Thank you for your replies folks. Agreed there's no reason why it shouldn't work but I wanted some professional reassurance as well. I'm just waiting for an opportunity to plug it into an airliner's comms system and see what occurs. Nothing more dramatic than a CB popping I hope.
HD. I remember your liking for the Stratolite. I have yet to see one. I really like the Astrolites. It's fun buying them used and dirty, tinkering with them and cleaning them. And deciding what to do next ! Amazing how long they last.
