Mode AFSK A normal LSB. I assumed that if by using the ALT function and consequently switching to TX DATA REV that the sideband was switched from LSB to USB.
It is.
It looks like keying is reversed but shifted in frequency on the waterfall by one keying shift value eg 170Hz. However, whilst in data mode selection the sideband indicator does change from LSB to USB using ALT.
The MARK frequency in the K3 does not change - it's still 2125. That results in a displayed SPACE frequency. Wayne/Lyle, you probably want to offset MARK by Shift when in AFSK REV (and maybe FSK REV). Remember, MARK is always the higher RF frequency so the tones have to be exchanged in AFSK REV and both mark/direction of the shift changed in FSK REV. 73, ...

Guru's, Trying to get a handle on a problem with frequency reporting in MMTTY. Not an operational issue, I just don't take any notice of MMTTY frequencies. In AFSK A mode they are incorrect. The following has become apparent, albeit undocumented. Mode AFSK A normal LSB. I assumed that if by using the ALT function and consequently switching to TX DATA REV that the sideband was switched from LSB to USB. Apparently not the case. It looks like keying is reversed but shifted in frequency on the waterfall by one keying shift value eg 170Hz.

Can anyone confirm or deny this observation and is this the way it is intended to function?
