PLL technology allows accurate frequency derivation without introducing spurious signals which are known to play

9、 havoc with some amateur equip- ment. The single conversion receiver section perfor- mance offers superb protection against unwanted cross- modulation. And now, PLL allows the frequency to remain the same when switching sidebands (USB, LSB, CW) and eliminates having to recalibrate each time. 6-DIGIT

10、 DIGITAL READOUT DG-1A BUILT Along with the easy to read dial, a digital counter display can be employed as an integral part of the VFO readout system. More than just the average read- out circuit, this counter mixes the carrier, VFO, and first heterodyne frequencies to give you your exact frequency

11、. The counter actually figures the frequency down to 10 Hz and the digital display reads out to 100 Hz. Both receive and transmit frequencies are dis- played in handsome, easy to read, Kenwood Blue digits. TS-820 (DC-1A as option) is also available. FULL METERING During receive, a handsome, easy to

12、read meter functions as an S-meter. The same meter displays ALC level, plate current, RF output, and plate voltage during transmit. The five position meter selector switch includes a COMP setting for adjusting the compression level of the built-in speech processor. DIGITAL HOLD A single pushbutton s

13、witch offers the operator unpre- cedented versatility in digital frequency readout. The digi- tal hold circuit will lock the counter and display at any frequency, but will allow the VFO to tune normally. Have you ever wanted to return to a certain spot on the band and have forgotten the frequency? T

14、hat wont happen again with the new digital hold feature on the Kenwood TS-820S. RF MONITOR The built-in monitor circuit allows you to hear your own voice during transmis- sion by sampling the RF si- gnal. This circuit is especially useful for adjusting the RF Processor. NOISE BLANKER The TS-820S use

By employing a special cry- stal filter, it assures unsur- passed efficiency in eliminat- ing unwanted pulse noises such as ignition noise. The TS-820S also incorporates a unique RF spee- This is permanently installed, ch processor.

16、It utilizes a 455 kHz circuit to provide quick time constant compression. This feature is a true RF compressor as opposed to an IF clipper and the amount of compression is adjustable to the desired level by a conve- nient front panel control. DIRI (DR!

19、n, a special 8 pole filter is used to alter the audio frequency response to provide a more comfortable, and easy to copy tone. RF NEGATIVE FEEDBACK To improve the linearity during transmission, RF NFB is applied from the final stage to the driver stage. The use of amplified ALC and so, the RF NFB ha

20、s brought a considerable further improve- ment to the quality of the transmitted signal. IF SHIFT Sometimes called a passband tuning circuit, the IF SHIFT control varies the IF passband without changing the receive frequency. This special feature enables the operator to eliminate unwan- ted signals

21、by moving them out of the pass- band of the receiver. This feature alone makes the TS-820S the pacesetter that it is. I/OX voice-activated microphone circuit is built into le TS-820S with VOX CAIN, ANTIVOX, and OX DELAY controls placed on the front panel ar convenient adjustment any time. RF ATTENUA

22、TOR Easy, one touch activation of the attenuator supplies 20 dB of padding on receive. The switch is conveniently located on the front panel. FINAL AMPLIFIER The TS-820S is completely solid state except for the driver (12BY7A) and the final tubes. Rather than substitute TV sweep tubes as final ampli

23、fier tubes in a state of the art amateur transceiver, Kenwood has employed two husky S-2001A (equivalent to 6146B) tubes. These rugged, time- proven tubes are known for their long life and superb linearity. The input power of the TS-820S is conservatively rated at 160 Watts DC, 200 Watts PEP. The tu

24、bes run cool with the aid of a noiseless fan (standard) mounted on the rear panel. The above tube and power combination minimizes the possibilities of TVI and helps to maintain the Kenwood reputation for excellent audio quality. VERNIER TUNING Precision vernier tuning is incorporated with the plate

25、tuning control to provide a rapid and accurate adjustment during the tune-up. RIT The quick and easy way to vary the receive frequency 5 kHz either side of the VFO frequency. Of course, the effect of the RIT will be displayed by the DC-1A digital counter display. HEATER SWITCH The heaters of the thr

(31 kg) AT-200 AT-200 is an antenna tuner equipped with such functions as an antenna

33、 coupler, throughline wattmeter, SWR meter and antenna selector switch necessary for various kinds of effective operations connecting a transceiver with an antenna. FEATURES AT-200 is an antenna tuner designed for use with the TS-520 and TS-820 series. AT-200 consists of an antenna coupler, a throug

34、h-line RF watt- meter, an SWR meter and an antenna switch. AT-200 is designed to be used on the amateur bands between 1.8MHz and 30MHz. The RF wattmeter has two ranges, 20W and 200W. The antenna switch has four outputs. Two of these are for coaxial fed antennas, one is for a wire antenna and one is

35、for connecting a dummy load. The antenna matching circuit is effective in reducing TV I as it acts as a band-pass filter. AT-200 is also capable of matching your transceiver with a wire antenna such as an inverted-L. Therefore it is possible to enjoy communication on the lower frequency bands. SPECI
