[Heathkit] DX-60 Heathkit

[KH6ITY at aol.com]

I'm in the process of restoring a DX-60. I've ordered the manual for it but  
it hasn't arrived as of yet. The DX-60 has an octal socket on the rear. I  
remember as a teenager (when I had one) that the socket could be wired for a Dow  
coax relay for switching from receive to transmit. However, I can't quite  
remember the voltage for the relay. I think it was 115 volts, but I can't  
remember for sure. Can someone help me out?  Regards, 73's   Larry  kh6ity
