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
