[GreenKeys] Northern Radio Volume and Current Indicator...

[Roy Morgan]

Eugene,

That VU meter on your new gadget is a kind of a treasure - it appears to be
a high quality Simpson GEn You Wine VU meter.  Not easy to find and
especially precious in the world of audio.

The official organizaitons involved in audio work (RIAA and others)
published the official standard for such meters in the 30's or 40's.  That
is NOT a normal milliammeter with a rectifier on the back!

I can provide further details once I get to my archive of informtion.
Email me if you are interested.

The thing you have appears to accept audio signals and convert them to some
sort of signalling voltages - perhaps for transmission over FAX circuits or
radio broadcasts.

(I have not seen he manual yet.)
