 Wayne you and many of us will remember the PLL 02A which will do just
 this with out to much caoxing, in fact if my memory serves me correctly
 eith CQ or 73 had several articles on the 10 meter conversions in 
     ^er  the late '70s or early 80's.   Hmm wayne a verac and instant
 FM.

 Well I must disagree with one. The FCC did come down on Uniden sometime
 ago on their HR2510 and Uniden did do the PLL chip change to stop the
 26-30mhz conversions and other manufactors in the USA have followed.
 But remember not all manufactors have to meet FCC approval as they
 are not sold in the USA. Look at the Galaxy range of equipment for
 instance. For that matter even the TS440's and the likes.
 
 Ah well who cares, may be most of them will gett their tickets
 and run a few kw's on 470 doing a moon bounce or two or fire
 up the old #19 Set on 80 meters (75m for you chaps) and realise
 this is just a better class of cb operator (big grins)

The 2600 has a PLL that is rather fussy about where it cares to mix
frequencies, and as you say, will not go willingly.  A PLL chip is available to
replace the existing one, which then will allow out-of-band operation.  This
chip goes for (the outrageous price of) $65.  It is CMOS, and the old one is
NOT in a socket, so have a blast soldering it in.  Definitely NOT worth it.  As
to increasing output power, why spend $70 or so modifying it for more power
when you can BUY a good quality 10m amp for the same price?  I think this
person is either looking to get us all buzzing on the net, or he's just plain
stupid.  (the person in the original post, that is)  Comments?

A picture would be worth a thousand words here.  This is very old AM
technology, so some may not be familiar with the technique.

We don't need linearity to create a sine wave of constant amplitude
(like FM).  This technique uses Class C (or D) and relies on high-Q tank
circuits to shape the sine wave.

Now, imagine a voice transformer with the secondary side connected
between the plate(collector) and B+(+Vcc).  When you impress a voice
signal on the primary side, it effectively increases and reduces
B+(+Vcc).  This modulates the carrier and AM is the result.

Like I said, this is very old-tech.  With the advent of class AB1 solid
state equipment, its application is rare.

Unfortunately speech compression is not really supported by too many

This is a bit disappointing really since I had to build a seperate unit 
myself to incorporate compression with a proper voice passband and ever

The Catalog Number for that antenna is 21-940.  You will also need the 
278-208 adapter if you use a Walkie-Talkie. The antenna costs $26.95
and the adapter if needed is $1.79.

Anither point to remember is that you can overcompress a waveform. After

Speech compressors are just as prone to abuse as straight amplifiers.

It depends on how the modulation is applied. If you are attempting to
amplify an already modulated signal - such as a SSB signal - then your
statement is correct.  If you are amplifying just the carrier, which
will be plate modulated, then a Class C amp is fine. 

A more proper statement is that a Class C amplifier will not properly
amplify an INPUT SSB or AM signal.

 Jason,
  An SWR meter measures the Standing Wave Ratio hence SWR. What SWR is is the
amount of reflexed power recieved by your rig from a mistuned antenna. A 
properly tunned antenna will have a SWR between 1.1-1.5 over all 40 channels.
As far as price goes, visit your local Radio Shack. Their swr meter costs $20.
Follow the instructions as far as the use of the meter ad tuning of your 
antenna. As far as leaving the antenna untuned, performace can fall through the
floor. If you use a badly tuned antenna for long periods of time, you could
blow the finials out of your rig. Your safest bet is to buy or borrow a meter

The meters measure the ratio of the power that goes into the antenna
to be radiated and the power that is reflected by the antenna.

You can buy a meter at Rat Shack for $20 or $30.

For short lengths of coax, like in your mobile, high SWR will not cause
any noticeable loss in performance - with the caveat that the transmitter
will not be harmed by the high SWR and will not reduce its output power
due to the SWR.

It is always best to tune the antenna. However, regardless of the
instructions - thousands of people have used them without doing so.

PLL stands for Phase Locked Loop. It is part of the frequency control

Compressors are prone to abuse, but usually by those who'd abuse a 
straight amplifier stage anyway...
 
It's a bit tougher to get a compressor to REALLY sound crappy; many of 
them are pretty much fixed as to the amount of compression you can get on 
them (I'm refering to those with the compression circuitry in the radio, 
not in the microphone...those with a knob on a mic will almost always 
have 'em maxed out...then all you can hope for is for the battery to wear 
out...  :I  )
