Well, the older Cobra's were some pretty nice rigs...big, though...the 
148GTL is still in fairly high demand out here in Arizona, don't remember 
if Cobra (Uniden, under the Cobra brandname) made anything newer than 
that one.
 
The 148GTL-DX was the export version of this particular radio, again, 
another one that's still in high demand...prices of $200-$250 for a used 
one can still be commanded if you have one for sale (no, I don't).
 
I bought athe predecessor of the Uniden PC-12x series, which was also 
sold as a President...the AX-144, which is one of the newer 
models...can't be slid or expanded in coverage, unless you have lots of 
$$$ to waste.  As a bare-stock radio, and with a decent antenna, it will 
do a fine job; that's the rig that I have now in my truck.

For all of those who are humor impaired, Dave was referring to a mobile (you
know one of those hanging decorative thingies) made from old CB's as the 
objects hung from the strings :-)

IMHO, one of the best mobile SSB units ever made was the old Cobra 138XLR
(Uniden) and it's President and Teaberry cousins. I have (or more precisely,
my father has) the Cobra 138-XLR serial number 0000001 unit. It is hand,
soldered, has paper labels instead of silkscreening/stamping on the back panel,
and is the very unit that was sent to the FCC for type acceptance testing.
Nowadays, I don't think the FCC returns the units sent for type acceptance
testing, I think they keep them indefinitely.
How'd we end up with it you ask? Well after it passed the FCC testing, it was
returned to Cobra headquarters who promptly sent it to White's Auto, Inc.
for evaluation to see if they wanted carry the new model in their CB line since
White's was the nation's highest volume retailer of Cobra CB's at the time.
My dad was on the team that made the purchasing decisions for CB equipment
and ended up getting to keep this unit for use in his department's office,
using it as a base rig with a 12 volt power supply. After Whites went bankrupt,
all the electronics equipment, spare parts inventories, and assorted junk was
liquidated from the service department and my dad purchased it along with a     
truckload of other CB's and electronic junk at the liquidation.

What you are trying to say is that the reflected wave changes the 
operating point and causes the amplifier to *totally* reflecte the power
back to antenna. This is a good thing if you can have all the power
*eventually* sent to tha antenna, why complain?  However, please note

a)	Nobody can build a amplifier with a pure 
	imaginary output impedance;

b)	Linear circuts' operating points do NOT change with the
	amplitude of the signal (even it is a combination of whatever
	waves). This is the *definition* of linearity;

c) 	The best efficiency is obtained when the 
	load impedance is the conjugate of the output impedance of
	the amplifier. If you have a non-zero real part for your
	load impedance, the best efficiency is that you have the same
	non-zero real part and an imaginary part with opposite sign,
	which can be obtained with the help of matching network.

I do not have access to this classic book. My university library does not
have it. All the books I have say that you have a complex output impedance
and you should try by using matching network to have conjugate match to 
get the maxmum power dilevery. It is the following equation:

		R_s  =  R_l and X_s = -X_l

If you have pure imaginary output impedance, how can you match it?

	I have recently installed a mobile in my car and have found
the range shorter than what I would like.  I'm using a two foot mag
mount coiled antenna; how much increase in range should I expect by
switching to a longer antenna?  Also, the FAQ mentions that many
radios are deliberately under tuned to make sure they are within legal
limits; what's involved in tuning it to the legal maximum 4 watts of
output?  I have a GE radio.

Generally, they all are - if you wire the mike correctly. However, most
radios do not need such a mike. Generally, all you do is overmodulate
your signal, causing splatter.

I find that the Cobra 148 GTL works just ducky.  It'll run you about 200+/- a 
few bucks, but it has a built-in SWR meter and I am told it is very easy to
add gadgets like Roger Beeps and other nifty doo-dads.

Have you had the radio checked to see if it's got the proper modulation 
level?
 
My previous message mentioned a bench-test by your local CB tech...take 
it to him, and see what he says...$20 to get it adjusted is better than 
$50-$80 for a respectable amplified microphone, which might make you 
sound worse than you do now...

I haven't heard much about the RS model but you could try the Cobra
148-GTL or 146-GTL which I have heard good things about both. I've seen
the 148-GTL for around $179 and the 146-GTL for $140 or so.

It depends on how cooperative your neighbor is.   It sounds like he is
using an illegal amplifer for his signal.  Also, his antenna is
probably not installed correctly.   Ask him to stop using his
amplifier.  Ask him also to get a book on antenna installation;
he probably needs better grounding and a probably a better antenna.
Maybe his new antenna will help.

Radio Shack now sells clip-on ferrite RF supressors.  You can clip them
on to your phone and answering machine cables.  Your cables are probably
picking up the signal.   Try a couple of these things and see if they
help.  They come with complete instructions.

I doubt if there are any mobiles currently available with SSB.
However, it does give me an idea about what to do with those
dead CBs I was going to get around to fixing.  If I included
the old Pace Sidetalk 1000M then it _would_ have SSB.  

A mobile made from old CBs would be pretty big.  Are you sure

 I prefer the Uniden PC122, Pro 640e and the Grant. All these are 
 Uniden modiles that seem to work well from what I have seen and
