Can anyone tell me about this please?
I picked this up some time ago, I don't really know enough about it!
Any thoughts? Thanks.

Re: Can anyone tell me about this please?
It was obviously an aerial tuning unit but looks like it has been very much got at and is now a power supply.

Looks like originally it was a plug in Range B (CAY 47151A):

Re: Can anyone tell me about this please?
Yes it looks like it's been 're-purposed' and what it says on the back bears no resemblance to what it is now!

Re: Can anyone tell me about this please?
Putting GP-7 wireless into Google came up with the following:

I'm sure I saw that 'thing' being hawked round a few rallies (Frome, Harwell) in the last year....

Re: Can anyone tell me about this please?
It certainly looked great before it was got at.
Have you opened it up to see if it is a power supply?

Re: Can anyone tell me about this please?
Looks like it may have a speaker under the hole top left so I'd guess an amp as well maybe?

Re: Can anyone tell me about this please?
Do the bottom right sockets say Tx Rx though?

Re: Can anyone tell me about this please?
The 2 jack-sockets next to the 'speaker' do suggest perhaps they're for audio input/output.
I'm really intrigued to see what's inside the box. My thought is that it will contain a PSU built to power some item of WWII-vintage stuff (R1155?). |

Re: Can anyone tell me about this please?
Looks like an earphone has been fitted underneath, - top left?
Intriguing! David. |

I'll open it up later if I get a chance and take some photos and post them here.

Re: Can anyone tell me about this please?
Well, it once was a tuning unit but now it's got a cobbled-together power supply in it, complete with a dynamotor.
There should be voltage ratings on the dynamotor. The iron magnetics may just be filter chokes and not transformers. David

Last photo shows a small motor inside the unit.
