Any hams around?

So, I am far from the most experienced, or the most knowledgeable, or the most active amateur radio operator out there, but it is something that has piqued my interest none the less. Before I got into the hobby, I always assumed that the FCC just game amateurs a small bucket of useless spectrum and that was it. Maybe you could fly an RC plane, but surely that is about as cool as it gets.

It turns out I was dead wrong. Amateurs are allocated bands all across the RF spectrum - more or less. Bands from way below the AM broadcast frequency to way above the microwave frequencies used by our cell phones and wireless routers. Also, you are allowed to legally transmit at up to 1.5 kilowatts of power! That's 3,000 times as much power as your average walkie talkie! :) Also, importantly, the license exam only costs $15.

At many of the lower frequencies, the signals bounce off the ionosphere and you can make contact with people all over the world (propagation gods permitting). At the higher frequencies, you lose that "skip propagation," but more bandwidth is available. There are analog voice repeater networks, digital packet networks, mesh networks running on modified commercial WiFi gear, and even a handful of old school packet BBSes. There are some LEO satellites which run voice repeaters which allow you make international contacts, and sometimes even the International Space Station will participate in events. Lots of cool stuff going on. This hobby is kind of a bottomless rabbit hole of possibilities.

I got my technician license about a year ago, and I have been most interested in the data networking end of the hobby. Despite being a pile of hacks, APRS is still very cool, and sometime soon I hope to set up an AREDN node of my own. Every once in a while I'll call into the local repeaters and shoot the breeze.

So there's my story. Are there any other hams out there?
