TRANSMITTER & MODULATOR SECTION:
The transm itter section is designed for continous heavy duty transmission of
amplitude modulated (AM /A3) signais in the 26.965 to 27.275 MHz. (11 meter)
citizens band.
The transm itter consists of crystal controlled osciilator. The output of this osci-
llator is amplified in a dass A buffer followed by a tuned filter, and a highly
efficient collector-modulated dass C driver and power output stage, coupled by
séries and pi-matching filte rs to the antenna jack.
The modulator consists o f an input audio filter, integrated pre-and power amplifier
and modulation transformer. This gives you the lowest possible modulation
distortion and up to 100% modulation. The input is designed for 500 to 10K ohm
dynamie microphone or 8 ohm speaker/microphone combination with a 1K ohm
resistor in sériés.
RECEIVE/TRANSMIT SWITCHING:
The receive/transmit switching is done by a single pole, single throw switch in the
microphone and a combination of NPN and PNP switching transistors.
METER:
The combination meter provides you with the following functions:
During receive mode.......it indicates the incoming signal strength.
During transmit m ode--it indicates the output powerr.
AC POWERSUPPLY
The AC powersupply consists of the heavy duty power transformer, a 4 diode füll
wave bridge rectifiers and a heavy duty voltage stabiliser for 13. 5 Volt for the
receiver and transm itter sections.
DC POWERSUPPLY
This transceiver is designed to operate only from a 12V. DC negative grounded
powersupply.
