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, Im not sure well be able to recognize all those traces yet, will we...

 

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

 

 

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!
