                                     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.

3.	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.

4.	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-
6. 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
gears of the PLATE and LOAD knobs, the shape and arrangement
of knobs designed on the base of human
dial construction easy to read.
Unlike conventional transceivers. TS-820 incorporates a
monitoring circuit that permits the operator’s speech to be
monitored by himself during transmission. 
9. 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

10. 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.

12. Built-in AC power supply and attachable OC-OC convertar

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.

14.	Systematized optional equipment

Optional equipments are fully provided such as remote VFO
VFO-820, external speaker SP-520, CW filter YG-88C, digital
display DG-1, transverter TV-502 microphone MC-50 and
low-pass filter LF-30A

15.	Use of digital display dial DG-1 (option)

1)	Digital display dial

The digital dial of TS-820 indicates transmit and receive
frequencies using carrier. VFO and local oscillator signals
instead of converting VFO

Since the accuracy of frequencies is set up only by
read accurately up to 100 Hz order by calibrating the
oscillator with WWV.
The green indication on the dial assures many hours
