Baofeng UV-5R as a 10GHz beacon and test source
Channel: oh2ftg
Date: 2021-01-16

The 24th harmonic from the Baofeng UV-5R's receiver leaks audibly and the "dual watch" function modulates it. 
So put the radio on 432.0125MHz and enjoy a beeping test signal on 10368.183MHz!
Got the idea for the test from a video by YO8RHI:
