Operation With A Linear Amplifier; Fixed Frequency Operation - Kenwood TS-820S Instruction Manual

The crystal frequency is determined by the following formu
las.
opposite station becomes a zero beat signal (zero beat signal
can be easily noted by turning IF SHIFT knob).
This completes the zeroing of the transmit frequency. Turn
the RIT knob for your desired pitch of sound.
Crystal Frequency (MHz) = 55 MHz

x = 1.8 for the 160 meter band
X = 3.5 for the 80 meter band
X = 7.0 for the 40 meter band
X = 140 for the 20 meter band
X = 21 0 for the 15 meter band
X = 280 for the 10 meter band or
X = 28.5 for the 10 meter band or
X = 29.0 for the 10 meter band or
X = 29.5 for the 10 meter band

circuit.
Example: Desired Operating Frequency = 7.255 MHz
Crystal Frequency = 55 MHz + 7.0 MHz -
7.255 MHz = 5245 MHz
This same crystal will operate on each band
Operating Frequency = 5.5 MHz + X (in MHz) -

Recommended monitoring position during operation,
Example: Crystal Frequency = 5.245 MHz
On the 14 MHz band the crystal will oscillate at
Operating Frequency = 55 MHz + 14.0 -
5.245 MHz
= 14255 MHz
4.14 OPERATION WITH A LINEAR
AMPLIFIER (See Fig. 30)
Tune and load the TS-820S as described in Sections 4.1
through 4.11 and adjust it for the selected mode.
The REMOTE connector on the back panel is provided for in-
terconnections with an amplifier. See the instruction ma-
nual of the amplifier to determine whether the linear requires
a normally open Iduring receive) or a normally closed (during
receive) relay contact. Connect either pin 3 (normally closed
to ground during receive) or pin 5 (normally open to ground
during receive) of the REMOTE connector to the control jack
on the amplifier.
Connect the ALC feedback from the amplifier to pin 6 of the
REMOTE connector. The output of the TS-820S is quite
adequate to drive most amplifiers to full rated output.
4.15 FIXED FREQUENCY OPERATION
The TS-820S has a built-in crystal controlled oscillator for
fixed frequency operation. This feature is most useful for
commonly used frequencies. nets. or any situation where
crystal controlled operation is required. To use the fixed fre-
quency oscillator. turn the FUNCTION switch to the FIX po-
sition. Select one of the four available channels with the fi-
xed channel selector switch and tune and load the TS-820S
as described in Sections 4.1 through 4.11. Simply operate
the transceiver as described in Sections 4.12 and 413.
