HF all-band SSB/CW/RTTY
Transceiver employing PLL system
This equipment is a SSB/CW/RTTY
Transceiver covering 1.8 to
29.7 MHz frequency bands (WWV; 15 MHz) in which an ideal
circuit configuration has been achieved by employing a newly
developed PLL technique.
Thanks to employment of a FET balanced type mixer in
bination of MOS FET and a single conversion system,
excellent performance is obtained in both the spurious
radiation characteristic and receiving two-signal
characteristic.
Built-in IF shift circuit
The IF shift circuit used, also called a pass-band tuning
circuit, shifts the pass-band of intermediate frequency
is radio interference, the pass-band can be shifted or the
receiving frequency response can be set to a desired band
only by manipulating one control knob.
Built-in RF processor
This
Transceiver is provided with a unique speech processor
developed by
Kenwood. This circuit serves
Due to processing at high frequency, the resulting
distortion is minimized and deterioration of the tone
quality is prevented unlike clippers.
RF negative feedback is applied between the final
transmitting stage and the driver stage to suppress cross
modulation distortion. The good-reputation high-quality,
transmission radio waves are improved further by com-
Newly developed analogue dial
monoscale dial and subdial it is very easy to read
frequencies. Since such a circuit that a carrier frequency
is kept unchanged regardless of change-over of operation
mode is employed, each frequency is accurately indicated
only by one dial index.
Since die cast is employed for the front panel and the
chassis is constructed in the sufficient consideration of
strength, the
Transceiver maintains high mechanical
stability even when installed on a vehicle. The reduction

of knobs designed on the base of human

Unlike conventional transceivers.
TS-820 incorporates a
monitoring circuit that permits the operator’s speech to be
monitored by himself during transmission.
Audio frequency response change-over circuit to be used
during SSB or CW receiving.
During CW receiving, audio frequency band is automatically
narrowed to obtain tone quality easy to
Built-in fixed channel circuit with RIT (crystal; op-
This
Transceiver is provided with a fixed channel circuit
having RIT. Since cross operation is possible between this
circuit and built-in VFO, high technical Operation is
This
Transceiver permits combination use with transverter
TV-502 (for 2m) only by connector connection. Automatic
change-over can also be effected between HF and VHF by using
the power switch provided on the
Transverter.
Built-in AC

Mobile operation of the
Transceiver can be performed by
equipping a DC-DC
Converter unit (DS-1) available at option.
This
Transceiver is provided with wide variety built-in
accessory circuits such as a noise blanker, VOX circuit,
side tone circuit, maker circuit, built-in speaker, AGC
3-position change-over switch, heater switch, IF OUT
terminal and connection terminals for a linear
Amplifier.
