Hi Mike:

A couple things to be aware of...GMRS requires that you obtain a license from the FCC. It cost around $80.00, and is good for five years. GMRS allows up to five watts on a hand-held, and I think it's 45 watts on a mobile, base, and/or repeater. You also allowed to use larger hi-gain antennas, external mobile antennas, and base antennas on your roof, or a tower. It is strictly limited for family/personal use only, on any newly issued license. There are a few businesses that were grandfathered in under the new law, because they had been using it for business prior to the changes in the license restrictions. So this means you can not use GMRS for things like a landscape service, security company, etc. All members of a family can share one license, but other than that, each user is required to obtain their own license. So if you, and your buddy that lives across the street want to talk on GMRS, you would both be required to obtain your own license.

FRS does not require a license, and can basically be used by anyone, for any legal purpose. You are limited to 1/2 watt however, and operating within the FRS channels only, none of the GMRS channels. You are not allowed to change/modify the antennas that come with FRS radios, so you are restricted to using the supplied short rubber duck antenna.

Typical range for FRS is 1-2 miles. GMRS is 1-5 miles, without a repeater. Depending on the repeater, and the height, and location of the antenna, range be more like 20 miles, or more under certain circumstances.

Hope that helps.

The fcc for one reason or another no longer allocates the "675" pair as the national distress/ travelers assistance ch. Just found this out, from the personal radio steering group.{prsg.org.}

For some odd reason the ".675" pair is no longer designated as the distress or travelers
assistance ch. Just found this out myself. {prsg.org.} is the source.

Sorry for the dupl. d-uh!

Hi Macomb and all,

Just to clarify your post a bit, FRS/GMRS used to be part of Class A CB before that segment of UHF was reallocated to public service with the retention of what could be loosely termed "family radio". Like Class D CB (11M) it was originally assigned to business and personal use so old business licenses were grandfathered and new applications assigned to the BRS now called "land mobile".

"GMRS allows up to five watts on a hand-held, and I think it's 45 watts on a mobile, base, and/or repeater."
The 5W limit is technical, not legal. A hand held is limited due to heat dissipation and battery capacity, a mobile rig and suitable power source can easily be used as portable.

"Typical range for FRS is 1-2 miles."
I'd like to see more than a few blocks over flat terrain in a suburban environment.

"GMRS is 1-5 miles, without a repeater."
I get a bit more base to mobile on the 70cM ham band so like they say, "Your milage may vary."

"Depending on the repeater, and the height, and location of the antenna, range be more like 20 miles, or more under certain circumstances."
A repeater in an ideal location can give considerably more, less than ideal considerably less. Then there are obstructions to consider, I can't get one on a mountain 20 miles to the north while over flat land to a 200' tower I get 60 miles to the south.

I hope that helped your help. (;->)

Well, not quite. See 95.29 and 95.135 of the rules.

There are 5-watt ERP limits in certain circumstances. One is that GMRS licensees can use up to 5 watts ERP on the 462 halves of the FRS pairs. This DOES NOT apply to FRS users. FRS users must use FCC certified FRS radios ONLY and at the power limit for FRS - 1/2 watt ERP. Note that these are Effective Radiated Power (ERP) values, not transmitter output values.

Another low-power limitation relates to GMRS "small base stations" and some GMRS station types along the eastern Canada-US border.

GMRS mobiles can go up to 50 watts transmitter output power (the absolute maximum for GMRS stations if not limited in another rule section).

Remember to use only equipment which is FCC certificated for GMRS on GMRS and only FCC certified FRS radios on FRS! The exception is GMRS licensees using GMRS equipment on the FRS frequencies as mentioned in 95.29.

Here's a link to the rules:
http://ecfr.gpoaccess.gov/cgi/t/text/text-idx?c=ecfr&tpl=/index.tpl

select "Title 47" and GO, then click on Parts 80-199 under volume 5, then click on Part 95.

Hi Macomb and all,

So GMRS Frequecies are not allowed to be used for anything but personal use? They used to be able to be used by businesses too.

"There are a few businesses that were grandfathered in under the new law, because they had been using it for business prior to the changes in the license restrictions."

You can not obtain a new GMRS license for any type of business use. FRS however can be used for business.

Also, not quite.

"§ 95.101 What the license authorizes.

(a) A GMRS license authorizes a GMRS station to transmit messages to other GMRS stations at any geographical location within or over the territorial limits of any area where radio services are regulated by the FCC. These points are listed in Appendix A. "

and

"§ 95.181 Permissible communications.

(a) A station operator for an individual who is licensed in the GMRS (other than an employee of that individual) may communicate two-way voice messages concerning the licensee's personal or business activities (see §95.179)."

Currently, you can't be a business and get a new license but licensees can certainly use their existing licenses (whether individual or non-individual) for business use. If you are an individual licensee and wish to use GMRS in your business, then each employee you talk to must have a license.

"§ 95.183 Prohibited communications" does not prohibit business use for any type of licensee. There are some specific prohibitions like "messages for hire" but there is no "personal use only" requirement. If you want personal-only, you should get a license under the amateur radio service.

Non-individual licensees are, however, restricted to business-only use. They cannot use GMRS for personal use. See 95.179(b)(2).


The rules changes toward the current individuals-only licensee structure were primarily changes to the LICENSE ELIGIBILITY, not to the STATION USE.

"There are a few businesses that were grandfathered in under the new law, because they had been using it for business prior to the changes in the license restrictions."

You can not obtain a new GMRS license for any type of business use. FRS however can be used for business.
