Electra Bearcat III Scanner Operations Manual

Electra Bearcat III Scanner Operations Manual PLDZ-3

The Bearcat III is a table and mobile model, single or dual
band FM monitor receiver providing automatic scanning of 8
channels in one or two of the three Public Safety/Business
Bandsat 30-50mHz, 146-174mHz and 450-470mHz.
Its features include: provisions for one or two plug-in
r-f modules; 8 plug-in crystals in any combination may be
used; high speed automatic or manual scanning; channel
switches to omit scanning of undesired channels; solid state
Light Emitting Diode channel indicators; combination squelch
and sensitivity control; front-mounted 3" x 5" speaker;
external speakerjack; cables for 117Vac or 12Vdc operation;
and operation from a single telescoping or outside antenna.
The most advanced developments in solid state circuitry
are incorporated in this receiver; dual-gate MOS Field Effect
r-f and mixer transistors provide low noise and low crossmodulation.
Single conversion into monolithic quartz crystal
i-f filters reduces spurious responses and radiation and
improves selectivity; linear integrated circuits provide i-f
gain, detection, audio amplification and output; TTL I.C.
multivibrators and gates provide scanning logic; desired chan
nels are scanned with no time lost scanning unwanted
channels.
