Kenwood R-5000 Instruction Manual page 20

4-2-9. CW zero-beat operation
1. When an optional filter is not used, tune the TUNING
knob so that the receive beat frequency is approximate-
ly 800 Hz.
2. When an optional CW filter is installed the simplest
method to use is to adjust the TUNING knob for maxi-
mum S-meter deflection.
4-2-10. FSK operation (Radio teletype).
In the FSK mode, the R-5000 is automatically set for "High
Tone and Narrow Shift (170 Hz) operation.
The accompanying diagram illustrates the relationship
between the carrier and the passband width. The demo-
dulated AFSK (Audio Frequency Shift Keying) signal is
sent from the REC jack on the front panel.
Frequency relationship
Notes:
1. An RTTY terminal is required to decode and display/
print the RTTY signal.
2. Because the digital VFO resolution is 10 Hz, the dis-
played frequency may deviate 5 Hz from the space sig-
nal frequency, but this should present no problem in
acutual operation.
3. If you are using a low tone terminal unit, turn the tuning
knob to lower the beat frequency then turn the IF SHIFT
knob counterclockwise until the S-meter no longer fluc-
tuates.
4. To receive a wide shift signal, set the SELECTIVITY
switch or M1 or M2. To receive a wide shift, high tone
signal, turn the IF SHIFT knob clockwise until the S-
meter no longer fluctuates.
5. To receive AFSK (F2) signals, put the R-5000 in the FM
mode.
4-2-11. Receiving FAX (Facsimile) and SSTV (Slow
Scan Television)
Select the MODE key to match the receiving mode. Con-
nect the modulator, decoder, or other terminal unit to the
REC jack on the front panel. For more detailed informa-
tion, refer to the instruction manual supplied with the ter-
minal equipment.
