Class C Wavemeter

Ditto this side of the ditch Mike....many more BC221s than anything else.

The difficult part for 'us' is finding an unadulterated one.

This is my 3rd, the only one I have seen with the rear canvas still attached.

I have not seen any that haven't, as said in that great uTube clip you posted, been 'uprated' with a 240v PSU...this one has a Govt issue PSU, no idea what part of the Govt.

Maybe you or other forum members can help with this one Mike.
I'm not even sure if it had any military applications.

An AWA fanatic in Aus didn't recognise it but places its manufacture pre WW2.

I can't even rehome it.....too heavy to send across the ditch.
Although I did get the RNZAF to take a Rebecca Radar unit to England for the Imperial War Museums Duxford radio collection. What a mission!

I think I have too many test units

Where on earth are you finding this stuff Brent ?

I probably had a manual for that AWA device. I was given a big stack of AWA manuals , very old ones.

Have you run out of storage space yet ?

The BC221 was an amazing item, as that guy explained on u tube, it was a major leap forward . An error of less than a hundred Hertz .

we all fall across stuff that interests us over the years Mike, as you well know

I have accrued too much kit...and at nearly 60 I am making a real effort to part with it before I shuffle off this mortal coil.

My two daughters swear they will get a skip in ~grins~

I sold a WS38MkII last week...just taking some pics of a nice FS6 that's next on the block.

Beautifully made Signal generator by Ferris. high end WW2 kit.

I've photographed that beautiful valve allot..trying to capture those electrons as they leap around.
As I said, too much test kit'.

I'm not in the least concerned.....just being practical.
