The KX3 (and K3) bandwidth controls are with respect too the audio
frequency, not the RF frequency. So in LSB mode, for example, the
bandwidths move in opposite directions on the KX3 and PX3. In AM mode,
the bandwidth is mirrored about the carrier frequency.
I think you're right about this but also I think that the lo/hi-cut
settings affect the audio and not the "IF" bandwidth.
I know that in the Perseus software you can influence both AM sidebands
independently and in fact listen to only one sideband plus carrier in
both AM and AM-sync and probably you would like to have that option as
well in the KX3... The only way I can get this option is by using the
KX3's I/Q output, a PC and HDSDR-software. HDSDR toggles in AM-sync
between LSB, USB and DSB with a simple click on the AM-Sync button.
