### Augmented QSO information from CQ WW contest files from 2008 to 2014

Earlier this month I made available cleaned versions of the QSOs from the CQ WW CW and SSB public logs from 2008 to 2014.

Now I have added an augmented version of these QSOs.

Each QSO line now includes an additional four columns, with the following meanings:
1. The letter "A" or "U" indicating "assisted" or "unassisted"
2. A four-digit number representing the time if the contact in minutes measured from the start of the contest. (I realise that this can be calculated from the other information on the line, but it saves a lot of time to have the number readily available in the file without having to calculate it each time.)
3. Band
4. A set of eight flags, each encoded as T/F:
• a. QSO is confirmed by a log from the second party
• b. QSO is a reverse bust (i.e., the second party appears to have bust the call of the first party)
• c. QSO is an ordinary bust (i.e., the first party appears to have bust the call of the second party)
• d. the call of the second party is unique
• e. QSO appears to be a NIL
• f. QSO is with a station that did not send in a log, but who did make 20 or more QSOs in the contest
• g. QSO appears to be a country mult
• h. QSO appears to be a zone mult
The resulting QSOs are in a single compressed (xz) file downloadable from:
