Can DFM bandwidth be expanded to 40 KHz for NOAA 137 MHz satellites. Would be nice on the 6700.

    No. You are stuck at 10khz.

    With DFM I can get to 24KHz wide on receive.

    Ops... I missed the DFM part.

    I think it is 20khz, at least that is as far as the Maestro would go.

    On the 6700 I could stretch it out to 24. Some folks might want Broadcast FM. Maybe more than a simple software change.

    Question: when setting DFM up the band width list is what. Is it deviation BW or Audio BW? It is probably deviation BW, just need clarification. I also saw in another posting that the audio BW is

    0-5500 Hz. Is this correct? Winlink asks for at least 6khz for full 9600 bps data rate. Your help would be appreciated. Trying to clarify.

    thanks
