power level</span></li><li><span style="font-family: inherit;"> </span><span style="font-family: inherit;">c.

the "C" category ] </span></li><li><span style="font-family: inherit;"> </span><span style="font-family: inherit;">d. character "1", "2", "+" or "U", indicating respectively that the number of transmitters is one, two, unlimited or unknown</span></li></ul><li><span style="font-family: inherit;">A four-digit number representing

<h3>
RBN Information</h3>
<br />
In the CW contests from 2009 onwards,
the RBN was active, automatically spotting the frequency at which any
station calling CQ was transmitting. To reflect possible use of RBN
information, the augmented files now include a fourteenth flag. For
the sake of uniformity, this column is present in all the augmented
files, regardless of whether the RBN actually contributed useful
information to a particular contest.<br />
<br />
Each QSO has one of several characters in the fourteenth column of flags. These characters should be interpreted as follows:<br />
<br />
'-'<br />
No useful RBN-derived information is available for this QSO.<br />
<br />
'0'<br />
The worked station (<i>i.e</i>., the second call on the log line) appears to have begun to CQ on this frequency within (roughly) 60 seconds prior to the QSO.<br />
<br />
'A' to 'Z'<br />
For the <i>n</i>th letter of the alphabet: the worked station appears to have been CQing on this frequency for (roughly) <i>n</i> minutes prior to the QSO.<br />
<br />
'+'<br />
The worked station appears to have been CQing for more than 26 minutes on this frequency.<br />
<br />
'<'<br />
Because the the RBN is distributed, and because each contest entrant
station has its own clock, there is generally a skew between the reading
of the clock of the station making the QSO and the timestamp from the
RBN at which it believes a posting was made (indeed, it's unclear from
the RBN's [lack of] documentation exactly how the timestamp on an
individual RBN posting is to be interpreted). If the character '<'
appears in the the RBN column, it indicates that the raw values of the
clocks suggest that the QSO took place up to two minutes <i>before</i>
the RBN reported the worked station commencing to CQ at this frequency.
When this occurs, the most likely interpretation is that there is
non-negligible skew between the two clocks, and the station was actually
worked almost as soon as a CQ was posted by the RBN. This character also appears if the RBN erroneously posts the <i>worked</i> station as CQing at this frequency shortly after the QSO. But it might also
mean that the entrant was simply lucky and found the CQing station just
as it fired up on a new frequency. <br />
<br />
Notes:<br />
<ul><li>The encoding of some of the flags requires subjective
decisions to be made as to whether the flag should be true or false;
consequently, and because CQ has yet to understand the importance of
making their scoring code public, the value of a flag for a specific QSO
line in some circumstances might not match the value that CQ would
assign. (Also, CQ has more data available in the form of check logs,
which are generally not made public.)</li><li>I made no attempt to deduce or infer the run status of a QSO in
the second party's log (if such exists), regardless of the status in the
first party's log. This allows one cleanly to perform correct
statistical analyses anent the number of QSOs made by running stations
merely by excluding QSOs marked with a <i>U</i> in column k.</li><li>No attempt is made to detect the case in which both participants of a
QSO bust the other station's call. This is a problematic situation
because of the relatively high probability of a false positive unless
both stations accurately log the frequency as opposed to merely the
band. (Also, on bands
on which split-frequency QSOs are common, the absence of both transmit
and receive frequency is a problem; I confess that I have never
understood why Cabrillo was not designed to report both transmit and
receive frequencies -- or even to define clearly <i>which</i> frequency is to be reported. I digress.) Because of the likelihood of false
positives, it seems better, given the presumed rarity of double-bust
QSOs, that no attempt be made to mark them.</li><li>The entries for the zones in the case of zone or reverse zone busts are normalised to two-digit values.</li></ul>D. R.

The videos are created
with time steps of ten minutes; when playing the video, each time step is displayed for five seconds. The videos
are presented as animated GIF files, so they should display correctly
without any specialised video software installed on your computer.<br />
<br />
The videos assume that all communication is via the great-circle
short path route, and include only inter-zone contacts. The width of the arcs is an absolute measure of
the number of QSOs taking place over that path in the particular
10-minute segment. The colour of the arc reflects the relative number of
QSOs taking place over the path. Each separate image (<i>i.e.</i>, 10-minute
segment) is normalized so that the path with the greatest number of
QSOs is rendered in white. Paths with fewer QSOs are in progressively
darker colours. Thus, arc colour should not be compared from one still image to
another; arc width, however, is meaningful. The width of an arc in
pixels is one plus the natural logarithm of the number of QSOs
represented by the arc<span style="font-family: "courier new" , "courier" , monospace;">. <br /></span></p>D. R.

The QSO took place on 2023-09-25 at 1353z, while Ante was operating as VC3K/VE2 in the SKCC <a href="https://www.skccgroup.com/ve9skcc/ve9skcc.php">Canadian Straight Key Month event</a>. Normally, 10m is yet to open here at that time, but VA2BBW was a solid S5 here in Colorado, while he gave me an honest 599.</p><p>I believe that the QSO was enabled by a burst of auroral activity; the aurora was probably being modulated by the North American electric grid at 60Hz; as we can see from <a href="https://www.adrive.com/public/fsmDsa/spectrum.png">this spectrum plot</a> (taken from the elongated dah in the "d" of "de") the raspy buzz is clearly due to 60Hz modulation.</p><p>This is the first time I have heard such a manifestation; normally, auroral QSOs that I have heard display distinct widening of the signal, along with blurring of the individual CW elements as different parts of the auroral region move around at different speeds.</p><p>Or to sum it all up in three words: radio is magic.</p><p><br /></p>D.
