conditions before the media or emergency
management officials announce them to the
general public.
SAME and All Hazards Weather Alerting – Your
scanner can alert you to severe weather and other
hazards in the specific areas that you select. Your
scanner can check your local NOAA weather
frequency periodically, even while scanning, and
alert you when an All Hazards alert occurs.
Multi-System Trunking – Scans most common
trunked radio system signaling formats, including
Motorola, EDACS, LTR and P25 trunked radio
networks. Both talkgroup and individual call
monitoring are supported.
Automatic Adaptive Digital Tracking – When
monitoring P25 digital systems, instantly adapts
the digital decoder to the digital modulation
format of the transmitted signal, then analyzes the
signal over 50 times each second and adapts to
any subtle changes caused by multipath or fading.
No cumbersome manual adjustments are required.
Digital AGC – Instantly compensates for low user
audio levels that are common on digital systems.
LTR Home Repeater AutoMove – Takes the
guesswork out of programming LTR trunking
systems when the home repeater order is not
known. Enter the LTR system frequencies in any
order, and the PRO-106 will automatically move
the frequencies to the proper home repeater
slots as transmissions are received on the system.
Subaudible Squelch Decoder – CTCSS and
DCS subaudible squelch coding is processed
by the same powerful DSP chip that is used for
P25 digital decoding. Provides fast and reliable
decoding of subaudible squelch signaling with
squelch tail elimination.

Signal Stalker II – Quickly sweeps the scanner's
frequency ranges for transmissions from nearby
sources.
P25 NAC Functionality – P25 Network Access
Code (NAC) is used to provide selective squelch
operation on conventional digital channels.
Your PRO-106 will detect the NAC that is being
used on a P25 conventional digital channel,
and allow you to program NAC codes to block
transmissions that do not have a matching NAC,
including analog traffic on the same frequency.
Alert LED – Programmable tri-color LED can be
configured to illuminate or flash when certain
objects are active. Eight user-defined colors and
brightness levels can be specified from thousands
of possible combinations.
Audible alarms – Programmable audible
alarms can be configured to sound when certain
Scannable Objects are active. Can be used in
conjunction with, or separately from, the Alert
LED described above.
High Speed PC Interface – Use a USB Scanner
programming cable for full duplex mode at 6
times the speed of previous scanner models for
PC transfer and 8 times the speed of previous
models for radio to radio cloning. High speed
scanner programming cables are available at your
local RadioShack store or RadioShack.com.
Real-time Signal Strength Indicator – Shows
relative strength of received signals.
IMPORTANT NOTICE: The PRO-106 Digital
Scanner will not receive encrypted radio
communications, or radio transmissions that
utilize ProVoice digital modulation.
