To have a contest where participants get to play with PSK variants.



The Contest will have three separate entry categories - single-op club station entries are welcome in any category:

QRP: Maximum power not exceeding 5 watts
Low: Maximum power not exceeding 25 watts
Medium: Maximum power not exceeding 50 watts



Use the following 6 PSK mode variants -

  • BPSK 31 [Narrow bandwidth]
  • QPSK 31 [Narrow bandwidth]
  • BPSK 63 [Wide bandwidth]
  • QPSK 63 [Wide bandwidth]
  • BPSK 125 [Very wide bandwidth]
  • QPSK 125 [Very wide bandwidth]

These mode variants are available in most popular digital software, i.e. WinWarbler, HRD/DM780, FLDigi, etc.



20 Meters only

- normal PSK sub-band for narrow mode variants,

- sub-band 14072.5 - 14080 kHz suggested for wide bandwidth mode variants.

Some of the contest mode variants are relatively wide. 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.



For Ø7Ø Members – State/Province/DXCC Entity + Ø7Ø member number

For Non-Ø7Ø Members - State/Province/DXCC Entity + First Name

Member Number or First Name should appear in the Received Exchange ("SRX") field of your log. It will be accepted in the comment or remark field as well.


Suggested Contest Call:

'CQ CQ PSK 31 Flavors de Your Call k'

It may be useful to call CQ in BPSK 31, indicating which mode variant will follow:

'CQ CQ PSK 31 Flavors de Your Call - switching to <Mode Variant> k'



Calculate claimed scores as follows --

QSO Points: 1 point per station contacted

Contacts counted once per PSK mode variant

For example, AK4MK contacts KJ4IZW as follows:

  • Once in BPSK 31
  • Once in QPSK 63
  • Once in BPSK 125

KJ4IZW and AK4MK can count 3 QSO points for these contacts


Multipliers: 1 multiplier for each State/Province/DXCC Entity in each mode variant

Count the number of US States, Canadian Provinces and DXCC countries (S/P/Cs) worked in each mode variant.

KH6 and KL7 count both as states and as separate DXCC entities. Be sure to count US and Canada as DXCC entities.


For example, KE4JB makes the following contacts:

  • 25 States/Provinces/DXCCs in BPSK 31
  • 15 States/Provinces/DXCCs in BPSK 63
  • 10 States/Provinces/DXCCs in QPSK 31

KE4JB can count a total of 50 multipliers for these contacts.


Total Score: QSO Points X Multipliers

The wise contester will use as many PSK mode variants as possible!
