Some #hamradio updates:

1. Because US amateur radio licenses are public and include addresses, you can see a map of everyone with a license. It's way denser than I would have expected in Berkeley:
   

   

   And hey, there's @Daniel Filan with his fancy Extra-class license a bit further down on the map!

2. Today I managed to hear my first trans-pacific signal, from Nauru (a tiny island country 5,000 miles from here). Apparently it's what's called a "DXpedition", where a group of radio amateurs go on holiday in order to help other amateurs check "rare" countries off their lists. Unfortunately from their website, it looks like they're transmitting with more than ten times as much power as I have (or at least they brought equipment for broadcasting at that power level), so this isn't much evidence about whether I'll be able to have a full conversation with them or not.
