Optimizing Scanning Parameters

Move your scanner/antenna to a different location. Sometimes just 12" helps. Digital is especially real fussy.
Get a better antenna. The stock rubber duck/whip antennas are just average quality.

Conventional Scanning

Setting the squelch properly is the easiest and quickest way to receive channels better.

Analog/Digital Trunking

The one thing that frustrated me most with the default settings is the constant blinking of an ID in the display while the scanner was trying to lock on to it.
Here's what I did.

Move your scanner/antenna to a different location. Sometimes just 12" helps. You want that in the upper left of the display to stay there as much as
possible.
For Motorola systems/sites, only enter the

known

control channels/alternate control channels to speed up scanning. You don't need to program the voice

channels.

Turning the squelch down a little will help pull in fringe sites especially for P25 decoding. It will scan multiple sites slower but gives the scanner time to lock
onto the control channels.
Turning the squelch up a little will find the stronger sites faster and therefore move to the next site/system quicker.

If you are having trouble with garbled digital transmissions, try turning AGC on or off for the system or convention frequency.

In the '

Global Settings

' menu:

Turn the

TGRP Pri Int

setting '

Off

' so it will not interrupt trunked activity to check for conventional priority channels (set to default '

').

In the '

Expert Settings

' menu:

Set the

SQ Wait 1

(In-band SQ Timeout/Squelch Time Same Band in the software) down to around

(scan rate).

Set the

EndtoneMot

(Endtone Threshold in the software) down to around

(Digital Detect Timeout/Digital Detect Time in the software) down to around

For Multi-site systems

, program each site into its own Scan List first to see how well the site receives in different locations or conditions. See also

Analyzing Trunking Systems

I would only use the

Multi-Site

Roam

setting if there was only one control channel available at a time to monitor. This may be the case if you are located

on the fringe of several weak sites. Set

Threshold Hi

to around

and

Threshold Lo

to about

for a wider threshold range than the default 95 Hi and 75

Lo. You don't need 95% signal quality to lock on to a site. This will monitor the strongest control channel and look for another only when the signal strength
falls below the 'Threshold Lo' setting.

I don't like the

Roam

setting because it only monitors 1 strong control channel (site) which defeats the whole 'multi-site' concept IMHO. Yes, there may be

different

traffic on any other receivable control channels you have in the system that aren't being monitored. The

Multi-Site

Stat

setting with

Check All CC

set to

will receive more

different

traffic whether you are roaming

stationary. It will monitor

all

receivable sites. My personal experience has given me

the best results by programming each site as one system and putting it in its own Scan List and setting

Multi-Site

Off

for each system. You are usually in

range of only 5-10 sites at any given location anyway so that's only 5-10 Scan Lists. This way you can see which sites are receivable by monitoring one
Scan List at a time and looking for that little in the upper left of the display.

If you don't want to waste that many Scan Lists on one multi-site system, put all the known good receivable sites for each location into one system
assigned to one Scan List, set the

Multi-Site

setting to

Stat

and set

Check All CC

. This will monitor all control channels and sites. Or, a combination

of both methods; put all the

strong

sites in one Scan List and the intermittent or fussy sites in their own list so you can enable those when

conditions/locations are favorable. The ultimate goal is to make your scanner monitor only strong (receivable) control channels.

These are just my suggestions. You will have to experiment with different ways to find what works best for you. Factors like how busy the multi-site system
is, how much traffic you want to listen to on

that

system, and how many other systems you want to listen to will determine the best way for you to setup

each multi-site system.

Tune Search/Analyze Mode

Contents

The scanner's TUNE mode allows you to quickly enter any frequency and monitor that frequency for transmissions, or search up or down from that
frequency for activity. TUNE mode also displays information about trunking control channels and trunked voice channels it finds while tuning and other
information for conventional frequencies depending on the

ADC Cal

setting in the '

Expert Settings

' menu.

TUNE search will always check for and display any CTCSS/DCS/NAC squelch, control channel information, and digital modulation each time it finds an
active frequency.
