Hi all, if anyone is into converting a Marine (500kHz) TX there was a
Marconi Salvor III ( quite clean) for sale at the Cambridge rally this
weekend. With 4 6146s ( I think) it is probably rated at 250 watts though
it
should be possible to push it to 400. It has a lovely 4in diameter
variometer. The slight problem is it is for 24volt supply.....portable
anyone??
It had not sold by lunchtime and I was told it will be at Luton. The
asking
price was 85(GBP), but if he humps it to Luton it may be haggleable.
I got a rush of meglomania (powermad?) on another stand where I managed
to
buy an RF Thermoammeter..........0-25 Amps !!! I could not resist as its
so
long since I last saw one at all at a rally. So anyone with 3kW and 10ohms
ground loss will have to come and haggle at Windsor!

Alan,
I saw the Salvor as well, I think that it covers down to about 410 kHz and
would be CW/MCW only, hefty beast for an emergency set! The variometer
looked as though it might be possible to squeeze more turns on the stator.
If you're in the market for a coil like that G4PFG (Harleston, Norfolk) has
another 100kHz Pulse/8 (Loran) TX for disposal, that has a large variometer
in it which appears to be made of Litz wire, I have a photo if anyone's
interested. I picked up a nice Racal 0-5 Amp thermocouple meter from Mike,
hope that's going to be enough when I get my 300 Watss going!
Roger, G3VKM
