The General Mobile Radio
Service (GMRS) is a land-mobile radio service
available for short-distance two-way
communications to facilitate the activities of
an adult individual and his or her immediate
family members, including a spouse, children,
parents, grandparents, aunts, uncles, nephews,
nieces, and in-laws (47 CFR 95.179). Normally,
as a GMRS system licensee, you and your family
members would communicate among yourselves over
the general area of your residence or during
recreational group outings, such as camping or
hiking.
The FCC Grants 5-Year
Renewable Licenses For GMRS Systems. The
individual licensee is responsible for the
proper operations of the licensed GMRS system at
all times.
A GMRS Operator License Is
Available In The U.S. For Free. Canada
Requires No License. GMRS 2-Way Wireless
Radios Generally Transmit At 1 To 5 Watts, And
May Have Detachable Antennas.
What Are The GMRS
Channels?

1 Frequency 462.5625 MHz (Same
Channel-To-Channel Communicating)
2 Frequency 462.5875 MHz (Same
Channel-To-Channel Communicating)
3 Frequency 462.6125 MHz (Same

What Is CTCSS?
Simple, CTCSS Stands For
'Continuous Tone-Coded Squelch System'; A
Electronic Circuit Designed To Filter Out
Desired Transmissions And Block Undesired On A
Shared Wireless 2-Way Radio Channel.
CTCSS Filters Out
Non-Desired Channel Transmissions (General
Channel Users) From The Reception,; Only
Receiving A Transmissions From A User With The
Same Set CTCSS Code. This Is Very Useful
In Areas Where Channels Are Over Used.
Situations Like A Fly-In, Fair, Races, Special
Events Are Places For Using The CTCSS Filtering.
Note, When The CTCSS Filter
Option Is Used, The Transmission Is Still Hear
By Anyone On That Channel. However, The
People Using The Same CTCSS Setting, Will Enjoy
Only Hearing Each Other, While The CTCSS Filters
Out The Rest Of The Undesired transmissions On
That Channel. |
