A couple years ago I decided to get an amateur radio license. So, I bought a couple study guides, learned all about radios and their components, antennas, bands, and all that good stuff, and passed the test to get a Technician's license without a problem. Then I bought a radio, and it has patiently sat in my desk for two years waiting for me to program it.
To be honest, there are a lot of other things I'm much more passionate about, and I'm *very* rusty on everything I learned about radios. But...my name is in the FCC database with my call sign KE0BCA, so my interest in amateur radio is public record till at least 2024.
