Please be careful using this, any form of radiating RF equipment is regulated by the FCC and RADAR is one thing which is highly regulated. Otherwise, this is cool as hell.

Awesome project! Very cool.

I’m also amazed you’re able to get a 11GHz signal through a through-hole cap!

once you have it more refined a bit, if you want to make it more accurate do what police do. use 2 tuning forks for different freqs, that way you have 2 shift references and know its accurate.
