Information

1. PLL System, HF Band SSB/CW/RTTY Transceiver This Transceiver employs newly developed PLL (Phase Locked Loop) circuit, covering 1.8 to 29.7 MHz (WWV 15 MHz) for SSB, CW and RTTY operations. 2. Minimum Spurious and Excellent Overload and Crossmod. Characteristic The adoption of FET balanced type mixer, MOS FET and single conversion system minimizes spurious during transmission and assures excellent overload and cross- mod. characteristic during reception. 3. Built-in IF SHIFT Circuit IF SHIFT circuit is built in the Transceiver to shift IF pass band without changing receive frequency. The circuit is also called the "pass band tuning circuit". It allows you to eliminate radio interference or set the receive frequency characteristic to the desired bandwidth simply by manipulating one control knob. 4. Built-in RF Processor The unique speech processor uses a quick time constant at 455 kHz. Since this circuit is of RF type, it produces little distortion and, unlike the clipper system, does not deteriorate the tonal quality. 5. RF NFB RF NFB from the transmit final stage to thp driver stage improves the cross modulation distortion. The use of the amplification type ALC further improves the quality of transmit signals. 6. Newly Designed Analog Dial The combination of newly designed mono-scale and sub-dial provides easy reading of frequencies. The adoption of a circuit that is completely free from changes in carrier frequencies permits accurate indication of frequencies on one dial pointer. 7. Digital Display Dial The digital dial of TS-820S indicates transmit and receive frequencies using carrier, VFO and local Oscillator signals instead of converting VFO frequencies. Thus, accurate frequencies can be read at all times at any band and any operating mode. Since the accuracy of frequencies is set up only by the 10 MHz standard Oscillator, frequencies can be read accurately up to 100 Hz order by calibrating the Oscillator with WWV. The green indication on the dial assures many hours of fatigueless operation. 8. D.H. (Display Hold) SWITCH By pressing the D.H switch, the frequency read on the digital remains on, thus serving as a memory system. 9. Rigid Structure and Easy Operation The Transceiver is built with a die casting front panel and a rigid chassis, providing outstanding mechanical stability for mobile operation. All the operating parts such as control knobs and dials are designed and arranged according to human engineering technology to ensure maximum case of operation. 10. Monitor Circuit The monitor circuit allows you to hear your own voice during transmission, which is normally impossible with conventional transceivers. This is very useful when checking the modulation condition or adjusting the RF processor. 11. Selector Switch for SSB/CW Receive Frequency Response During CW reception the audio frequency response is automatically narrowed to improve the clarity of sound. 12. Build-in Fixed Channel Circuits with RIT (crystals are optional) The fixed channel circuits with RIT permit the use with the built-in VFO for more enjoyable operation. 13. Transverter Connector Transverter TV 502 (2m) can be connected for ready operation Changeover to HF or VHF is accomplished automatically with the power switch of the Transverter. 14. .Built-in AC Power Supply, and DC Operation with Optional DC-DC Converter DC-DC Converter DS-1A (option) can be attached to the Transceiver for mobile operation. 15. Wide Variety of Auxiliary Circuits and Devices The Transceiver is completed with a noise blanker circuit, VOX circuit, side tone circuit, marker circuit, built-in speaker. 3-position AGC switch, heater switch, IF OUT terminal and linear terminal. The following devices are available as optional extra: Remote VFO (VF0-820). CW Filter (YG-88C). Digital Display (DG-1A), Transverter (TV-502S). Microphone (MC-50,. Low Pass Filter (LF-30A).

Information

This manual has been written basically for use of model TS-820S. The difference between models TS-820S and TS-820 is that model TS-820S has digital display built-in as against model TS-820 has no digital display built-in. Accordingly, if you have purchased model TS-820 you may skip over the passages concerning digital display.
