Wondering why this website is named KD9CPB instead of something more sensible? Well the answer isn’t as exciting as you may have expected; KD9CPB is my ham radio callsign issued to me by the FCC! One of my technologist friends talked me into studying for the amateur (aka ham) radio technician test in the mid-2010’s, and I’ve been fascinated by the entire radio spectrum ever since. Hamvillage.org really says it best: “Ham Radio is in may ways the original ‘hacker’ culture and ‘maker’ community”.

One of my favorite things about ham radio is you only need about a day’s worth of studying, less than $20 for the license test, and a <$50 walkie talkie to start having lots of fun on the airwaves. Many of the posts here will dive into topics that would be more interesting after obtaining a ham radio license, but I’m hoping some of this content motivates more computer nerds to become radio nerds.

Back when wifi was first starting to become popular in the mid-2000’s, I discovered BackTrack 2 and quickly became addicted to learning more about wifi radios with Kismet. Those “Linksys WRT54G golden era of wifi” days are long gone, and my level of interest about wifi has since declined, especially now that everyone’s smart about not having open or WEP secured access points. That being said, recently I’ve been having almost as much fun with SDRPlay’s SDRUno product as I did back in those WEP-era days of Kismet, and maybe you will too after reading some of these posts!
