Antenna switch for 2 radios - dvttenhaus-sasbachwalden
So I’ve repurposed an MFJ-1702C antenna switch to be a radio switch instead. The two HF radios connect to the A and B “antenna” ports antenna connects to what would normally be the single radio port. MFJ Antenna Radio Switch is not a duplexer. I will never attempt to use both radios at the same time. That wouldn’t even work with how the switch.
