Classic Mac Packet Radio 

When I was a kid I did packet radio on a Mac LC, MFJ TNC (it could receive WEFAX as well), and a 2meter HT. Good times. I've used just a regular dumb terminal connected to the TNC as well.

Thanks for sharing, good to see vintage gear still works on air

144.39 is mainly APRS. There are other frequencies with different packet nodes and BBS functions.

Great video with very clear explanation of everything you did to operate this!

You Have a great collection!

Very neat! I’ve recently been playing with a vintage AEA PK88 and 386 PC. Still works!

I’m in the process of learning Ham radio and also into vintage macintosh setups. This is the exact video and setup I was wondering about. Did you end up being able to connect and do both Send and Receive traffic from your Macintosh SE/30?
