Cobra Electronics Cobra 148 GTL - Manual (Page 2)

Section I Introduction
FREQUENCY RANGE
The COBRA 148GTL transceiver represents one of the most advanced SSB/AM two-
way radios ever designed for use as a Class D station in the Citizens Radio Service.
This unit features advanced Phase Lock Loop (PLL) circuitry, which is used in the AM
mode and in the upper and lower single sideband modes, providing complete cover
age of all 40 channels shown below.

The COBRA 148GTL has a vastly superior receiver which includes an RF gain con-
trol and noise blanker circuitry effective in both AM and SSB modes., and an auto-
matic noise limiter effective in the AM mode. The receiver also features increased
protection against cross modulation and strong adjacent channel signals.
To obtain maximum performance please read carefully the descriptions and oper-
ating instructions in this manual.

The Citizens Band lies between the shortwave broadcast and 10-meter Amateur
radio bands, and was established by law in 1949. The Class D two-way communi-
cations service was opened in 1959. (CB also includes a Class A citizens band and
Class C remote control frequencies.)
FCC regulations permit only “transmissions” (one party to another) rather than
“broadcasts” (to a wide audience). Thus, advertising is not allowed on CB Channels
because that is “broadcasting.”
NOTICE:
Replacement or substitution of transistors, regular diodes or
other parts of a unique nature, with parts other than those
recommended by Cobra, may cause violation of the techni-
cal regulations of Part 95 of the FCC Rules, or violation of
Type Acceptance requirements of Part 2 of the Rules.
Citizens Band (CB) Radio operators are no longer required to
obtain an FCC license to operate their CB equipment or
provide station identification.
An operator of a CB radio station is required to comply
with the communications act and with the rules of CB
Radio Operation.
