    We are using a Baycom USCC card with DF9IC modem with
    a T7F radio. It works ok, but since the radio is not squelched
    there is a high number of rx interrupts and error rx packets.

    Also, some bad packets seems to slip through. Much garbage is
    seen in the mheard list.

    Is this normal? Is there a way to workaround this?

    The sccstat returns (for instance):
    speed : 9600 baud
    txdelay : 5
    persist : 64
    slottime : 8
    txtail : 8
    fulldup : 0
    waittime : 2
    mintime : 3 sec
    maxkeyup : 7 sec
    idletime : 3 sec
    maxdefer : 120 sec
    group : 0x00
    txoff : off
    softdcd : off
