Why amateur radio?
I get this a lot. "Why are you interested in ham radio?" My answers never seems satisfying--probably because most personal interests do not fair well in the harsh light of inquiry. Why are people interested in golf? Spend upwards of $100 or more for a few hour’s frustrating attempts to hit a very small ball with a very large stick a very long way, followed by tapping that very same ball a very short way, often with abject failure on all counts, hardly seems like a reasonable pursuit, either. (I should know... I used to play golf.)

How about bowling? Throw a ball at wood. Repeat. Again, these terse descriptions fall short of the actual experience of golf or bowling.

I enjoy amateur radio because I enjoy learning new things about the physical world and geography, and I enjoy building things and then using those things I've built. There is also a competitive aspect of amateur radio that anyone who enjoys golf, bowling, or any sport would enjoy. Contesting allows radio operators to compete for points and match their skills at building a station, and subsequently operating that station, competing against others in broad categories. If poker can be a sport, ham radio can be a sport, too.

I have, through amateur radio, been able to build things that can communicate with people tens of thousands of miles away. I have been able to compete in contests and do reasonably well. I've had reasons to learn geography and world events beyond any prompting that school teacher could ever provide. It has renewed my interest in travel. It has been fun.

Amateur radio isn't for everybody anymore than golf, bowling, NASCAR, classical music, or Oprah's book club is for everybody. But, if you have an interest in technology, like to build things, like to travel, or just enjoy meeting new people then this hobby may be of interest to you.
