Rtty (Fsk) OperatOn - Icom IC-7600 Instruction Manual

■ RTTY (FSK) operation
A DSP-based hgh-qualty Baudot RTTY encoder/
decoder s bult-n to the IC-7600. When connectng
a PC keyboard (pgs. 18, 19), RTTY operaton can be
performed wthout an external RTTY termnal, TNC or
PC.
If you would rather use your RTTY termnal or TNC,
consult the manual that comes wth the RTTY term-
nal or TNC.
q Push a band key to select the desred band.
w Push [RTTY/PSK] to select RTTY.
• After RTTY mode s selected, push and hold
[RTTY/PSK] for 1 sec. to toggle between RTTY and
RTTY-R modes.
• "RTTY" or "RTTY-R" appears.
• RTTY tunng ndcator appears.
e Push [DECODE] (F-3) to dsplay the decode
screen.
• The IC-7600 has a bult-n Baudot decoder.
r To tune the desred sgnal, am for a symmetrcal
waveform and ensure the peak ponts algn wth
the mark (2125 Hz) and shft (170 Hz) frequency
lnes n the FFT scope.
• The S-meter ndcates receved sgnal strength when
sgnal s receved.
