Your new Sommerkamp TS-340 DX is a Professional quality Citizens Band Transceiver designed to
operate on either AM, Lower Single Sideband (LSB) or Upper Single Sideband (USB). It has many
innovative engineering and user functïons. Among them, a Sommerkamp plus feature is an amplified
AGC circuit, built in to your TS-340. This expands the range of a normal AGC circuit by many
times, and is usually found only in the most expensive sets. Your amplified AGC will enable you to
hear clearly, even a very weak distant signal, and still allow you to hear a unit close by without
overload. The PLL (phase lock loop) frequency Synthesizer is the heart of the TS-340 DX's rock
steady frequency control. The PLL is self compensating for frequency d rift, keeping your TS-340 DX
on center channel, every channel. Careful reading of this instruction manuał before operation is
essential for proper operation and prévention of damage.
PACKING
This unit has been especially protected for shipment. Open the carton carefully to avoid damage.
Examine the unit for any visible damage. If the transceiver has been damaged in shipment, save the
box, and packing material, and n o tify the transportation company.
RECEIVER
Sensitivity o f less than a 1/2 of a microvolt on SSB and AM. A tuned RF stage pulls in even the
weakest signais.
A deluxe filte r on SSB provides the highest degree of selectivity and rejection of unwanted adjacent
channel signais. Ceramic Filters for AM réception deliver over 70 db adjacent channel rejection.
Additional receiver features include: variable squelch, clarifier control, integrated circuit audio
preamplifier stage, metering automatic noise eliminator.
TRANSMITTER
High efficiency is obtained through use of select components and sophisticated engineering design.
An ALC circuit is employed in the SSB mode to provide maximum "Talk Power" w ithout distortion.
The SSB signal is
by use of an integrated circuit balanced modulator and PLL
Synthesizer, to keep you on center channel, every channel. Electronic switching is employed for
dependability.
POWER SUPPLY
Either Positive or Negative ground 12 Volts DC (13.8 VDC E!A) is built in.
