Found some info here at http://www.w4zt.com/freqs/frs.html for FRS / for
FRS/GMRS (UHF frequencies)

Found some info here at http://www.w4zt.com/freqs/murs.html for MURS
(non-licensed VHF frequencies)

But here is info I had saved on my computer..

List Of FRS/GMRS Frequencies And CTCSS Tones 

Here is a list of the FRS & GMRS Channels and their Frequency assignments.  
FRS max power 5 watt, GMRS max power 5 watt on shared FRS channels, 50 watt
max on channels 15-22 shown below.  

GMRS license ($85/5 yr) required to operate on the last 7 frequencies
(15-22) which are also often used as repeater frequencies (repeaters would
be +5MHz offset, i.e. transmit on 467.xxx)

Most HT's won't run more 5 watts in simplex mode, most FRS radios are even
less. If you are running a mobile and using a shared FRS frequency, you must
reduce power to the 5 watt max output levels. Don't expect a range more than
a mile, depending upon terrain, no matter what the mfg claims you can get up
to. We don't have any tall mountain tops here to broadcast back down into
the valley. :)


Channel Use Frequency (MHz)  Channel Use Frequency (MHz) 
1 FRS/GMRS 462.5625  	12 FRS 467.6625 
2 FRS/GMRS 462.5875  	13 FRS 467.6875

4 FRS/GMRS 462.6375  	15 GMRS 462.5500 
5 FRS/GMRS 462.6625  	16 GMRS 462.5750 
6 FRS/GMRS 462.6875  	17 GMRS 462.6000 
7 FRS/GMRS 462.7125  	18 GMRS 462.6250 
8 FRS 467.5625  		19 GMRS 462.6500 
9 FRS 467.5875  		20 GMRS 462.6750 
10 FRS 467.6125 		21 GMRS 462.7000

These frequencies and tones are common to all FRS and GMRS radios in
existence. Any combination of the two can be used when communicating between
family and friends when hiking, shopping, car-to-car, or any other possible
use that you may have.

Please note that these tones, despite retailer advertising, do NOT provide
privacy to your conversation. While using these tones, you may only hear
others on the frequency using the same tone; however, anyone with an
FRS/GMRS radio (with the same tone or even without a tone at all), or even a
scanner tuned to the correct frequency, can hear your conversation clearly,
if they are within range. The CTCSS tone system was not designed for
communications privacy, so much as it was designed to keep the user from
being pestered by communications or interference he/she does not wish to
hear. It is also used in the Amateur Radio spectrum, particularly on
repeater systems that are located in areas where interference is a major
problem.

I have never heard of these frequencies in any of the stuff I have read on
Ham radio.  It surely isn't listed on the ARRL Band Plan.  I wonder why??

I will check them out.  Thanks.  Anyne know a link to learn about these
Freqs??
