MONITOR • Built-in monitor circuit allows you to hear your own voice by sampling the RF signal Especially useful for adjusting the RF Processor.

Wl -Afc TheTS-820 uses an efficient noise blanker circuit, another Kenwood exclusive. A special crystal filter assures unsurpassed efficiency in eliminating unwanted pulse noises.

Kenwood's well deserved reputation for fine craftsmanship and superb performance has never been more evident than in theTS-820. As a result of a host of innovative features being brought together, the 820 offers a degree of versatility, performance and pleasure second to none.

The Kenwood TS-820 is destined to be the world's new standard of excellence in amateur radio for years to come ... a true "Pacesetter".

The VFO-820 is a solid state remote VF0 designed exclusively for use with the Kenwood TS-820 Pacesetter. The VF0-820 has its own R IT circuit and control switch It is fully compatible with the optional digital display in the TS-820 The perfect extra to any Pacesetter station.

digital holt A single pushbutton switch offers the operator unprecedented versatility The digital hold circuit will lock the counter and display at any frequency, but will allow the VFO to tune normally. Ever wanted to return to a certain spot on the band and forgotten the frequency? That won't happen again with the new digital hold feature on the Kenwood TS-820.

circuit provides quick time constant compression using a true RF compressor as opposed to an IF clipper. Amount of compression is adjustable to the desired level by a convenient front panel control.

The IF SHIFT control varies the IF passband without changing the receive frequency. This "IF shift" control is located on the front panel and provides excellent unwanted signal reject control or "pass band tuning." The 820 moves the signal across the IF pass band not the pass band across the signal.

160 METERS • Full band covafiigti employs the Ibtbsi phase lock loop circuitry The single conversion receiver section performance otters 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.
