Thank you for the information, but another person had suggested the
Ameritron ARB-704 Interface Buffer, for $50. I have installed this device
and it seems to work fine.

I am also glad to know about Harbach Electronics.

Harbach Electronics makes an interface module that might work with
your setup. Drop them a line and check. I think it sells for around 23
dollars. You could homebrew one, but you'd have to know the keying
voltage and current drawn by the relay in the amplifier.
