More on HB100 10 GHz frequency agility

In the previous post I wrote about measuring how much a stock HB100 radar module can be moved in frequency. I did another test to answer "where does the frequency go if the metallic shield is removed?"

This test is purely academic since the exposed DRO is much more sensitive to hand/object proximity and temperature changes, therefore unsuitable for most - if any - HAM radio applications. I got a delta of about 360 MHz, so the naked circuit was transmitting somewhere around 10'165 MHz.
