Report preparation

  • I used the AI-assisted bug report tool (Help → Support → File an Issue)
  • I have attached a support bundle or log file

What happened?

Both versions 8.7 and 8.8 work the same. Running Ubuntu 24.04 local compile and appimage versions work the same. Selected 2 meter transverter FM mode 144.390 APRS frequency signals come across normally. Switch to DFM and select a different filter size the band pass filter moves in frequency with the left edge of the filter at the selected frequency not centered on the selected frequency as is normal.
Also noticed that when selecting DFM filters larger than 12 khz do not show an increase in size (width)

What did you expect?

Expected the DFM filters to stay centered on the selected frequency and filter size to increase/decrease according to the filter selection appears amximum filter size is 11.9 khz. Hardware is a Flex 6600M using Q5 Signal transverters VHF/UHF.

Steps to reproduce

1.Connect to radio
2 Select transverter by changing antenna selection to xvtrA or B
3 Set mode to FM
3. Enter desired frequency (APRS 144.390 used)
4. Select DFM mode
5. Select different filter size while in DFM mode
