Re: FS: Transco Y Relay

Conrad, PA5Y

It's G0RUZ - G0CUZ is called Colin and is well known to all. It was a pain when we were both on CW eme in the mid 90s. What a very interesting thread.

Hi Al

This sent me leafing through my well-thumbed copy of the VHF/UHF DX Book. BTW I wish we had a modern version of this book. No mention of the Transco in the section about coax relays but there is a thread (started by Conrad G0CUZ/PA5Y) on Moon-Net that does indeed suggest heat sinking the Transco is desireable:

Useful info for anyone who needs to service or repair a Transco here:

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.
