Although the model numbers
are not sequential, the TS-530S is actually an upgrade to the TS-820S. It
incorporated additional features and
performance improvements while retaining the hybrid combination of solid state
technology and power vacuum tube
technology to take advantage of the best of both.
In addition to the 160, 80, 40, 20, 15, and 10 meter bands, it covers the 30, 17, and 12 meter bands allocated in the mid 1980s by the
World Administrative Radio Conference (WARC). WWV can be received at 10 MHz
on the 30 meter band for
frequency and time synchronization, and provision is made for installing an
auxiliary band. Rated RF power output is 100 Watts CW and 130 Watts peak
envelope SSB power. The TS-530S has a more reliable digital frequency display with 100 Hz
resolution. Using a very stable VFO and phase locked loop (PLL) heterodyne
oscillator, its single conversion architecture reduces in-band spurious
responses (birdies) and provides exceptional image rejection. It is a bit
smaller and lighter than its TS-520(S) and TS-820(S) predecessors and is very
similar to the TS-830S, sharing much of the same circuitry. It features
receive incremental tuning (RIT), transmit incremental tuning (XIT), and IF
Shift which in combination are useful during DX pileups, when your contact is
slightly off frequency, or when there is nearby interference. It also has an
effective impulse noise blanker. The
Kenwood hybrids are noted for their outstanding audio quality, and this upgrade
includes improved compression processing to increase SSB average power without
loss of intelligibility.
Normally powered from
120 Volt or 240 Volt power mains, an optional 13.8 Volt DC power module can be
