Kenwood TS-480HX/480SAT - Manual (Page 5)

The TS-480SAT is
equipped with a built-in
automatic antenna tuner.
The TS-480HX features
two power terminals
for the twin final
section.
AF DIGITAL SIGNAL
PROCESSING (TX/RX)
❚ IF filters (option)
Optionally available for
more intense operations
are 500Hz and 270Hz
band CW narrow IF filters
(YF-107C, YF-107CN),
as well as a 1.8kHz band
SSB narrow IF filter
(YF-107SN). Any two of
these IF filters can be installed inside the transceiver.
AF DIGITAL SIGNAL
PROCESSING (TX/RX)
Thanks to a 16-bit digital signal processor offering
double-precision arithmetic operations (equivalent
to 32-bit processing), a
100MHz clock and 16-bit
A/D & D/A converters,
the TS-480HX/SAT
offers many powerful
features.
❚ Digital noise limiter (DNL)
With three level settings, the DNL is highly effective in
removing even the pulse noise that cannot be eliminated
with conventional analog circuitry and noise blankers. For
extra clarity, however, it can be used in conjunction with a
noise blanker, which removes pulse noise at the IF stage.
❚ Beat cancel (SSB/AM only)
DSP will also cancel out
multiple beats falling
within the AF filter range.
Choose BC1 to remove
weak and/or continuous
beat interference, or BC2
to handle intermittent
beat, like that of a CW
signal.
❚ Noise reduction
NR1 is a line enhanced
filter with 10 level settings
(including auto) — great
for extracting a target
signal. A good choice for
CW operations is NR2
(SPAC), adjustable in 2ms
increments (2~20ms);
it can suppress noise at
the same frequency as
the target signal, allowing
it to pull a weak target
signal out from the
surrounding noise.
❚ TX/RX equalizer
The equalizer offers flat (default), high boost (2 types),
formant pass, bass boost (2 types), conventional and
user* settings, separately for transmit and receive.
*Configurable using the ARCP-480 radio control program.
