This is a tiny thing I decided to build because I got tired of people waiting for other people to give them their APRS code. Some wait times reach weeks long.
This is a much faster solution which aims to remove emails and wait times. Less hassle for humans, less pissoff-ery for the person needing their code.
Give it a callsign, it checks for the validity of the callsign (so, US only at the moment) and bothers to generate the code if the call is valid.
xastir xastir (released under a compatible GPL license) is a cool peice of software. Thanks for the callpass hash method. I wouldn't have known where else to find it.
callook callook (callook.info) is a (very) fast, well behaved amateur license database. Uses data from the FCC, but has vastly greater performance!
