Reino, this is where we disagree, as my point is if the vfo frequency
changes, then the 'radio frequency' which I consider the same also changes.
Adrian,
Reino is right, and you are wrong. Nothing personal, just scientific
fact. The frequency readout of virtually all modern transceivers set to
receive CW is radio frequency corresponding to the center of the receive
bandwidth. When a second RX set to receive CW is tuned to peak your FT8
signal, that readout IS the center of the 50 Hz signal you are
transmitting. If your USB dial frequency is 21.074 MHz (21,074 kHz) and
your offset is 1.5 kHz, the center of your signal is 25 Hz above 21.0755
MHz (21,075.5 kHz) (25 Hz because WSJT-X defines TX frequency as the
frequency of the lowest tone).
