This is a Python script to parse an ADIF log file and calculate the score for the Long Island CW Club Challenge (see https://licwchallenge.org for more details)
When making a LICW Challenge contact, there is a minimum set of information that the participants must exchange, but not all of this information is supported by standard ADIF log fields.
I wanted to be able to use my normal logging program to log my Challenge QSOs and the simplest solution found was to add the extra information in the QSO note/comment field in a simple and structured way so that this program could then reliably find and extract it in order to calculate the score.
This special text can be in addition to any other notes you enter for a QSO, can be at any position in the note field and is case insensitive.
The minimum format of this special text string is:
LICW[SPC:1234xx]
Where:
- SPC = 2 or 3 character state/province/country code
- 1234 = the LICW membership number received from the other station
- xx = optional one or more bonus letters received from the other station
The special text string may be extended to support additional special bonus points, by adding an optional third section containing a comma separated list of bonus conditions:
LICW[SPC:1234xx:EXTRA1,EXTRA2,...]
Where the extra fields can be one or more of:
- FIRST - for working a station on their first ever CW QSO
- F2F - for making a QSO from a face to face meeting
- 2xF2F - for making a QSO with face to face meetings at each end
The remaining data for calculating scores is obtained from the normal QSO ADIF records.
The program will ignore all QSO records in the ADIF file that do not contain the special LICW[] field in the QSO notes.
The challenge scoring program is a command line script requiring Python 3 with its default libraries; there should be no need to install anything extra.
On Linux/MacOS:
./challenge_score.py <adif log file name>
Or on Windows:
python challenge_score.py <adif log file name>
The program can optionally filter QSOs by challenge quarter, so that it can be given a large ADIF file and just score the quarter of interest. You can either chose the current quarter or specify which quarter you require, e.g:
Process score for the current quarter:
./challenge_score.py -q now all_qsos.adif
Or for the second quarter 2023:
./challenge_score.py -q 2:23 all_qsos.adif

Total of 16 QSOs with 6 unique SPCs
Total score = 58
Q: I worked G0POT on 40m and then later a second time when he was a special station. Do I need to go back in my log and remove the first contacts LICW[] data?
A: No, the program handles duplicates contacts on any given band and it will automatically select the QSO with the highest score. So just log all LICW Challenge QSOs you make.
Not essential, but possibly nice to have:
- Only allow QSOs on valid bands
- Support for VBand QSOs? How would this be done?
