Default Why is my 2watt radio only 0.83watt? advertised output doesn't match certification specs.

Engineering submitted the specs and the Marketing Dept developed the
packaging...... Somehow, the Marketing folks seem to sleep well at
night, anyway!

I got a 22 channel walkie talkie thingie from Wal-Mart, which you
guys refer to as GMRS/FRS hybrid radio.

The manual says 0.5 or 2W(selectable) from GMRS/FRS shared channel 1 to
7, 0.5W on 8-14 as a FRS radio and 15-22 GMRS only selectable between 0.5
and 2W.

The package reads "2watt up to 5 miles"

I got a copy of FCC certification sumbission for this radio and it reads:

478mW FRS
831mW GMRS


How did the 831mW on certification submission turn into 2,000mW on
manual and package?

JerC-

They lied!

My guess is that if challenged in court, they might claim that the higher power
was either

a) The result of using the car battery to power the radio instead of its
internal batteries,

or

b) The total power delivered by the batteries.

The case for (a) is based on power output being greatly affected by DC voltage.
A slight increase in voltage sometimes results in a higher percentage increase
in output power.

The case for (b) is based on FCC limits, which would likely be exceeded by (a).

I doubt that Walmart cares, but you could use this information to justify a
refund after their normal return period has expired.

The manufacturer might be using the old audio-amplifier trick of
listing the total power consumed by the radio (output +
losses/overhead) on the packaging, maybe? If they didn't say "2,000
mW RF power out" then they might not be actually lying... just coming
to within a split red fiber-optic of doing so.
