Re: OT2 and Alinco DR135 as an IGate
- Not to berate the obvious, but take a small speaker or headphone
with pigtail wires, and probe for audio all the way from the
radio to the actual circuit board in the TNC. Make sure you
also hear the packet racket there, just in case you have a PL tone
or something inadvertently turned on.
Had a friend with an unresponsive KPC3, and I did that, and no
audio. He says "But I wired it right!" Well, obviously, something
is wrong and its not getting to the TNC, so go to work, I said.
A couple hours later, he has it up and running. I think he counted
the db9 pins backwards or something like that.
