UHF 225-380 MHz Milcom Spectrum Holes

I have written a lot over the years on this blog and other media about what I call spectrum holes in the 225-400 MHz range. In brief a spectrum hole is a legit frequency for assignment based on current channel spacing and the DoD bandplan, but no activity/current assignment has ever been heard/found for a frequency. That is a spectrum hole. If you are interested in exploring the world of 225-400 MHz spectrum holes, I have now created this page for those who want to monitor a challenge. And if you hear something or know something about one of these freqs, I would appreciate an email at the address in the masthead.
