Guide To The Action Bands - Realistic PRO-2025 Owner's Manual

GUIDE TO THE ACTION BANDS
With a little investigation, you can find
the active frequencies in your commun¬
ity to monitor exciting events. We can
give you some general pointers on find¬
ing these frequencies and you can take it
from there. Please use caution and com¬
mon sense when you hear an emergen¬
cy call. Never go to the scene of an
emergency. It could be very dangerous.
Find out if there is a local club that moni¬
tors your community's frequencies. Per¬
haps a local electronics repair shop that
works on equipment similar to your
scanner can give you channel frequen¬
cies used by local radio services. A vol¬
unteer police department or fire depart¬
ment employee can also be a good
source for this information.
As a general rule on VHF, most activity
concentrates between 153.785 and
155.98 MHz and then again from 153.73
to 159.46 MHz. Here you find local gov¬
ernment, police, fire, and most other
emergency services. If you are near a
railroad or major railroad tracks, look be¬
tween 160.0 to 161.9 for signals.
In some larger cities, there has been a
move to the UHF bands for emergency
services. Here, most of the activity is be¬
tween 453.025 and 453.95 MHz and
again between 456.025 and 459.95
MHz.
In the UHF band, mobile and control u-
nits associated with base and repeater
units operate between the frequencies
of 456.025 and 459.95 MHz and again
between 465.025 and 469.975 MHz.
The repeaters operate 5 MHz lower than
the base and mobile units (that is,
451.025 to 454.95 MHz 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, as the case may be) to find
that radio service.
Frequencies in different bands are ac¬
cessible only at specific intervals. How¬
ever, the frequencies that you can store
into your scanner's memory are in 5 or
12.5 kHz steps. Your scanner automati¬
cally rounds the entered frequency
down to the nearest valid frequency. For
example, if you try to enter a frequency of
151.473, your scanner accepts it as
151.475.
