Sorry, Brad...fingers hitting keys before cerubellum synapses kick in.
Reference your post...don't know if I can help. I've never seen a Ferret with Legacy series radios.
The only ones I've seen had C-42 sets installed.
However, should you have questions about Legacy series radios or C-42 radios...by all means shout me up.
This offer is also for all and any comms type guys and restorers who may have questions about the above radios, especially the installations thereof. Information shall be freely provided, as best as can be done.
After all, isn't this what the Forum is all about?
