FCC LICENSE REQUIREMENT
Donot transmit with your CBunit without an FCC(Federal Communication Commission) Class D Citizens Radio Service
License, or temporary permit.
Youmustapplyfora licensebymailinga completedFCCForm505to
the FCC, GETTYSBURG,PA. 17326.
At the time this User's Guide was published, no fee for Class D
Licenses was required. This is, of course, subject to change in the
future.
Youmay use Form 555-Bas a temporarypermitwhileyourregular
Form505applicationis beingprocessedbythe FCC. .
Transmittingwithouta license or temporary permitis illegal,but you
can listen to (or monitor) all channels without a license. You are
!
required to be familiar with and understand Part 95 of the FCC
Rules when transmitting.
General requirements foran FCC license are that you must be 18 or
over and a U.S. citizen. Anyone 12 or over in your household can
operate the CBas longas the FCCrulesand regulationsarefollowed.
YourFCC station license willshow your call "letters" (or "sign").
Five or more units may be operated under a single FCC station
license. Ifyou plan to have morethan fiveunits, specifyquantityon
FCCForm505. .
FORMS PACKED WITH CB

SPECIFICATIONS
GENERAL
CHANNELS: AM-40 channels. PLL digital logic channel synthesizer
circuitry. 40 USB and 40 LSB channels.
POWER REQUIREMENT:Consumption - 34.5 watts. Currentdrain -
2.5 amps (Max at 12 watts PEP) at 13.8-volt DC.
POWER SUPPLY: 12 volts DC nominal (positive or negative ground),
or 120 volts AC
-60 Hz.
SEMICONDUCTORS: Integrated circuits, transistors, FET (field
effect transistor), diodes, and 2 crystal filters -one in the AM IF and
one in SSB IF.
Crystal filters differ from LC or ceramic filters in that they are more
selective and reduce unwanted incoming signals.
