License Free Frequencies
There are several sets of frequencies open to license free operation, meaning no license is required.
49 Mhz
The 49 Mhz frequency
range is popular due to the abundance of equipment available in this frequency
range. These are typically found in the form of kid's "walkie
talkies", although other more professional gear is available. Typical gear
available includes both handheld radios and radios worn on your belt with a
headset. There are not too many base radios available, although sometimes people
will convert old ham equipment to operate here. These sets
typically require large antennas. Other users of
these frequencies include baby monitors and cordless phones. Power output
is limited to 300mw.

Multi-Use Radio Service (MURS)
The MURS frequencies lie in the VHF band. There is a limit of 2 watts output, but external antennas can be used. Some base stations are available. Commercial equipment can easily be adapted to this band and the quality of of the radios is typically better than that of 49 mhz or FRS. The MURS frequencies are:
- #1 - 151.820
- #2 - 151.880
- #3 - 151.940
- #4 - 154.570
- #5 - 154.600
Although there is no such thing as "typical range", these radios have the potential of reaching farther than FRS and 49 mhz due to their 2 watt power limit and the characteristics of VHF signals. There is also no limit on the emission mode of these radios, meaning you can do FM or digital communications. A good source of radios for this band is Ebay. Radio Shack used to sell MURS radios, but I believe they closed them out.

Family Radio Service (FRS)
FRS
frequencies lie in the UHF band. They are low power radios, typically handheld.
The price range varies quite a bit from $20 for a low end handheld to well over
$150 for the more feature-packed models. The power limit is 500mw, severely
limiting the usability of this service. It is mostly used by families, as the
name implies. No removable antennas are allowed. There are some base models,
which have antennas attached to them. The antennas on the radios are typically
small and most FRS radios allow you to select different "Privacy
Codes" (aka "PL" or CTCSS) and often come with the ability to
"page" another user so they can keep the radio on without hearing
everyone talking, until they are needed. Many FRS radio are actually
dual-service radios, containing frequencies for both FRS and GMRS. It is
important to note that one can only transmit on the FRS frequencies on these
radios unless they have a GMRS license (see below).
FRS frequencies are:
Channel No. (MHz)
1................... 462.5625 8................... 467.5625
2................... 462.5875 9................... 467.5875

7................... 462.7125 14.................. 467.7125

General Mobile Radio Service (GMRS)
The
General Mobile Radio Service is not a "No-License" service, but if you
are looking for the ability to talk farther distances, use mobile and base
radios, talk through repeaters, and use higher power, but don't want to get an
Amateur Radio license, then GMRS might be good for you. The license costs $75
for 5 years. This allows you to use radios up to 50 watts output and you can
even access repeaters to increase the range of mobile and handheld units. The
FCC only issues GMRS licenses for families. Organizations can no longer get a
GMRS license. See the FCC webpage, below, for more info.
