Question

Waterfall filter indicator incorrect when in FSK mode

RafalLukawiecki opened this issue 2 years ago · comments

I have noticed that the filter indicator seems to be away from the centre frequency when operating in FSK mode. This does NOT always happen, usually when changing bands or modes. It is as if the calculation for the location of the filter switched between using the MARK frequency and the frequency of MARK with the usual LSB offset. See screenshot below. The Tx and Rx point to the correct frequency, but the filter marker is off by over 2 kHz lower down.

Perhaps this may help: the issue happens when switching bands. The fix is to change mode on the radio from FSK to CW and then back to FSK. At that point the width of the filter passband returns to where it should be.

@RafalLukawiecki I believe I've managed to track this one down - thank you for the clue! It is committed to main and develop, and will be included in the next release as well.
