Hello K7DMJ,
Welcome to the world of HF!? It's probably less of a matter of the
band being dead but the propagation on then band taking your
signals to other parts of the planet where there aren't any 10m
iGates.? The other factor here is that 300bps AFSK packet isn't a
very robust mode.? You will need to have quite a bit of patience,
do a lot retries, change frequencies throughout the day to best
match propagation, etc to maximize your chances.? If both stations
support FX.25 (Direwolf does enable reception by default but
doesn't transmit it by default), it can help quite a bit but FX25
is relatively new and it's not exactly clear how many HF stations
have adopted it.?
Alternatively, there is the SCS Robust Packet protocol which is
substantially more robust than 300bps AFSK packet but other than
using an SCS hardware TNC, the only other implementation I'm aware
of isn't fully operational (
and ).

I don't know about robust packet. Pretty sure Direwolf defaults to
FX.25 protocol. Anyway, after I got packets through to an i-gate
in WI from my QTH in UT earlier this morning, I haven't had
anything else decoded, nor have I decoded anything. Pretty
disappointing. I don't think the band conditions are THAT bad
today.
