[RTTY] Mono band amps

[John Barber]

Bill,

You can use ordinary 11 pin plug-in relays on HF with no problems. The
type I used for my 4CX1000 amp and auto antenna switcher are 12V coil,
double or triple contacts rated at 10 Amp. I bought a bag of these
relays at a junk sale for next to nothing and they have been working in
the amp for about 15 years!

Cheers,

John GW4SKA
