OK.   I'll quote the CB reg here.  This may clear it up....
 
 95.411  ( CB rule 11 )
 
     par. c   "The FCC will presume you have used a linear or other 
external RF amplifier if--"
 
 (1) It is in your possession or on your premises (there it is, BUT...)
      AND
 (2) There is other evidence that you have operated your CB station with 
more power than allowed by CB rule 10.  ( 4 watts AM Carrier power, 12 
Watts PEP SSB)
 
   Sooo.... in my interpretation, posession IS illegal IF say, other 
evidence, such as MASSIVE bleedover and such exists that the FCC thinks 
someone is using that linear on CB.
 
 
Regs continue...
 
  (d)   Paragraph c of this section does not apply if you hold a license 
in another radio servive which allows you to operate an external RF power 
amplifier.
 
    In that case then, possession is NOT illegal, but only so paragraph 
(c) states.   CB rule 10 STILL is in effect....
 
   Which brings to mind something I heard...... A guy figures when he gets 
his ham license, it is OK to use his linear.... WRONG!   As 95.410 (Rule 
10) states "Your CB station transmitter power output must not exceed the 
following values under ANY circumstances:
 
  AM (A3) 4 watts (Carrier power)
 SSB      12 watts Peek Enveope Power
 
 
 
   Hope that clarifies things.

A celluar-look-alike antenna is not going to perform well on CB.
I would try a AM/FM/CB combo antenna, such as the one sold
at Radio Shack.   I have had good success with it.  It's not as
good as the ol' 8-foot whip, but it will work a heck of a lot
better than what you have now, and it does not look like a
CB antenna.

well, new cb's still come with a copy of 'cb rules' that spell out the 
basics in simple language (giving the part 95 paragraph numbers for 
reference), but and actual copy of part 95 itself is something that i 
haven't seen in a long time.  a couple of years ago i wanted to check 
something in part 95 and went into my local rat shaft, figuring that 
since they sell cb radios that they'd have a copy lying around i could 
look at.  no soap, when i asked if i could look at a copy of part 95,
the guy behind the counter said 'sure' and handed me that silly little 
'cb rules' thingy.  i ended up having to find it in the library.

      Sure those with milli watt have to wait till it is
  just right . I agree kilowatt will be over kill.
  but from my experence a bit more power will raise
  the  signal above noise.

It seems odd that you know how to slap together a good linear in a weekend

     Bleedover didn't seem to be a problem with it, and they reported a

I have done contacts on 19 but with a mobile antenna on my
walkie-talkie, while talking to some people on the same highway driving
the opposite direction. We talked for at least 3 minutes but even that
situation is rare. I can sometimes get out to 6 miles with the
telescopic (which I wasted an extra $20 from Maxon) on other channels at
night. I'm wondering if the Cobra HT will use RS's speaker mic since it
has a mic jack and earphone jack close to each other like one of RS's
walkie talkies. The Wal-Mart price was $88.95 plus tax.

Is the antenna specifically used for CB? I haven't seen a CB antenna

a magnet mount from RAdio Shack. I bought it from a friend for $10. The
performance is pretty bad mainly due to the fact that it is only 1 foot
and 4 inches tall. Cellular antennas work through glass very easily, but
you have to remember that cellular phones operate at 800 MHz and CB's
are at 27 MHz. Mounting an antenna on glass with a separation in the
coax looks like a big way to lose performance.

It has been illegal to *possess*, use, or sell a non-type accepted
amplifier capable of operation below 144 MHz since April 28, 1978.
There are two exceptions to this rule. 1) Equipment manufactured
before the cutoff date is exempt. 2) Licensed radio amateurs may
build or modify one external power amplifier for use in this
frequency range without type acceptance in any calendar year.
This is spelled out in Part 95.509 of the Citizen's Radio Service
rules and in Part 97.76 and 97.77 of the Amateur Service rules.
Type accepted equipment operating in this frequency range, must
be *permanently damaged* by attempts to operate in the Citizen's
Band in order to qualify for type acceptance, from 97.77.

     Actually it is 250 Km or about 150 miles that is the legal cutoff 
distance.

     Discussion of the illegal sutff (in ym opinion) is meant to 
discourage people from using such items and to try to tell them how

It is? Then why have hams modified them for use on the 10M band?

Why, when the FCC was enforcing 11M regs better, did they not confiscate
linears that were not connected to the transceiver and antenna?

I think you will find that it is illegal to sell them to the general public
but that simple possession is not illegal.

In practical terms it is, Bill. An amplifier for AM has to be cleaner
than one for SSB to produce the same amount of spurious products. And
the duty cycle requirements are much more severe for an amplifier for
AM than for SSB, about 8 times more average power is required for the
same amount of communications improvement. Since most designers tend
to skimp on power supply stiffness and cooling systems, running AM
through an amplifier creates quite a bit more stress and non-linearity
than running SSB through the same amplifier. Of course it's *possible*
to build a good clean amplifier for AM, we do it in TV broadcast, but it
isn't easy or cheap to get good linearity. Non-linearity 40 db down is 
plenty for an SSB amplifier, but an AM amplifer really needs 60 db down
and those last dbs are the hardest to get.

        HAMS may legally own and operate linear amplifiers....on ham

        As far as *I* know, cb people get hold of *10m* linears and convert
them to *11m*.....not the other way around.....
        I know of one company that sells an all band linear and in order to
get the code (I think it's in the form of an IC...)to make it operable on
10 meters, you must submit a copy of your current and valid amateur radio
license......
