[Milsurplus] Unk receiver on Ebay

[elden meyer]

 Good Morning Hubert and group,
I have one of these in my stash. It was made for the FAAwho called it a modulation monitor. It consists, as I recall,of a single range oscillator, using either the fundamentalor harmonics, a diode mixer and an audio/video amplifier.
It was never intended as a receiver per se, just a deviceto demodulate an AM signal for analysis.
