[amsat-bb] KPC TNC and wisp. Conflict, or I missed something.!!

[Mark L. Hammond]

Hello Nadar,

Two quick thoughts---

1--the IC-910 (and IC-9100...) are very sensitive to input levels.  If your
audio "in" to the radio it too high, the radio will not transmit.

2--if your TNC is not putting itself into KISS mode, you'll have to figure
out another way. I thought you could specify KPC-9612 as the TNC type under
TNC settings.  Please double check that.   Otherwise, you may have to put
your TNC into KISS mode and leave it there.

Or maybe it's something else?  Wire issue?
