It would be illegal, as you say - it would no longer be type accepted.

You are not allowed 5 watts output. You are allowed 5 watts input to
the final amplifier. Because of circuit inefficiencies, the best you
can get out is about 4 watts. It usually runs 3-3.5 watts.

I am not sure what you mean by wanting to use it with a protable phone.
You will have to explain further.

Hmmm...I don't know why this never struck me before, but the above explanation
of an AM signal is incorrect.  The transmitted signal does consist of a
carrier plus sidebands above and below; however, the amplitude of the signal
component at the carrier frequency is *constant*.  This seems to be
counter-intuitive to most folks, but the 'scope trace everyone thinks of
as "AM" - a carrier-frequency signal whose amplitude is wiggling up and
down - includes ALL of these components, carrier and sidebands, at once.

In other words, the component at the carrier frequency carriers NO information;
it's all in the sidebands.  You could eliminate the carrier completely and
still recover the transmitted voice (or whatever); if you eliminate the
sidebands, though, there's nothing left - just carrier.  (Simply eliminating
the sideband is exactly equivalent to double-sideband suppressed-carrier
modulation, or DSBSC.  This is the first step in one way of making SSBSC,
single-sideband suppressed-carrier, which is what is almost always meant
by "SSB.")

The sidebands aren't a "side effect" of amplitude modulation, they're the
most important result of it!

To best understand AM and SSB, you really have to bite the bullet and
go through the math; grab a book of trig. formulas, and you can easily
find out what happens when you multiply one sine wave by another - you get
DSBSC.  If you add a DC offset to either of the signals before you multiply
them, you get normal AM (and you will understand how the most common AM
modulator works).  SSB cannot be directly generated through the simple
multiplication of two signals; you either need to filter a DSBSC signal
(the most common approach) or do some phase-shift and re-mixing tricks.

       After serious consideration and budgeting, I've decided to
install a set of 17 x 9.5 wheels on my '87 Trans Am.  Now, after
deciding, I need to know exactly how to do this.  I know it can be done
because I've seen them on late model Camaros in a few magazines.  I
figure that the rear wheels shouldn't be a problem.  The front wheels,
however, are where the problem will be.  One magazine gave a vague
description of a Camaro saying something about a ten millimeter offset. 
I've also heard stuff about removing half a coil from the front springs
and removing the fender flares.  If anyone out there has done this to
their Firebird or Camaro, please tell me how its done.  For all I know,
there might even be a conversion kit out there right under my my nose
(Herb Adams or something).  Any input would be well appreciated. Thanks

Because NHRA is only concerned with raw acceleration; and they cannot afford

As for NASCAR, well, it's real popular in the South.

I am probably making a mistake by responding, but I haven't been flamed in
a while . . .

The Fiero is NOT a take-off on the X1/9.  The X1/9 was introduced LONG
before the Fiero and was not a big seller when the Fiero was conceived or
sold.  The Fiero was sold to GM execs as a cute commuter car and was
designed outside the typical GM design scheme at the time.  Compared to
other GM projects, it was produced at a very low cost, primarily by sticking
to using parts from the corporate parts bin.  When the car was designed,
there was no market for sports cars and GM would not approve the product
if that were the niche that designers went for.  The problem occurred when
they hit the market and people thought they were sports cars.  After the
introduction of the Fiero, the sports car market started to open back up.
The designers went back to work to try to make the car match its sporty looks
and did reasonably well, but there is only so much one can do with Chevette
and Citation front suspensions.  The 88 GTs are definitely the best of the
bunch.

I think the 86+ Fiero GTs (sans spoiler) are the much better looking that
the X1/9.  I got around 32 mph (highway) with the 2.8L V6.  There is much
more storage space in a Fiero and it is easier to work on a Fiero.  (An
old officemate had an X1/9 and we would compare cars.)  I also trust
GM electric over Italian electrics.

There is more room to improve a Fiero.  The "mill-and-drill" procedure (where
the body panels mounting points are all drilled at once, so the body panels
are all aligned) makes the Fiero the ultimate kit car.  You can buy kits to
make Fieros look like most anything in the Fiero's general shape.  A number
of sources offer suspension kits for giving the car better handling.  The 
engine bay can accomodate larger motors.

Of course, as much as I liked my Fiero, I gladly gave it up for my Lotuses.

You shouldn't have lost your brakes, just stand on them harder.  I'm
surprised that it stalled at all.  GM and Chrysler (and probably Ford,
but I've never tested it) automatics have a ratchet device that prevents
damage to the tranny.  You will stop quickly, but I've never had an

I worked with a kid recently who has a Mustang GT convertible with the 
Viper alarm and that perimeter sensor that you mentioned.  That has to
be the MOST annoying alarm in production!!  If the branches on the tree
next to his parking spot moved in the wind, it barked "STAND BACK--PRO-   
TECTED BY VIPER!!".  It also went off if you parked next to him and got
out of your car on that side.

Several people told him to leave it turned off at work or he was liable
to come back to find his door kicked in.  The problem went away when he
got fired and we figured it was kind of an extension of his personality
anyway but they both were extremely annoying.

I realize that our urban society and the previlent theft rate encourages
the use of these things, but they certainly can be a pain in the *** 
for the people who have to deal with them.

I was in a honda dealership this weekend and they said that Civic coupes  
would be out in about a month or two.  They have a picture in their 93  
literature, it does look very good (i don't even really like the sedan)
So my guess would be the coupe...the sales geek claimed it wouldn't cost  
any more than the sedan (i hope not, i saw a civic sedan on the lot with a

I just (last week) put a set of Yokohama AVS A+4 onto my Saab 9000 turbo,
and have put 1000 miles on them already, in a mix of rain (TS Danielle) and
shine.  I really like them - the car feels more solid than it did with the
NCD 2s, and I think the ride is smoother. The Yokos seem to soak up expansion
joint bump-thump better. They certainly have much stiffer sidewalls -
it took two mechanics to lever them onto the rims.

This may not be directly applicable to you, since you're looking at the
U+4 which are mostly HR rated (the A+4 being VR), but you might find it
encouraging. One potential downside may be in finding a dealer - the closest
one to me (NJ Shore) was in Staten Island. But since I got mine mail-order
(Meier Bros in Illinois, whom I can recommend), that didn't bother me.

I've heard it many times - wife wants a car to haul the kids
and husband wants a pickemup to haul/fish/hunt/cruise/tow the
race car, etc.  I've found the answer!

From the front seat forward, this '92 Chev CrewCab is exactly
the same thing as the '92 Suburban I reviewed about a month ago.
But from there back, this thing is loooooonnnnnnnggggg!  But the
length (don't have the wheelbase #'s in front of me) is justified
in that it has a roomy full size rear bench seat (reminds me of
the old Buick Dynaflow in size), 4 doors and an 8-foot bed.

When driving around town, you've got to keep in mind the extra length
and wheelbase in mind, to avoid catching the curb on a tight right
turn and realizing that this rig doesn't quite fit in your typical
parking space.  Other than that, it's no different to drive than the
Suburban.

The only (again, like the Sub) downside is that this beast has a 454cube
motor.  Great for towing, but gas mileage........forget it.  By the way,
this one was a 4x4.
