Weather Channels feature a repeating loop of weather related information,
including watches and warnings. Special alarm tones are used to
trigger weather radios when severe weather strikes. In many locations,
you can receive more than one weather channel. Search for the
strongest signal and monitor that station. |

Maintenance frequencies are used by the local wireline phone companies
to maintain communication facilities. 35.16 MHz is for base stations
and is paired with mobile radios on 43.16 MHz. 151.985 MHz is
for base stations, or more likely a repeater system, with mobile
input on 158.34 MHz. It's rare to hear activity on the low band
channels, but this can be a fun channel to monitor for skip. VHF
is still somewhat active, but most telcos have relocated to the
UHF band and use a network of hilltop repeaters. |

Wireless
microphone channels are used in churches, auditoriums, concert
halls, schools and other facilities where a wireless mic would
be handy. At larger shows, you will find many individual microphones
on the air, all on different frequencies, and you can pick up
some very interesting conversations!
Many
times, these mics are left on even though the overhead sound
system is not relaying the audio to the crowd. These frequencies
ARE NOT illegal to monitor, although they are very low power
and you'll have to be close by to pick them up. Also, most of
these frequencies are outside the range of most scanners. A
special receiver is needed to monitor them.

GMRS
is the former "Class A" Citizens Radio Service, designed
for private citizens to have UHF-FM frequencies for personal
use. All licensees must be individuals -- a business cannot
be authorized on these channels. In some locations, groups of
licensees will go together to purchase and maintain a hilltop
repeater station which is used by all members. In other situations,
individual licensees maintain small base stations at their homes
and mobile radios in vehicles.
Although
never wildly popular around the country, GMRS has a loyal following
in some areas but is being replaced by the low price and growing
nationwide reliability of cellular telephones. The 462.675 and
467.675 MHz repeater pair is designated for emergency and travellers
assistance communications. 462.5625 MHz is a low power (half
watt) channel shared by GMRS and the Family Radio Service. By
gentlemen's agreement, this channel is designated as the emergency
calling channel for search and rescue and wilderness survival.

Family
Radio Service (FRS) is an UNLICENSED service of low power UHF
walkie-talkies. If you've seen two or more "professional
FM quality" portable radios that promise you can "talk
up to two miles" being sold at Wal-Mart or a hardware
store, it's probably a couple of FRS units.
Families
use these radios when the kids are outside playing, or when
hiking and camping, or other outdoor recreational use. Although
it's not the intended use, many businesses are picking up FRS
units to use in the warehouse, or throughout the store, or between
employees when working away from the main office.
These
are very low powered radios and you'll have to be close by to
monitor the communication. 462.5625 is FRS Channel 1, and is
the designated emergency call channel for someone lost in the
wilderness. Wilderness survival teams, national park rangers
and search and rescue groups advocate monitoring this channel
at the top of every hour to listen for calls for help.

The
CB Radio Service uses AM modulation and is generally not receivable
on a scanner. Special multi-mode receivers are able to pick
up AM and Single Sideband (SSB) radio transmissions, or you
could just buy a CB radio and listen there.
The
CB Radio Service was created in 1958 for local personal and
business communications, but became a popular hobby in the 1970's
(much like the internet is today). CB frequencies are very prone
to interference, and long distance "skip" signals
can disrupt local communication. Although forbidden by the FCC,
it's possible to talk all over North and Central America on
the CB radio channels under certain atmospheric conditions.
CB radio is a favorite mode of communication for professional
truck drivers and motorists travelling the open highways.

Marine
Radio frequencies are used by boats and certain shore facilities.
There is no rhyme or reason to the channel numbering system
-- it's a hodge-podge list of numbers in no particular order
with many missing channels. Note that Channel 16 (156.80 MHz)
is the national call channel and is designated for emergency
communication.
Commercial
frequencies are normally for barges, oil rigs, etc. and these
is normally a base station at the dock or marina. Channels 24-28
and 84-88 are for ship to shore radiotelephone service. As you
might imagine, cellular telephone service has a huge impact
on STS radio traffic, and you may not find communication on
these frequencies in most locations.
Because
marine radios are so inexpensive (when compared to commercial
grade VHF radio equipment), you may occasionally find a "bootleg"
business, taxicab service, tow truck or local government operation
on a marine frequency, especially in locations that are somewhat
removed from commercial waterways. The FCC takes a dim view
of this illegal operation, and fines can be in the $10,000 per
violation range ...
