2013 31 FLAVORS CONTEST
Phase Shifting where no contest has Phase Shifted before!
Saturday, 06 April 2013 from 12:00-18:00 your local time [not Universal Time]. This is a rolling start across the globe that should give opportunity to all who play.
All licensed radio amateurs. Look for Ø7Ø Club members in the event. Learn about this esteemed association on its web page: www.podxs070.com
To have a contest where participants get to play with PSK variants. The PSK 31 Flavors Contest is an exciting 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 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]
These mode variants are available in popular software such as MixW and the free MultiPSK, DM780 and FLDigi software packages. See the following websites:
Digital Master 780 - Part of the Ham Radio Deluxe Suite:
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 + 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...
'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, 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!
