Re: FS: Transco Y Relay
Chris made reference to the coil resistance of the relay. I have an Amphenol relay with a 110VAC coil. I believe it's R is ~550 ohms. It's not to hand just now, but I will check it later. Thanks to Peter for that rule of thumb - I will need to know that too at some stage!
I don't recall which book/mag/internet article I was reading recently, Paul (it could have been the VHF DX manual), but there was a reference to relay heat sinking. The general thread was that if the relay was energised for RX, it would be a good idea to do so.

Subject: Re: [ukmicrowaves] FS: Transco Y Relay
As the one that bought the Transco from Chris can I say many thanks to eyeryone for all the advice about operating it on DC. It is very much appreciated. With 110V AC coils I had expected to have to put it in the amplifier and move the amplifier relay to a new masthead amp. But if it will work on 50V DC then I'm happy to put the Transco at the masthead.
I gather it's a good idea to heatsink them by bolting the relay to a lump of aluminium?
I have been after a Transco Y relay for some time but used ones (who can afford a new one!) only seem to come up for sale on ebay in the USA with eye watering postage costs.
