Can the DFM mode be adjusted to 40 KHz? This is needed for NOAA 15,18,19 137 MHz satellites

Options

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
