To work as many stations as possible in the allotted time using 6 PSK mode variants.



QRP (max power 5 watts output)

Low Power (max power 25 watts output)

Medium Power (max power 50 watts output)



1st Saturday through 1st Sunday in April.

Choose any 6 hour block between:

1st Saturday in April 1000UTC <--> 1st Sunday in April 0359UTC

You may operate whenever you feel your greatest chances of successful QSOs may be! 

For scoring, your six hour block will begin with the hour that you select on the scorer page and continue for the next 6 hours.



For all participants: State/Province/DXCC Entity

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'


20 meters only!. Work each station once.

All contacts must be 2-way

No repeater, cross-mode or cross-band contacts allowed.



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.

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.



Use no more than the stated maximum for your entry category. Please keep your power output set to a reasonable level to avoid QRMing others. Use the MINIMUM power necessary to make the contact at all times!




 QSO points - Each contact counts one (1) QSO point, dupes count (0) points.

Contacts counted once per PSK mode variant

For example, N9AVY contacts N5SLY as follows:

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

N9AVY and N5SLY can count 3 QSO points for these contacts.

Multipliers - Each different state/province/country (SPC) worked. Use current ARRL DXCC list for country reference.

Final Score = (Total QSO Points) x (Multipliers).


Scoring Notes:

SPC Definition: S = U.S. States, P = Canadian Provinces, C = DXCC Countries


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, W9SMR 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

W9SMR can count a total of 50 multipliers for these contacts.
