The FCC maintains a database of licenses in the ULS, or Universal License System. Apparently they no longer mail out paper copies of amateur radio licenses, so the fastest way to check a license (including seeing if yours has posted yet!) is to simply check the ULS database. So, of course I’ve been checking the ULS daily (sometimes twice a day) to see if my license posted and what my first callsign will be.
Amateur radio callsigns are issued sequentially, according to license class. They do not go back and “fill in the gaps” by finding previously issued, but now available callsigns. In typical U.S. government fashion, they just charge on ahead. I saw a few days ago that new Technician and General class callsigns in California were in the “KN6XXX” range. As a 2×3 (two digit prefix, then the district number, followed by a three digit suffix), it’ll be a little “wordy”, but depending on the suffix, it might not be too bad.
Well, it posted yesterday!

The Federal Communications Commission decreed that henceforth on the airwaves, I shall be known as … KN6JDY. Kilo-November-Six-Juliet-Delta-Yankee.

It’s not the worst, but not the best, either. As a General-class licensee, I can apply for a “vanity callsign” of the 1×3 variety, which would be a little shorter. At least three syllables shorter phonetically. I’m in the process of finding one that resonates with me, but more on that later.
For now, I’m going to add some frequencies to a my Kenwood portable (more on that, too!) and at least get on some of the local repeater nets to exercise my newly-granted access to the RF (radio frequency) spectrum.
