[GreenKeys] Aydin FSK/OOK model 380 demodulator

[Fred Weksberg]

I have an Aydin demodulator model 380.
Can't find anything on a google search.
I have a think manual, may as well be Greek, very complicated.
The previous owner said this was used to copy messages from North Korea.

It seems that the input is an IF signal (0.1 - 1 volt), rather than an audio signal.
Is that correct ?
Anybody used this demodulator ?

Thanks, Fred
