Description: 2m ALL MODE TRANSCEIVER
Informations:
                                    1. The Mode! TS-700A is a fully solid-state, all-mode
amateur band transceiver designed to provide high quality
communications on SS8. FM, AM and CW
modes.
2 Basically engmoered for fixed station operation but is
also used for mobile station operation because of the
employment of AC/DC two-way power system
3. The single and double conversion type transceiver
incorporates its own built-in VFO that continuously covers
tho frequency range of 1440 00 to 148.00MHz in 4 bands
Repeater operation is also possible in tho 146MHz and 147MHz
bands. Tho repeater frequency is shifted at both NORMAL and
REVERSE positions of tho repeater knob.
4 A newly developed two-speed dial mechanism facilitates
tuning MAIN TUNING knob (inner) for closer tuning covers a
change of 25kHz by one complete rotation, and QUICK TUNING
knob (outor) covors
o change of 100kHz similarly. You can tune in quickly with
pin-point accuracy This feature Is very useful in receiving
SSB signals
5 The mam dial is graduated at 1kHz intervals and provides
accurate readings up to 100kHz. while the sub dial is
graduated at 50 and 100kHz intervals for reading frequencies
up to 1MHz per rotation
6. A total of 44 fixed channels (1 I channels for each band)
for all-mode operation including repeater operation. All tho
necessary crystal oscillator elements arc available as
optional accessories Each of working channels can be
visually checked by the KENWOOD's unique channel indicator
7 A noise blanker (NB) circuit of the type normally found in
many other HF products of our make is included to eliminate
pulse noise such as ignition noise.
8. For improved FM-mode operation, a squelch circuit
combined with a noise detector circuit and Schmidt circuit
is added to the FM unit.
9. A tuner which uses a voltage variable capacitor is built
in the receiver RF stage to minimize cross-talk and spurious
interference, and a high "Q" tuning circuit in the antenna
input stage for excellent selectivity.
10 A balanced-type mixer circuit is adopted for the
pre-mixer and heterodyne mixer to assure improved rejection
of spurious signals during transmission.
11 Tho repeater frequency for transmission or reception can
bo inverted (NORMAL REVERSE) with one finger action. Tho
adoption of tono burst system permits tho tone signal to
activate the repeater circuit automatically for transmission
(FM-mode only).
12 Tho IF stago includes a 6-ulomeru crystal filter The
built m wido and narrow band ceramic filters provide
outstanding selectivity during FM reception.
13 Tho employment of threshold typo RF gain control assures
excellent S/N ratio at all times during reception of SSB signals
14 Speaker output is free from distortion because of the use
of amplification type AGC circuit. Signals transmitted are
accompanied by little or no splutter and free from
distortion thanks to the adoption of ALC circuit The AGC
circuit comprises such time-constant element that this
constant is "slow" in SSB mode but "fast" in FM. AM or CW mode
15. The built-in marker signal circuit enables you to
calibrate the tuning dial precisely at 100kHz intervals. By
setting the CALIBRATE switch to ON. the receiver RF input
circuit is disabled, thus permitting frequency calibration
without being disturbed by external signals.
16. The unique "S" meter Ipatent pending} provides accurate
reading without causing "scale-out'' even when unusually
strong FM signal comes in. By manipulating the center meter
switch, this meter functions as a center meter for pin-point
tuning of FM stations
17 VOX operation is also available The transceiver has
provision for connection of VOX-3 obtained from KENWOOD as
optional accessory
18. Tho ON AIR lamp lights up when the transceiver shifts
into transmitting state.
19. Tho built-in RIT circuit is very useful during
reception, particularly in SSB and CW modes It is designed
to bo used for both VFO and fixed channel operations.
20. Besides tho built-in oval spoakor {9cm by 6cm), an
external speaker can bo used by connecting it to tho spoakor
terminal provided on tho transceiver.
21 The transceiver operates on AC 120/220V or on DC 13.8V It
includes DC voltage multiplier of our own development,
contributing much to tho space-saving design of the model
22. Significant improvements are embodied in the panel
design for making this transceiver much easier to control
and use. Dials and knobs are of more advanced typo in visual
and functional senses Meter illumination arid pilot lighting
are included assuming nighttime use of the transceiver
23. Visual aspects are taken as an important criterion in
the designing of this transceiver. Mechanical features too
have been treated similary, with particular emphasis on
their reliability.
24 For assuring easier access to the internals, the
transceiver enclosure or case is in two parts, complete with
special mechanical details to allow the front control panel
to be detached. The final unit is also arranged so that it
can be removed from the rear panel.
25 A carrying strap is provided for convenience of carrying
the transceiver.
26. A high quality microphone is included among the standard
accessories.
