Why:
To have a contest where
participants get to play with PSK variants.
The PSK 31 Flavors Contest
is an excellent warm-up for the TARA Skirmish multi-mode contest.
Categories:
The Contest will have three separate
entry categories -
QRP: Maximum
power not exceeding 5 watts
Low: Maximum
power not exceeding 20 watts
Medium: Maximum
power not exceeding 100 watts
Modes:
Use the following 5 PSK mode
variants –
·
BPSK 31 [Narrow bandwidth]
·
QPSK 31 [Narrow bandwidth]
·
BPSK 63 [Wide bandwidth]
·
QPSK 63 [Wide bandwidth]
·
BPSK 125 [Very wide bandwidth]
Note that the permitted mode definitions have been changed since last year.
These mode variants are available in popular software and can be found in the free MultiPSK software package from F6CTE.
See the following website:
Thanks to Patrick, F6CTE, for expanding the PSK universe!
Frequencies:
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.
Exchange:
For 070 Members – State/Province/DXCC Entity + 070 member number
For Non-070 Members -- State/Province/DXCC Entity + Name
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.
I mean, I’m not sure we’ll be able to recognize all those traces yet, will we...

Score:
Calculate claimed scores as
follows --
QSO Points: 1
point per station contacted
Contacts
counted once per PSK mode variant
For example, K8IJ contacts N3DQU as follows:
- Once in BPSK 31
- Once in QPSK 63
- Once in BPSK 125
K8IJ and N3DQU 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, K8IJ 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
K8IJ 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!
