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. Gateway (column) DSP dreamland at Dayton; TAPR METCON-1 beta-test kits available; TAPR DSP hardware update; FCC and "the PBBS eleven"; GB1MIR/U to operate from MIR; NTS embraces digital systems; and the YU3 23-cm 38,400 bit/s packet- radio network. ----- Jon Bloom, KE3Z | jbloom%arrlhq.UUCP@uhasun.hartford.edu American Radio Relay League | uhasun!arrlhq!jbloom 225 Main St. | Newington, CT 06111 | "This mind intentionally left blank."

What's in QEX this month -- July, 1991 "PSK Anyone?" A 1200-baud PSK demodulator designed specifically for narrow-band applications. A practical HF packet alternative. Components (column) The microprocessor--a programmable logic component. Also, MEC surface mount switch, 2-gigabyte disk drive, tiny RF mixer, and RF connectors. VHF+ Technology (column) Mid-year notes...VHF+ radiation and microwave devices. Gateway (column) U2MIR bids farewell and U5MIR wants to know "what's up?"; AMSAT-NA annual meeting and symposium; thoughts on BBS authentication; and new packet software releases. ----- Jon Bloom, KE3Z | jbloom%arrlhq.UUCP@uhasun.hartford.edu American Radio Relay League | uhasun!arrlhq!jbloom 225 Main St. | Newington, CT 06111 | "This mind intentionally left blank."
