Hi, this is the behaviour I have detected with latest version in RTTY using FLDIGI. hope this could be a simple fix.
N1mm: last release, 1.0.7342.0
Radio mode: RTTY (LSB)
Radio VFO: 21085.48 MHzFldigi waterfall frequency (center after align): 21083.28 MHz, this is correct according to sweet spot of 2200 Hz
Frequency in bandmap and in n1mm main window is not correct with RTTY (lsb mode).
