To have a contest where participants get to play with PSK variants.
An excellent warm-up for the TARA Skirmish multi-mode contest.
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
Use PSK variants in the following 5 families –
· BPSK 10*/31/63[Narrow bandwidth except for BPSK63]
· QPSK 31/63* [Narrow bandwidth except for QPSK63]
· PSK/Hellschreiber [105*] [Wide bandwidth]
· PSK/FEC 31* [Wide bandwidth]
· PSK/AM 10*/31*: [Narrow bandwidth]
Note that the family definitions have been changed since last year.
Modes marked with an asterisk can be found in the free MultiPSK software package from F6CTE.
See the following website:
Thanks to Patrick, F6CTE, for expanding the PSK universe!
20 Meters only
- normal PSK sub-band for narrow modes,
- sub-band 14072.5 -14080 KHz suggested for wide bandwidth modes.
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.
For 070 Members – State/Province/DXCC Entity + 070 member number
For Non-070 - 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 PSK 31, indicating which mode will follow.
I mean, I’m not sure we’ll be able to recognize all those traces yet, will we...
‘CQ CQ PSK 31 Flavors de Your Call - switching to <Mode> k’
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 BPSK31
- Once in QPSK63
- 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!
Multipliers: 1 multiplier for each State/Province/DXCC Entity
1 additional multiplier for each different PSK family used – maximum of 5
Note that the mode multiplier has been added since last year.
Total Score: QSO Points X Multipliers
