Hello all, I'm currently trying to build an amateur tv transmitter using a 10ghz microwave doppler module such as this one
http://www.amazon.com/SMAKN-Microwave-10-525GHz-Doppler-Detector/dp/B00FFW4AZ4I have managed to modulate audio over this module without any issue however I've never worked with analog video before. I'm looking to hopefully take a composite video source, amplify it with a transistor and then use that to drive the module modulating it on the 5v input pin.
Thus far I haven't had much luck, I have managed to get it to transmit on the 10ghz ham band and down convert it with an lnb, sure enough I can pick it up on channel 60, 40, etc. What I see is a black screen while transmitting telling me I have a working carrier frequency.
If anyone is interested here is my attempt:
Is it possible to modulate video with one of these?
EDIT
I found this in an old magazine
Not sure if this will work on this module or not as it's not a gunn diode, but I'll give it a chance if I can salvage the needed components and post back here if it works.
