Digital Sound - RTTY

 

 

The ‘original’ data mode. RTTY (pronounced ‘Ritty’) has been around for many, many years and is still just as popular. Years ago the only way to get on RTTY was to use a mechanical terminal unit such as the Creed 7 series, which were big, noisy and messy. These days, virtually all RTTY is done by the computer/soundcard combination. Amateurs (hams) use 45 baud (the speed) with 170Hz shift (between mark and space). Commercial stations use 50 or 100 baud with shifts of 425 or even 850Hz. Most software caters for differing speeds and shifts. Unlike most digital modes, RTTY is transmitted on LSB.
