In the United States, there are several broadcast bands. The standard AM
and FM bands are probably the most well known, and you can monitor the FM
band on the scanner. There are also four television audio broadcast bands
- the lower three transmit on the VHF band and the fourth transmits on the
UHF band. You can monitor all three of the VHF bands and the UHF band.
Frequency Range Allocation
54.0 - 72.00 MHz VHF Television
76.0 - 88.00 MHz VHF Television
88.0 - 108.00 MHz Standard FM
174.0 - 216.00 MHz VHF Television
470.0 - 805.75 MHz UHF Television
International Broadcast Bands
Several shortwave 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.
Frequency Range Band
(in MHz) (in meters)
25.60 - 26.10 11
Typical Band Usage
HF Band (3.00-30.0 MHz)
Mid Range, Citizens Band ....................... (25.00 - 28.00 MHz)
Base Stations 451.025 - 454.950 MHz
Mobile Units 456.025 - 459.950 MHz
Relay Repeater Units 460.025 - 464.975 MHz
Remote Control Stations 465.025 - 469.975 MHz
NOTE: Remote control stations and mobile units operate at 5 MHz higher
than their associated base stations and relay repeater units.
FREQUENCY CONVERSION
The tuning location of a station can be expre ssed 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 divided by 1000 = 2.780 MHz)
To convert MHz to meters, divide 300 by the number of megahertz.
(300 divided by 7.1 MHz = 42.25 meters)
PRO-2035 1000-Channel Programmable Home Scanner
(200-0460) Care and Maintenance Faxback Doc. # 16918
The Radio Shack PRO-2035 1000-Channel Programmable Home Scanner is an
example of superior design and craftsmanship. The following suggestions
will help you care for the scanner so you can enjoy it for years.
Keep the scanner dry. If it gets wet, wipe it dry immediately.
Liquids can contain minerals that can corrode the electronic circuits.
Use and store the scanner only in normal temperature environments.
Temperature extremes can shorten the l ife of electronic devices and
distort or melt plastic parts.
Handle the scanner gently and carefully. Dropping it can damage
circuit boards and cases, and can cause the scanner to work improperly.
Keep the scanner away from dust and dirt , which can cause premature
wear of parts.
Wipe the scanner with a damp cloth occasionally to keep it looking
new. Do not use harsh chemicals, cleaning solvents, or strong
detergents to clean it.
Modifying or tampering with the scanner's internal components can cause a
malfunction and might invalidate its warranty and void your FCC
authorization to operate it. If the scanner is not operating as it should,
take it to your local Radio Shack store for assistance.
You can connect an optional external speaker with a 1/8 -inch plug to the
scanner. Use an 8-ohm external speaker capable of handling over 2.5 watts
of power (such as Radio Shack Cat. No. 21 -549).
Insert the speaker's plug into the EXT SPKR jack on the back of the
scanner.
NOTE: Plugging in an external speaker disconnects the scanner's internal
speaker.
CONNECTING HEADPHONES
You can connect an optional pair of headphones with a 1/8 -inch plug to the
scanner. Use monaural headphones (such as Radio Shack Cat. No. 20 -210).
Insert the headphones' plug into the headphone jack on the front of the
scanner.
NOTE: Plugging in headphones disconnects the scanner's internal speaker.
Listening Safely
To protect your hearing, follow these guidelines when you use headphones.
Set OFF/VOLUME to the lowest setting before you begin listening. After you
put on the headphones, adjust OFF/VOLUME to a comfortable level.
Do not listen at extremely high volume levels. Extended high -volume
listening can lead to permanent hearing loss.
Once you set OFF/VOLUME, do not increase it. Over time, your ears adapt to
the volume level, so a volume level that does not cause discomfort might
still damage your hearing.
CONNECTING A TAPE RECORDER
You can connect an optional tape recorder to your scanner to record
transmissions. To record from the scanner, you need a tape recorder with a
microphone jack (such as Radio Shack Cat. No. 14 -1151). Also, you need a
connecting cable with a phono plug and a 1/8 -inch plug (such as Cat. no.
42-2461).
1. Insert the connecting cable's phono plug into the TAPE OUT jack on the
back of the scanner.
2. Connect the other end of the connecting cable to your tape recorder's
microphone jack.
Follow the instructions provided with your tape recorder to record
transmissions while the scanner is on.
PRO-2035 1000-Channel Programmable Home Scanner
(200-0460) Features Faxback Doc. # 16908
The Radio Shack PRO-2035 1000-Channel Programmable Home Scanner lets you
in on all the action! With its convenient rotary tuner and keypad, you
can quickly tune to over 196,000 frequencies that include those used by
police and fire departments, ambulance services, aircraft communications,
amateur radio services, transportation services, Citizen's Band and
commercial FM and television broadcasters. You can select up to 1,000
channels to scan and you can change your selections at any time.
The secret to the scanner's ability to scan so many frequencies is its
custom-designed microprocessor - a tiny, built-in computer.
The scanner has all these special features.
Hyperscan - lets you scan and search up to 50 channels
or steps per second.
Weather Band Key - scans ten pre-programmed weather
frequencies to keep informed about current
weather conditions.
Ten Channel-Storage Banks - you can store 100 channels in each bank to
group channels so calls are easier to
identify.
Monitor Memory - temporarily saves up to 100 frequencies
located during a frequency search, letting
you move selected frequencies to permanent
channel storage later.
Priority Channel - you can set the scanner to check every 2
seconds so you do not miss important calls.
Auto Store - quickly finds and automatically stores
active frequ encies in channels, then
searches for additional active frequencies
while skipping previously stored channels.
TAPE OUT Jack - lets you connect an optional tape recorder
to the scanner to record transmissions.
Rotary Tuner - lets you manually tune and select desired
frequencies or channels.
Two-Second Channel Scan Delay - delays scanning for 2 seconds before moving
to another channel so you can hear more
replies.
Memory Backup - keeps channel frequencies stored in memory
for up to 3 mon ths during a power loss.
Lock-Out Function - keeps selected channels from being scanned,
so you can skip over busy channels.
Direct Frequency Search - lets you scan for new and unlisted
frequencies.
Sound Squelch - keeps the scanner from stopping on
frequencies with only a carrier signal and
no voice or other sound, so you can hear
calls instead of static.
Backlit Display - makes it easy to view and change
programming information.
Two Power Options - let you power the scanner from standard AC
power (with the supplied AC power cord), or
your vehicle's battery (with an optional DC
cigarette lighter power cord).
The PRO-2035 scanner can receive all of these bands:
The scanner can receive these pre-programmed weather channels:
161.650 MHz
161.775 MHz

Reception of the frequencies covered by the scanner is mainl y "line-ofÂsight. 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!

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 monit or:
Wavelength (meters) Voice (MHz)
10 - meter 28.300 29.700
6 - meter 50.100 54.000

Birdies are frequencies the 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. These are the most common birdies to
watch for:
NOTE: Depending on the temperature of some of the scanner's components,
you might hear birdies on frequencies slightly above or below the
frequencies listed here.

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 comm on 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 yo ur 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 ther e. 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 conce ntrated 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 an d 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.
