The functions for RTTY operation (Continued)
D RTTY decoder
The transceiver has an RTTY decoder for Baudot (mark
frequency: 2125 Hz, shift frequency: 170 Hz, 45 bps).
An external terminal unit (TU) or terminal node con-
nector (TNC) is not necessary for receiving a Baudot
signal.
In the RTTY mode, push q
