Cobra 148 GTL 40-Channel Classic CB Radio
Descriptions:
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.
COBRA 148GTL
has a vastly superior receiver which includes an RF gain control and
noise blanker circuitry effective in both AM and SSB modes., and an
automatic noise limiter effective in the AM mode. The receiver also
features increased protection against cross modulation and strong
adjacent channel signals.
