[Alexandria Radio Club Reflector] 3Y0K approach to deliberate QRM

[Ian]

3Y0K has an interesting strategy if deliberate QRM gets bad - they "may"
shift to S&P simplex if QRM gets bad. They will try to work you on your
frequency. See the latest communication from the team below.

3Y0K Bouvet Island DQRM strategy This strategy may only be implemented if
the DQRM is very bad and slows down our QSO rate significantly. Normal
CW/SSB pileup handling is listening UP 1 kHZ on CW and 5 kHz on SSB. DQRM
strategy is to work simplex on all bands within a 20 kHz bandwidth for CW
and 30 kHz for SSB. We will work simplex or “contest mode” within the 20
kHz window in CW. For example, operate SIMPLEX between 14010 and 14030 kHz.
In DQRM mode - we do S&P within a specified window like in any contest. All
stations are calling SIMPLEX. 3YØK tunes across the simplex window and
works stations SIMPLEX. DQRM simplex windows Band CW (kHz) SSB 80m
