Recently, the programs for digital modes have been enriched by the achievements of K1JT with FT8 / WSJT-X, as well as the derivatives made on this suport (JTDX, MSHV). This was followed by FT4 which allows a higher rate of connections over a period of time.WWFF operators have also joined these new possibilities. They have been hit by limits on the length of messages sent, which cannot support any combination of numbers and letters.
There are a number of 7 common variants that can be used:
TX1 (His_call) {Own_call} Own_locator
TX2 (His_call) (Own_call) (report)
TX3 (His_call) (Own_call) R (report)
TX4 (His_call) (Own_call) RR73 or RRR
TX5 (His_call) (Own_call) 73
TX6 CQ (Own_call) Own_locator
TX7 free with 13 signs (letters or numbers, including pauses)
The question is how we can transmit the information required for the WWFF, namely:
1 – how to call stations interested in WWFF
2 – how to inform about your own WWFF reference number
The first, FF can be added to the previous TX6
TX6 CQ FF (Own_call) Own_locator
where “FF” stands for “Fauna & Flora”
For information on its own reference number TX5 could be used as follows:
TX5 XXFF-0000 73 or TU
This text can be used on TX7 too
They can be accessed also from the F1 … F7 keys.
Another way to make the presence known in the band, and implicitly the WWFF reference number, is to announce our presence through a DX Cluster. But this implies the possibility of having access to a DX Cluster, both the activator and the hunter.
I would dare to recommend using FT4 which is faster and under normal conditions there is no difference in efficiency compared to FT8.
It is also considered beneficial to define dedicated frequencies for WWFF. These could be 2 kHz below the current frequencies agreed in different bands (example instead of 7074 kHz in 40m, to be at 7042 kHz for WWFF, aso)
This is a proposal. If you have other ideas, please come up with suggestions
