Regarding the Ameritron RCS-4 choke burning up.
A responder mentioned a possible cure by shielding the relay box from
stray RF. I doubt that. BUT another wild guess would be high SWR
while transmitting high power. If someone was using a tuner before the MFJ
or an
amplifier in line I guess it could happen. BTW I used to use an RCS-4 and
probably
did just that but maybe I was lucky.
