I have just sent myself a test message and the linkseems to be OK. Mike

 Sorry, I didn't receive your request. It iscertainly still open maybe the link is broken. I will check with Murray. In themeantime send me your request direct to me. Sorry for the

Hi Conrad Apologies. I did know this of course. Typo! Paul G4DCV

In the past I've used a fairly simple solution of just fitting a series resistor that will allow enough current to hold the relay on with a 1000uF capacitor across it. Works for me. Roger GW4NOS

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. Regards Conrad PA5Y

I put a request in a few days ago but nothing heard ...is the bank still open?

Ok Peter, thanks a lot for the effort, also on behalf of DC6IB, who has no access to the internet himself. Great to have a probable similar circuit-diagram. It will probably help to clarify a lot, I

Rein, My message was rejected again so I have uploaded the schematic to the files section. 73 Peter G3SMT

Hello, This email message is a notification to let you know that a file has been uploaded to the Files area of the ukmicrowaves group. File : /Marconi6910.pdf Uploaded by : peter_g3smt

Rein, It is only 275kb but your mailbox also rejected my earlier message. I will send again. 73 Peter G3SMT

Peter, how large is the file, you can send up to 5MB directly to my email otherwise we can refrain to wetransfer. Did you use that before? Best regards Rien

I was thinking along those lines too, Andy...but without the device knowledge! Mike 'LYP had some good ideas on here last year about devices with which to control heated masthead enclosures (to

It maybe worth considering a customised bit of drive circuitry; one that pulls in at a high voltage than drops to a lower holding value - or a constant current supply. Both manageable with

There could be a case for evaluating that in advance (and maybe with any model?), i.e. powering it up on the bench and checking the temp. rise. It's possible that's how mine failed in it's previous

That's where I read it, Paul - well found! I have a similar (as in y-shaped) relay (with a duff solenoid as it happens) and was looking for an internal picture of the Transco to see if it's

Rein, Tried to send the information to you but it was blocked by :- hostkarma.junkemailfilter.comHow should we proceed?73PeterG3SMT

Hello Peter, Thanks that might be of great help 73es Rien

Hi Al Follow up to the message I sent a few minutes ago. I also found this in the instructions for the JWM sequencer, "A word of caution related to RF relays that are always in a

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

Rien, The usual cable has 12 connections. I have the manual for the 69-- series which is a later version of yours but I am unsure if its the same. However, the circuit may give you
