TS-830S is the ultimate model of the Kenwood hybrid high frequency
transceivers. It inherited its architecture from previous successful
models, solid state with the exception of the driver and power amplifier vacuum
tubes. It is similar to and was produced at the same time as the TS-530S,
sharing many circuits, but with several additional features. It is a dual
conversion system with separate SSB crystal filters in its two IF amplifiers
making possible variable bandwidth tuning.
The passband can be adjusted continuously from
wide SSB bandwidth to a few hundred Hertz, and selectivity is quite
adequate for casual CW operation. For the CW enthusiast optional CW crystal
filters, either for one IF or both, can be installed easily. The transceiver
also features IF shift and incremental tuning for both receive and transmit, RIT
and XIT, very useful in DX pileups or when your contact is slightly off
frequency. The tunable notch filter nulls annoying heterodynes, and operates at
the IF level rather than the usual, but less effective, audio level. Also
included is an impulse noise blanker that reduces ignition and similar noise.
And while all of the Kenwood hybrids are notable for their outstanding audio
quality, this upgrade's variable compression processing makes it possible to
increase SSB average power incrementally.
The TS-830S covers the amateur HF bands from 160
through 10 meters including the WARC bands with 100 watts peak power output on
CW and 130 Watts peak envelope power output on SSB. The digital frequency
display has a precision of 100 Hz, and WWV can be received at 10 MHz on the 30
meter band for synchronizing frequency and time. Frequently used functions are
readily accessible from the front panel, and retuning when changing bands takes
half a minute or less.
Caveat Emptor: A variant of the TS-830S is the "Gold" version. These
units were introduced in late production and sold at a higher price since they
included both optional CW filters but were otherwise identical to the "non-Gold"
model. Many "Gold" units have had the CW filters removed and sold
separately, so the gold medallion alone is not sufficient to determine if they
are still present.
