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 commu-
nications service was opened in 1959. (CB also includes a Class A citizens band
and Class C remote control frequencies.)
FCC regulations permit only ÒtransmissionsÓ (one party to another) rather than
ÒbroadcastsÓ (to a wide audience). Thus, advertising is not allowed on CB
Channels because that is Òbroadcasting.Ó
“Cuts Static coming in, adds Punch going out!”
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 ÒpunchesÓ
your message through the hundreds of thousands of signals that are in the air. At
the same time, SoundTracker system dynamically adjusts the relationship between
the signal and static commonly referred to as noise. This allows CobraÕs
SoundTracker system to significantly reduce the amount of static on all incoming
CB signals. The system can be further optimized when two SoundTracker CBÕs 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
Serial No.
