6. Multi-operator Stations
A. Multi-operator single transmitter stations are only allowed one transmitted signal on air at any time.
If you are using three transceivers to scan the bands, simultaneous transmission will reclassify you as
Multi Transmitter(Category F.) – your responsibility to stop multiple transmitters operating.
B. Multi-operator Multi Transmitter stations
a. Are only allowed maximum one transmitted signal per band,
b. Simultaneous transmissions on different bands are permitted.
* Multi-operator stations are mixed mode only.
A. Suggested Call: “CQ TT”, “CQ Contest”, or “CQ Test”
B. Exchange: A valid exchange consists of RS(T) followed by a three figure serial number starting at 001 for each band.
C. No cross band contacts are allowed.
D. Exchange of contact information via satellites, telephones, repeaters, Echolink, IRLP, or the internet is not in the spirit of the contest and is banned.
All contacts are worth one point – Add the number of contacts made in the two hours and multiply by the different prefixes worked on each band in that two hours.
NB external territories count as one prefix – eg VK0 counts as VK0 and not the separate DXCC same as for VK9
e.g. 160 80 40 total contacts 50 X 35prefixes (total of each band added) = 1750 points per hour
Final Score is the addition of each two Hour 3 two hour blocks starting at 08:00
Logs are due in within one week of closure of the contest.
