Showing my first methods used for Pan Adapter on my HF radio. Works well enough especially as a test bed, but better methods are available. Important because of the links so you can do the better methods yourself.
Radio without a Pan adapter system is a far cry from optimum, it seems to me to be required equipment anymore. Thanks to Don WS4E and Dave G4HUP for their kind assistance and guidance.
