3INTRODUCTION
Cobra proudly introduces the first Patent Pending technology that dramatically
improves the transmission and reception of CB radio signals.
This revolutionary system reconfigures the transmission signal which allows it to be
transferred more effectively through cluttered airwaves. It literally “punches” your
message through the hundreds of thousands of signals that are in the air. At the same
time, SoundT r ac ker system dynamically adjusts the relationship between the signal
and static commonly referred to as noise. This allows Cobra’s SoundTr ackersystem to
significantly reduce the amount of static on all incoming CB signals. The system can
be further optimized when two SoundTracker CB’s are used to talk to each other.
The end result is a clearer, cleaner sounding reception of signals and more powerful transmissions which
dramatically
improve CB communications.
The 36ST is designed to give you consistent, outstanding performance in virtually
all conditions and situations. To insure you get the most from the Cobra 36ST,
please read this operating guide carefully before using the unit.

THE CB STORY
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 communications 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.”
FCC WARNINGS
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 technical 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.
Nevertheless, an operator of a CB radio station is still required to comply
with the communications act and with the rules of CB Radio Operation.
