Nick Kennedy, Atari Morse Code Keyer I was adding a batch of ham radio newsletters to the Internet Archive's Digital Library of Amateur Radio And Communications, and I noticed the word "Atari" on one of the pages. In the September 2019 issue of Solid Copy, the newsletter of The CW Operators Club, Nick Kennedy had written: "Few hams who are both CW [morse code] enthusiasts and programmers of microcontrollers have been able to resist trying their hand at a keyer or two. I’ve done several in the past 30+ years, starting with one for the 6502 in an Atari 800 and on through PICs, AVRs and now...the Arduino." So I contacted Nick, amateur radio call sign WA5BDU, to find out what his Atari project was all about. First, a tiny bit of ham radio background: Morse code, that language of dots and dashes, can be sent over the radio waves using a Morse code key. Even if you know nothing about ham radio, I bet you picture a basic Morse code key: when tap the little lever, it makes an electrical connection that makes a sound. That's called a straight key. Avid Morse code enthusiasts may prefer a fancier "paddle" key: with two levers, one for short beeps and one for longer ones. A keyer is a device that is connected between the paddle key and the radio: it allows the sender to control timing of the transmitted signals, and other factors. Nick's software, WA5BDU Computer Keyer, turned his Atari computer into a keyer. He wired his Morse code paddle and his ham radio to joystick port 2. As he sent a message using his paddle, the Atari interpreted the signal, adjusted it as necessary, displayed the outgoing message on the screen, and sent the signal to the radio. Or, Nick could simply type on the Atari's keyboard to send Morse code messages, skipping the paddle key altogether. Nick sent me the keyer program and source code — as well as a packet radio terminal program that he wrote, and a tank game written by his brother. Check the show notes for links to all of those. Our interview took place on January 21, 2023.
