Sorry if this isn't the right group to ask this, if not and
someone know of a more appropriate group I'd appreciate a
pointer.

I currently have GMRS radios that are rated at "16 miles"
(yeah, maybe on the salt flats or over water, ok, we all
know about that). The are rated at 2W on the GMRS freq's
and .5w on FRS.

Why are the new "25 mile" units still rated at 2W? What's
the difference in the two radios to justify the increased
distance claims?

Can't be frequency or a change to the privacy codes or they
wouldn't work with older radios.

Increased sensitivity/filtering? Hype?

Hype and poor/deceptive advertising. Probably the advertising dept. is
clueless
as to actual specs.

2W on a unity gain antenna should have a maximum range of 1.4km (or 0.878
miles)
given the standard receive sensitivity of 0.2u.

GMRS is CB, and therefore, your better group by topic would have been
"rec.rado.cb." However, I agree with other responses that you would
probably
get a better quality response here.


GMRS is NOT CB. See URL:

WRONG! GMRS is CB. It's defined in part 95, subpart A. All of part 95 is CB.
What you're thinking of is only the 27MHz allocation - part 95, subpart D. FRS
and MURS are also in part 95, and if you read the FCC's page on each, the FCC
indicates that each is part of CB, but neither operates on 27MHz.

GMRS frequencies are UHF- FM and requires a license and a fee for
application (~ $75 ?). Use is sharply defined. Repeater operation is
permitted. There are severe penalties for non-licensed users.

It's still CB and you know it.

"Citizens' Band radio (CB) is, in most countries, a system of
short-distance, simplex[1] radio communications between individuals on a
selection of 40 channels within the 27 MHz (11 meter) band. The CB radio
service should not be confused with FRS, GMRS, MURS, or amateur ("ham")
radio. "

Part 95 of the FCC Rules does not state that CB = GMRS
Should I believe Wikipedia, the FCC, or you?

The problem with Wiki is anyone can modify / create it.

sarcasm Give me a minute and I'll go change the Wiki to say that 490
-510 mhz is open game for anyone. /sarcasm

There are several radio services covered under 47 C.F.R Part 95. The
FCC describes three of them as being part of the Citizen Band Radio
Services (CB, FRS and MURS.) The GMRS radio service is not described
by the FCC as being part of Citizen Band Radio Services.

I shall agree - not CURRENTLY is it called a CB service. GMRS is historically
"Class A CB." What is normally called "CB" today is historically "Class D CB."
