Teletype Corporation Model 19ASR
This weekend is the CQ World Wide RTTY DX Contest, another one of my favourite contests of the year. And it is also my favourite mode of RTTY, a digital mode that is now transmitted and decoded by computer, but used to be transmitted/decoded by a machine before we all had PC’s. These machines used to sit in a corner of the shack “chattering” away to themselves where the sent message was on a tape typed by the typewriter kind of letters. All good fun but noisy, now the computer sends the tones and is a lot quieter as the received message is on screen.
If you have never had a go and have your kit set up for FT8 or other digi modes then this is easy to have a go. The software used here is N1MM which will log the QSO and create a contest entry for you too.
