Keep the soldering iron hot.

-------------------

I saw another spy type Tx/Rx when I was in college (Colchester) about 1967. This was in the form of a small hip flask. It was on display in one of the labs until it was stolen. I don't know if it was ever found or returned.
Cheers,
Boiss

I didn't nick it honest.

Sounds like a Type 31/1 Receiver and/or a Type 51/1 Transmitter to me.

I'll try to post some pictures later.

Here are some drawings of the Type 51/1 "Hip Flask" transmitter. The associated receiver type 31/1 was similarly shaped.

I've just about given up collecting spysets now, as current prices are more than I'm prepared to pay. Apart from that I have several awaiting repair/restoration. I'd better get them finished before morse reaches the end of the road.

The following books have useful information on spysets including circuits etc:-

Wireless For The Warrior Volume 4 Clandestine Radio is available from this website:-

http://home.wxs.nl/~meuls003/progress4.html

Secret Warfare by Pierre Lorain. ISBN 0-85613-586-0. I think this is out of print, but may be available from your local library or secondhand

You've probably come across these pictures before but here they are for those that haven't. I've had them quite a while but unfortunately can't recall where they came from.

Great bits of kit though.

Do you have a spy set like this Graham?

The water bottle radio design comes from this site:-

http://www.webex.net/~skywaves/home.htm

I don't have one in my collection, as I doubt if any originals survived. They would have been constructed in P.O.W camps rather than in a factory.

I do have a leaking water bottle which is ripe for conversion though. I would have expected a water bottle radio to have a divider across it so that it could actually contain some water. A heavy water bottle which contained no water would have been very suspicious.

To my mind a "spy" radio should both transmit and receive, so I would classify the water bottle radio as a covert receiver. Interesting that it apparently worked with 12 volts of HT.

Graham,
If I remember correctly the spy radio really had the shape of a hipflask ie it was curved, I've no idea if it was a Tx,Rx or both. The Lecturer who was in charge of it was a Mr Howe.aka. "Dipole". At the time I made a 1" green (CV320?) TV in a 38 Set case using all EF91s apart from the tuner. Happy times!
Mike.
