Re: Tx frequency selection for FT8 on BITX40 running Allard's sketch #bitx40

Within WSJT-X, you pick the transmit and receive frequencies, via the WSJT UI.? These are audio frequencies in your passband, not RF frequencies. 73, Gerry W1VE On Thu, Apr 19, 2018 at 10:55 AM, Doug W <dougwilner@...> wrote: First off, thank you both for the replies.? Secondly, if my response came across as harsh that was not the intention.? I think we are now splitting hairs on common practice vs best practice.? Right from K1JT himself in the WSJT-X user manual "To avoid QRM from competing callers, it is frequently desirable to answer a CQ on a different frequency from that of the CQing station. Choose a Tx frequency that appears to be not in use."? I realize for a manually controlled rig it wouldn't be practical to change the Tx frequency every time in a fast action digital mode but wouldn't it make sense to operate in split mode with an arbitrarily selected offset above 7.074.000 but still within 3kHz to reduce noise right at x.xxx.000? |
