Well I don't Know Mike. I think the box came from you as an empty unit and I acquired the internals a year or so ago off ebay. I seem to remember that you gave me the heads up about the auction. I have noted that the others shown here have a meter. Is mine wrong? Ron

The Pye connector is rather later than the WS11, and on your coupling unit appears to be fitted to a metal plate that blanks off the meter position.

Looking at the schematic in the WS11 handbook (Signal Training Vol.III Pam 19), the LP button operates a normally closed shunt to the 350 mA RF ammeter. Looking at it further, it appears to be Ammeter HF 350 mA No.1 which is a fairly common "plug-in" type, so there would have been a large bakelite socket behind where the Pye connector now sits. Also there appears to be a protective cover for the meter, secured by four screws (the socket has three), so if you have a look behind the Pye connector and that's the arrangement, I have a spare socket and can probably find you the correct meter. (The protective cover you'll have to make yourself, a block of wood and some perspex sheet ought to do it.)

Thanks for that Chris. In the morning I will take that plate off and see what is there and what you can help me with to get it correct.

Cheers Ron

Chris, this is what I have. Ron

Ah, right. A little light begins to dawn. There is no socket assembly as such for the meter, there are two receptacles fitted to the vulcanite panel that accept the meter pins. If you look at Plate X in the handbook, you can see how the meter fits at bottom left.

Unfortunately a previous owner has gutted your aerial coupling unit and turned it into "just a variometer", because the shunt and most of the other parts are missing from that area.

I can find you a 1941 Ferranti HF ammeter, but I think you're going to have to make the socket parts.

Chris.

[Ron Pier]

OK Chris. Can you PM me with details of how I can obtain the ammeter. I'll take advice about the installation at a later date. Cheers Ron

Here's a golf bag aerial kit on UK ebay if anybody is looking for one.
