Drat. I forgot about APRS. APRS has become fairly popular among hams, so much so that it now comes built-in to several radios, and even HTs (Handy-Talkies). APRS is a system for location reporting. It's also very commonly used to track experimental weather balloons at high altitudes, because apparently GPS stops working at around 30,000 feet. [The original high-altitude MIT balloon launch that many others have duplicated uses APRS, and I know of other groups using it for this purpose also.] APRS is also commonly used by hams to track themselves and/or their cars and loved ones as they drive around. The rigs used in cars likely aren't running a Linux OS, but the base station nodes that receive and report the APRS traffic probably are, and as Debian has been friendly to hams it's one of the more likely to be used there. -- Chris, KB2IQN -- Chris Knadle chris.kna...@coredump.us GPG Key: 4096R/0x1E759A726A9FDD74
