Birdies
Birdies are frequencies your scanner uses when it operates. These
operating frequencies might interfere with broadcasts on the same
frequencies. If you program one of these frequencies, you hear only noise
on that frequency.
If the interference is not severe, you might be able to turn SQUELCH
clockwise to cut out the birdie. The most common birdies to watch for are
listed below.
Birdie Frequencies:
31.05 MHz 124.20 MHz
41.40 MHz 134.55 MHz
51.75 MHz 144.90 MHz
113.85 MHz 155.25 MHz
Reception Notes
Reception of the frequencies covered by your scanner is mainly "line of
sight". That means you usually cannot hear stations that are beyond the
horizon. During the summer months you may be able to hear stations in the
30-50 MHz range located several hundred or even thousand of miles away.
This is because of summer atmospheric conditions. This type of reception
is unpredictable but often very interesting!
One very useful service is the National Weather Service's continuous
weather broadcast. These broadcasts contain weather forecasts and data
for the areas around the station, plus bulletins on any threatening
weather conditions. These stations use three frequencies - 162.40,
162.475 or 162.55 MHz. In most areas of the country, you can receive one
of these frequencies.
A Guide To The Action Bands
With the right frequencies programmed into your PRO-Series Scanner, you
can monitor exciting events. With a little investigation, you can find
active frequencies in your community. We can give you some general
pointers, and you can take it from there. Please use caution and common
sense when you hear an emergency call. Never go to the scene of an
emergency. It could be very dangerous.
Find out if there is a local club that monitors your community's
frequencies. Perhaps a local electronics repair shop that works on
equipment similar to your scanner can give you frequencies used by local
radio services.
A volunteer police department or fire department can also be a good source
for this information.
As a general rule on VHF, most activity is concentrated between 153.785
and 155.98 MHz and then again from 158.73 to 159.46 MHz. Here you find
local government, police, fire and most such emergency services. If you
are near a railroad yard or major railroad tracks, look around 160.0 to
161.9 MHz for signals.
In some larger cities, there has been a move to the UHF bands for
emergency service. Here, most of the activity is between 453.025 and
453.95 MHz and between 456.025 and 467.925 MHz.
In the UHF band, frequencies between 456.025 and 459.95 MHz and between
465.025 and 469.975 MHz are used by mobile units and control stations
associated with base and repeater units that operate 5 MHz lower (that is,
451.025 to 454.950 and 460.025 to 464.975 MHz). This means that if you

find an active frequency inside one of these spreads, you can look 5 MHz
lower (or higher) to find the base station/repeater for that service.
Typical Band Usage
The following is a brief listing of the typical services that use the
bands you scanner can receive. This listing helps you decide which ranges
you would like to scan.
These frequencies are subject to change, and might vary from area to area.

Guide To The Action Bands
United States Broadcast Bands
In the United States, there are several broadcast bands. The standard AM
and FM bands are probably the most well known. There are also four
television audio broadcast bands-the lower three transmit on the VHF band
and the fourth transmits on the UHF band.
Frequency Range Allocation
54.0 - 72.0 MHz ........................................... VHF Television
76.0 - 88.0 MHz ........................................... VHF Television

174.0 - 216.0 MHz ......................................... VHF Television
470.0 - 805.75 MHz ........................................ UHF Television
International Broadcast Bands
Several short-wave bands are allocated for international broadcasting
because of the nature of propagation of high frequencies. The bands are
sometimes identified according to the approximate wavelength of the
signals in meters. Your scanner may receive the 11-meter band, from
25.6 - 26.10 MHz.
Typical Band Usage
HF Band (3.0 - 30.0 MHz):
Mid Range: ............................................. 25.00 - 28.63 MHz

Frequency Conversion
The tuning of a station can be expressed in frequency (kHz or MHz) or in
wavelength (meters). The following information can help you make the
necessary conversions.
1 MHz (million)=1,000 kHz (thousand)
To convert MHz to kHz, multiply by 1,000:
9.62 MHz x 1000 = 9620 kHz
To convert from kHz to MHz, divide by 1,000
2780 kHz / 1000 = 2.780 MHz
To convert MHz to meters, divide 300 by the number of megahertz
300 / 7.1 MHz = 42.25 meters
A Note on Image Reception
Radios work by simple mathematics. For example, most tune to a frequency
by mixing that frequency with another (local oscillator) frequency which
is slightly different. This mixing process primarily gives us the two
original frequencies, their sum, and their difference. Well, the radio's
Intermediate Frequency (I.F.) filter normally passes either the sum or
difference frequency, and this is then processed into the sound we hear.
Because nothing is perfect, certain "harmonics" will also get through if
they are strong enough. For example, if a radio's I.F. is 10.7 MHz, we
might be able to tune to a frequency 21.4 MHz (2 x I.F.) above (or below,
depending on the radio's design) a strong signal and hear it! This is more
evident in a double-conversion radio than a triple-conversion radio,
because the triple-conversion radio's 1st intermediate frequency is quite
high. This causes the image to be so far off frequency that it is easy to
effectively filter it out.
So remember that just because a radio doesn't receive something which
another does is not necessarily an indication of a problem. The one radio
may simply not be "tricked" into picking up an image! This rejection of
undesired signals is one reason that a triple-conversion receiver costs
more than a similar dual-conversion model.
You might be interested in finding more out about radio. One good
location to start looking is your local public library. You might also
wish to contact the A.R.R.L., as they are an excellent source of
informative texts on the subject.

Changing the AM/FM Mode
We designed your scanner to automatically select the most common receive
mode for each frequency range. The default settings are:
FREQUENCY (MHz) RECEIVE MODE
30.000 - 54.000 FM
118.000 - 136.975 AM
137.000 - 174.000 FM
380.000 - 512.000 FM
806.000 - 960.000 FM
Although the preset mode is correct in most cases, some harm radio and
military aircraft broadcasts do not receive in the default mode. When the
scanner is not set to the correct receive mode, the broadcast might sound
weak or distorted.
The scanner was designed to automatically select the most common receive
mode for each frequency range. Although the preset mode is correct in
most cases, some ham and military broadcasts do not receive in the default
mode. When the scanner is not set to the correct receive mode, the
broadcast might sound weak or distorted.
To change the mode press AM/FM. AM or FM blinks on the display when you
override the default mode.
If you press AM/FM during a limit or direct search, the scanner no longer
uses the default AM/FM mode for each frequency. The scanner keeps
searching for frequencies in the selected mode and AM and FM blinks on the
display. AM or FM blinks even if the mode of the frequency is the same as
the default setting. To return to the default settings, press AM/FM while
holding down CLEAR.
LIMIT SEARCH
Limit search lets you search for active frequency within the range you select, so you can choose which ones you want to store.
1. Press PROGRAM, then LIMIT. Lo appears on the display.
2. Using the number keys, enter the lower limit of the Frequency range.
3. Press ENTER, then LIMIT Hi appears on the display.
4. Using the number keys, enter the upper limit of the frequency range
and press ENTER
5. Press the up arrow to search from the lower limit to the upper limit,
or the down arrow to search from the upper limit to the lower limit.
6. When the scanner stops press MONITOR to store the freq. in a current
monitor memory.
DIRECT SEARCH
When the scanner is stopped on a frequency, you can search up or down from
the current displayed frequency to find more frequencies you want to
store.
1. Press MANUAL or PROGRAM.
2. Use the number keys to enter the frequency you want to start the
search from, or use the number keys to to enter the channel nunmber
containing the starting frequency.
3. Press MANUAL or PROGRAM.
4. Press the up arrow to search up from the frequency or the down arrow
to search down from the selected frequency.
5. When the scanner stops press MONITOR to store the frequency in a
current monitor memory.
DELAY
Many agencies use a two-way radio system that might have a pause between a
query and a reply. Your scanner's delay feature waits for 2 seconds after
each transmission while scanning or searching.
To program a 2-second delay for any channel while scanning, manually
select the channel and press DELAY until DELAY appears on the display.
When your scanner stops on the channel, it waits for 2 seconds after each
transmission before it resumes scanning.
To program a 2-second delay for any active frequency while searching,

2 of 8 7/29/2007 11:46 AM
press DELAY until DELAY appears on the display. When your scanner stops
on a frequency, it waits for 2 seconds after each transmission before it
resumes searching.
To turn off the programmed delay on any active channel, press DELAY while
the channel is still active. DELAY disappears from the display.
LOCKING OUT A CHANNEL
You can scan channels faster by locking out those that have a continuous
transmission, such as a weather channel.
To lock out a channel while scanning, press LOCK OUT when the scanner
stops on the channel. To lock out a channel manually, manually select the
channel and press LOCK OUT until LOCK-OUT appears on the display.
To remove the lockout from a channel, manually select the channel and
press LOCK OUT so LOCK-OUT disappears from the display.
Notes:
You can still manually select locked-out channels.
You cannot lock out all channels.
PRIORITY
The priority feature lets you scan through the programmed channels and
still not miss an important or interesting call on a specific channel.
To program a stored channel as the priority channel, press PROGRAM, the
desired channel number, and then PRIORITY.
Note:
You can only select one channel as the priority channel.
To turn on the priority feature, press PRIORITY appears on the
display. The scanner checks the priority channel every 2 seconds, and
stays on the channel if there is activity. P appears to the left of
the display whenever the scanner is set to the priority channel.
To turn off the priority feature, press PRIORITY during scanning until
PRIORITY disappears from the display.
USING THE ATT SWITCH
You can set ATT to 10 dB to reduce interference or noise caused by signals
from a strong local broadcast, or to 0dB to increase the reception of weak
signals.
Note:
With the switch set to 10 dB, your scanner might not receive weak
signals.
A GENERAL GUIDE TO SCANNING
Reception of the frequencies covered by your scanner is mainly
"line-of-sight." That means you usually cannot hear stations that are
beyond the horizon.
During the summer months, you might be able to hear stations in the
30-50 MHz range located several hundred or even thousands of miles away.
This is because of summer atmospheric conditions. This type of reception
is unpredictable but often very interesting!
GUIDE TO FREQUENCIES
National Weather Frequencies
161.650 MHz 162.425 MHz 162.475 MHz 162.550 MHz
161.775 MHz 162.440 MHz 162.500 MHz 163.275 MHz
162.400 MHz 162.450 MHz 162.525 MHz
Ham Radio Frequencies
Ham radio operators often broadcast emergency information when other means
of communication break down.
The following chart shows the voice frequencies that you can monitor.
Wavelength (meters) Voice (MHz)
6-meter 50.100 54.000
2-meter 144.100 148.000
70-cm 420.000 450.000
BIRDIES
Birdies are frequencies your scanner uses when it operates. These
operating frequencies might interfere with broadcasts on the same
frequencies. If you program one of these frequencies, the scanner locks

up and you hear only noise on that frequency.
If the interference is not severe, you might be able to rotate SQUELCH
clockwise to cut out the birdie. The most common birdies to watch for are
listed below.
Birdie Frequencies:
32.100 MHz 150.150 MHz 429.050 MHz 810.150 MHz
32.250 MHz 155.500 MHz 434.400 MHz 820.650 MHz

FREQUENCY CONVERSION
The tuning location of a station can be expressed in frequency
(kHz or MHz) or in wavelength (meters). The following information can
help you make the necessary conversions.
1 MHz (million) = 1,000 KHz (thousand)
To convert MHz to kHz, multiply by 1,000:
30.62 MHz x 1000 = 30,620 kHz
To convert from kHz to MHz, divide by 1,000.
127800kHz/1000=127.8MHz
To convert MHz to meters, divide 300 by the number of megahertz.
300/171MHz= 1.75 meters
