How would one go about determining what's wrong in a Paccomm Tiny-2 TNC that's making it deaf? With the assistance of VE7GDH this morning, I was able to figure out what I'm supposed to be doing to do packet stuff. I have two TNCs, a Tiny-2 and an MFJ-1276, both second-hand. Prior to this help, I was able to pick up occasional ARPS packets from the MFJ, but not the Tiny-2 and I didn't know what the problem was. With VE7GDH's help, I could connect to the VE7SPR node on Salt Spring Island, just west of me, using the MFJ. When I tried with the Tiny-2, the node would note my attempt to connect, but the Tiny-2 didn't notice. So, I have a deaf Tiny-2. I figured that first a recapping would be in order, just because. What else should I look at?
