Thanks to Patrick, F6CTE, for expanding the PSK universe!
Frequencies:
20 Meters only
- normal PSK sub-band for
narrow modes,
- sub-band 14072.5 -14080

Some of the contest modes are relatively wide. The PSK families chosen for the contest are either
the same width as BPSK31 or wider like BPSK63.
Please allow sufficient room between your signals and those of your fellow PSK explorers.
Certainly give plenty of room to civilians in the accepted PSK and RTTY sub-bands.

‘CQ CQ PSK 31 Flavors de Your Call - switching to <Mode> k’
Score:
Calculate claimed scores as
follows --
QSO Points: 1
point per station contacted
Contacts
counted once per PSK family
For example, K8IJ contacts N3DQU as follows:

- Once in PSK/Hell
K8IJ and N3DQU can count 3 QSO points for these contacts
The wise contester
will use as many PSK families as possible!
