Sound clarity is measured by the ratio
of the signal level to the noise level.
The higher the signal-to-noise ratio,
the better the sound.

How SoundTracker
TM
Works
On Reception - “Cuts noise coming in”
With a normal CB, distant signals fall below
the squelch level and are unintelligible. With a
SoundTracker
the squelch level and are unintelligible. With a
SoundTracker
TM
CB, the noise level is cut up to
90%, which increases the signal-to-noise ratio
and dramatically improves signal clarity. This also
allows you to significantly reduce the squelch
level, which greatly expands your listening range.

On Transmission - “Strengthens signals going out”
A SoundTracker

CB strengthens the transmit
signal by more effectively using the available RF
power output of the CB. The result is improved
transmission signal clarity and an expanded
