HANDY AND EASY SIGNAL GENERATOR UP TO 1.7GHZ
.This picture shows a modulator, from a video
recorder, it can be used as a simple signal generator.
A video modulator, "transmits" from the VCR, to the television set, normally between channels 32 and 38.
If you put an LF signal into the modulator, you get a nice FM modulated output
a very handy thing, when you have to tune a down converter to 1.7 Ghz.
So get a hold of the next old VCR you see.
