Picked up a pair of Macom Gunnplexer transceivers the other day.
Today was the first power on to verify they are working.
Next is to FM modulate the supply to transmit tones/audio.
After that is is receiver time.
Eventually the plan is to have a pair of limited range, very directional 24 GHz walkie talkies - just cause I can!
I will update this thread with progress as I go.
