This is the hardware build of a new digipeater one of my friends asked me to put together for him. The transceiver is a GM300, with a KAM plus TNC modulating it. If we didn't happen to have a KAM+ on hand, I would have probably used an OT3m from Argent Data.
He'll provide the computer, but for testing I have it hooked up to a Qotom Q310G4 running Aprx.
As mentioned in the video, when I'm working with CAT5 cable, I love using the GreenLee 4908 toolkit.
