What's in QEX this month -- June, 1991
"A Microcomputer-Based Multimode Reader"
A small reader capable of deciphering Morse code,
Baudot RTTY, ASCII, and ARQ and FEC TOR modes.
Everything is printed out in plain English on an LCD,
or choose to save your copy via an EIA-232 serial port.
[Note: A great project for learning about
microcontroller chips. The author makes full source
code and development tools available, and the memory in
the Motorola chip he uses can be programmed by the user
without a special programming system.--KE3Z]
"EA-88 IBM PC Radio Interface"
A plug-in board that integrates the hardware needed to
permit easy interfacing of a standard IBM PC and modern
transceivers with computer-control facilities.
