Good description,
Beware of shock (when opened) sticker should be heeded.
The one I have I modified to have a bright LED light up the display instead
of a hot wire lamp-

We have used one for off-air FM. The fidelity sounds like the demod is
missing de-emphasis--really tinny. I tried opening the unit to look for
firmware jumpers but couldn't find much of anything. It reminded me of
a Lloyds radio in a different package.

We bought about 6 of them when were doing a set of build outs last year.
So far all but 1 have
died in service. Three of them had a manufacturing defect (wrong size
Zener diode) that caused the
unit to scramble the display frequently and when it did the thing died
and had to be turned off for
a while. I fixed one of them per an instruction sheet sent to me by the
factory, but in
frustration (every time I would get one fixed another would die!) I
finally trashed them all. Even
when they worked, the audio quality was not that great. Definitely not
what I would want for an
off-air receiver in a control room. Really a shame because as Jim T.
already mentioned, they look
really good. I think we are still using a couple of them for music on
hold receivers for the house
phone systems.
