It’s amazing how inexpensive technology can be. The new “toy” Mattel Hot Wheels radar guns have, well, a real radar gun inside. As in a 10ghz microwave emitter. Here’s some details (I might add a few more links later, but this should get you started):

got one and opened it up, I am looking to retune and use for an amature radio tranciever.
I soon found it tuned down to the ham band easly,setscrew out 1/3 apx. it is an oscilator and mixer. the output has a chip cap to ground so that would be removed to get a 50 or 100mhz if freq out.
basicly here is a recieve converter for x-band for 17$ on clearance at walmart.
almost a gunplexer, I will further get this coupled to a wave guide and also find out about modulation methods.
I have one of these and accidentally knocked the phase relays out of sync with the wavetable, superplexing the sin wave frequency modulator. Needless to say I’m now receiving messages from outer space!
