I wrote an email system that will email you a APRS station’s info (last heard time, position, and APRS status).
To use the system, just send an email or SMS (text message) to aprs@tomh.us with the station’s callsign at the start of the message. Emails must be in plain text format, not multipart/HTML.
You should receive a response in about a minute. It will look something like this:
