Rtty sub bands
WebAn RTTY signal is a single carrier (like CW), but instead of being modulated on and off like CW, the transmitted power is kept constant, and modulation is imposed by changing the frequency by a preset amount; in amateur usage, the historical practice is to use a “shift” of 170 Hz. That is, RTTY is modulated using frequency-shift keying (FSK). WebSet the radio dial at the bottom of the sub-band and work stations on audio frequencies within the radio passband typically 2.5-4 kHz wide. If a sub-band becomes crowded, move …

Typically, the 100 watts is averaged so that the peak signal is about 200 watts - called peak-envelope-power. The bandwidth of an SSB signal is approximately the same as the maximum modulation frequency.
WebA RTTY signal involves two frequencies, referred to as markand space; the sequence of 1s and 0s representing a character are conveyed by appropriately switching an RF carrier between these two frequencies. The switching occurs rapidly enough that, when seen on a PC-generated audio spectrum display, a RTTY signal
