Difference (from prior major revision) (author diff)

Changed: 5c5

RTTY was not fast by modern standards; a typical [baud rate]? for RTTY operation was 75 baud.

Changed: 7c7,9

RTTY is still in use today (2001): see the link to German weather broadcasts (RTTY at 50 baud using FSK) below.

The combination of low baud rate with robust FSK modulation made RTTY highly resistant to most forms of radio interference, second only to Morse code.

RTTY is still in practical use today (2001): see the link to German weather broadcasts (RTTY at 50 baud using FSK) below. RTTY systems are also fielded by [radio amateurs]?.
