Steve,

A great bit of history. Thanks for posting it and thanks for your 
involvement then, and now.

I can't believe this was going on 20 years ago now. The aprs sig messages for that period are available from TAPR's ftp server in monthly files. The QSY began in October 1997, just after the DCC. If you are curious who the doubters were, this and succeeding months are the place to look

It was a PowerMac 7300 on a T1 line at the Miami Museum of Science and had a half dozen IGates scattered around the country. All IGates were one way, I'd release two-way messaging at the 1998 DCC, though we were already messaging over the internet between MacAPRS and WinAPRS clients. MacAPRS was in it's third year, PC users had APRSdos and the two year old WinAPRS; APRS+SA was also on the horizon. APRS was just beginning to get some respect in the wider ham world, for example MFJ was making a data radio crystalled for 145.79. Things were different, to say the least!

It is pretty amazing to consider that in a year, by the 1998 DCC, the QSY was complete in most of the country. This really was a key moment in APRS history.
