CDMA Cellular Phones

If you had an early CDMA cellular phone, chances are good that some of its software was written by me and my (former) colleagues at Qualcomm. I retired in 2000, so I don't know if any of that code is still in modern phones.


InstantTrack is probably the best satellite tracking program (what's that?) ever written for the MS-DOS environment. Originally released in 1989 by Franklin Antonio, N6NKF, after over a year of vigorous development, the program stagnated at version 1.00 until Y2K bugs forced an update release. I created the first maintenance release, version 1.50, with the Y2K bugs fixed, some new features taken from Franklin's post-1.00 beta development, and some new features of my own. Few people were buying new DOS programs by 2000, but well over a thousand people purchased the upgrade, raising a tidy sum for AMSAT. Minor development continued sporadically, with post-1.50 upgrades released for open beta testing. Version 1.55 is the current (and possibly final) version.
