GENERAL DESCRIPTION
Your SOMMERKAMP TS-732P transceiver has been désignée! for continous heavy
duty mobile and base Station application. It can be operated with a microphone
and internal speaker or headset, speaker/ microphone combination,
telephoneset
incorporating automatic voice operated transmit/receive Switching, external sélective
calling with automatic answerback and many more.
GENERAL:
The transceiver is designed to operate from either 110/220 Volt AC or 12 Volt
DC powersupply as a base or mobile station.
Its straight forward 32 channel
capabifity allows it to operate on any combination of frequencies within 26 5 and
29.7 MHz by inserting the corresponding xtals and retuning the transceiver if
required. The Xtals in the transceiver are standard 27 MHz CB Xtals with plus
or minus 455 KHz receiver offset. No special synthesiser or IF Xtals are required.
RECEIVER SECTION
The receiver section is designed to receive amplitude modulated (AM/A3) signais
in the 26.965 to 27.275 MHz. (11 meter) citizens band. The unique combination
of low noise Field Effect Transistors (FET),
single conversion,
a combination
of mechanical ceramic, and L/C filters, fully automatic noise limiter and a
hifi
quality speaker amplifier will give you exceptional réception
quality
in
this
fine piece of equipment.
In addition, the above combination of the latest technology provides you with
a sensitivity and unwanted signal rejection and
noise
suppression
available
previously only in space and military communication equipment.
The power supply of the receiver RF. IF and oscillator section is stabilized by an
extreme Sharp cut-off Zener diode to obtain the high sensitivity and unwanted signal
rejection. The fully automatic sériés gâte noise limiter, which virtually cuts off
the audio output during ignition noise puises, is defeatable to make even the
weakest signal audible which otherwise would be eut off by the threshold level of
the ANL switching diode.
The high squelch sensitivity is ac.hieved by using a separate squelch detector and
switching circuit with a carefully balanced hystérésis. The transformerless
hifi
quality audio power amplifier will drive any load between 8 ohms and indefininite
such as internai speaker or externai speaker/microphone or headset combinations
having the above impédances.
The meter indicates the field strength during réception of a signal.
