Building a cable to connect the Mobilinkd TNC to the TM-281A for APRS or other packet radio functions…
For my car APRS setup, I use a Mobilinkd TNC, an old Android phone, and a Kenwood TM-281A radio. If you want to do the same, here’s the pin out for the TRS, TRRS, and CAT 5 connectors that you need.
Questions? I can be reached at my call @arrl.org.
