Thanks to both Larry's. That answers my questions. I see where the current requirement of certain relays could be a problem, however a secondary relay system could be used to key the one requiring the higher current I suppose. Come to think of it, I am sure my old Dow key relay is a 110vac coil, so I will HAVE to use a second 12v relay to send 110 to the Dow key.
I've had problems with back EMF before, but there are ways to prevent that too, diodes, etc. Okay, Great! I was a bit worried for a moment that there was no keying voltage. Thanks Again, Brian / w5ami
