Sooner or later it happens to everyone, it depends on how you use the radio to know if "BEFORE" OR "AFTER"...
?
The first time I shorted the contacts with the other position, then that one also blew and I replaced the switch completely with a new one which I found identical.
?
It has held since then, but it will happen again...maybe...
I always use the radio, now these days I notice another problem that gives me little VHF power... maybe the power amps or something else...
I've been using it for years and years now... something had to happen... unfortunately.
