Yes.  You seem to be at the raw AX.25 level which should work fine but
a different than what I am doing with the APRS mode on the TH-D72A.

I *could* switch it to PACKET12 mode and just use the TNC but I'd like
to get this to work with just the APRS mode.

My PATH right now is set to "ARISS" which I think is sufficient.
Please, please someone chime in and correct me if I'm wrong.

Right understood,  I just want to confirm.  Clearly raw UI frames will
work if the payload follows APRS.

To get on that damn ariss.net map!  That's all I'm asking here!

Alright, the open squelch was killing me.  Now I see my beacon
transmitted.  Next pass is 4:23PM EDT with a max elevation of 79.94
degrees.  If I can't get in, I am writing to NASA (just kidding).
