I recieved a MFJ-1278B TNC and have been working on getting it on the air. i have it working and I have been listening to the APRS packets and some nodes going back and forth 145.030. I'm wondering how is one to contact someone? I'm seeing linking stations but not just a call to connect to. I have been reading, and I'm seeing several diferent ways to contact someone, just wich one is right?
