    This program for the Timex-Sinclair 1000 computer was written for completely automated design of Butterworth low-pass, high-pass, band-pass or band-stop filters. Modern solid-state transmitters are more prone to harmonic and parasitic frequency radiation, and therefore it is desirable for the radio amateur to have access to modern filter design in order to comply with present…

QZX was a newsletter for people with a combined interest in amateur radio and the Sinclair—Timex computers. Hams would have regular “meetings” on-air. For example, one group met Wednesday nights at 10 p.m. EST on the 20 meter band, at about 14.345 MHz.

Peak publication of QZX was 300 copies per issue in the early 1980s. By 1987, circulation was at 100 copies per issue.

QZX was published by Alex Burr.
