Section 1. Introduction And Features - Trio TS-530SP Instruction Manual

SECTION 1. INTRODUCTION AND FEATURES
1.1 KENWOOD TS-530
The TS-530 is highly sophisticated solid state Amateur
band transceiver employing only three vacuum tubes.
Operating on all Amateur bands between 1.8 and 29.7
MHz, this unit is constructed modularly. The TS-530 in-
cludes many built-in features usually found as extras on
other transceivers. Included are VOX. 25 kHz calibrator,
RlT, RF attenuator, and an effective noise blanker. The
TS-530 also includes automatic gain control (AGC), auto-
matic level control (ALC), semi-break-in CW with sidetone,
a speech processor, speaker and built-in AC power supply.
Any complicated electronic device will be damaged if
operated incorrectly. and this transceiver is no exception.
Please read all of the operating instructions before putting
your TS-530 on the air.
1.2 FEATURES
1. Interference-free DX operation
*
TUNABLE NOTCH FILTER
Interference is reduced or eliminated using the built-in
notch circuit. The TS-53O uses an Audio notch filter.
'
lF shift circuit
The lF SHIFT is a circuit to shift lF pass-bandwidth
without changing receive frequency. lt eliminates in-
terference or adjusts receive frequency characteristic
as desired.
*
NARROW/WIDE BAND WIDTH selection and optional
filters for enhanced operation. NARROW or WIDE
CW operation can be selected when using one of two
optional filters:
YK-88C (5OO Hz) or YK-88CN l27O Hzl
NARROW or WIDE SSB operation can be selected
when using the optionalYK-88SN (1.8 kHzlfilter.
2. WARC bands
The TS-53O fully covers the 16O-1Om Amateur
bands, including the new WARC bands of 1O. 18 and
245 MHz. The VFO covers at least 5O kHz above and
below each 50O kHz band. The optional VFO-230 ex-
ternal digital VFO covers about 1OO kHz above and
below each band, for MARS and other applications.
3. All-in-one, compact AC Power supply.
4. Advanced circuit design for improved two-signal
characteristics. Cleverly designed front-end circuit
components and receive circuit system assure excel-
lent two-signal characteristics. Cross-modulation and
blocking are reduced.
5. TX final unit uses 61468's/S2OO1A.
The final transmitting tubes are: two 61468's two
6146B's, 61468's/S2OO/AS for the TS-530SP; on
S2OO1 A for the TS-530D.
Amplified ALC provides clear, strong signals with re-
duced cross modulation.
6. Variable level noise blanker
Conventional fixed level noise blankers are sometimes
less than effective in removing pulsating noise over
weak signals or rejecting strong interference signals.
This variable level noise blanker is equipped to control
the optimum threshold level of the gate pulse ampli-
fier.
7. The speech processor controls the audio compression
level and ALC time constant to increase the average
audio level and transmit power.
8. XIT (Transmit lncremental Tuning) for fine adjustment
of transmit frequency independent of receive fre-
quency.
9. Built-in digital display
Displays accurate frequencies to the 1OO Hz order,
any band or mode.
1O. The controls are arranged on the zinc die-cast front
panel for easy operation.
1 1 . A full variety of accessory circuits are provided:
The TS-530 includes:
VOX circuit (available for Semi-Break in), Marker cir-
cuit, side-tone oscillator, selectable AGC (OFF. FAST,
SLOW) RF Attenuator. CW zero-beat circuit (in the
Tune position), HEATER switch. SCREEN GRID
switch, and built-in speaker.
