(Warning: Ham radio jargon used in the following post. You've been warned.)
Over on the right sidebar of my blog (http://fueldepot.blogspot.com), I've added a map applet that displays my position via the ham radio APRS system. Interestingly, I found an iPhone app called iBCNU ("I be seein'you") that allows me to post my position on the APRS system using the GPS from my phone. Cool beans!
Now what I'm waiting for is an IRLP or Echolink app that will allow me to play ham radio (voice) via the phone. Come on coders, throw in another Hot Pocket and get cracking!
Peace, love and geekdom,
