I've had my ham radio license for almost 30 years, but I haven't done much since I moved to Colorado. 2 years ago, coworkers told me about DMR, which I didn't do much until recently, and I just found out about CARBBN and AREDN. Broadband data transfer is very interesting to me. Compared to 1200 or 9600 bps packet radio, this is leaps and bounds beyond.
