[Boatanchors] Solid State Relay Question

[Rodger]

Hi Greg,

I replaced the plate relay in my Johnson Desk KW with a pair of solid 
state relays and I also use solid state relays to control the primary 
power in my homebrew triple 4CX800 amplifier.  They work well in both 
applications but you should put RF chokes and bypass caps on the control 
line near the relay to keep RF off of that line.  RF on the control line 
causes some very strange effects!  Most of the solid state relays have 
built in MOV protection also.
