Must Be Software

Software programs released by Paul Williamson, KB5MU

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

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.
