You partly right but this is well what I said in my post. The problem I
speak about is completely different.
As usual your comments are out of subject and from what I read you don't
even know the problem trying to compare wmy request to "CB". ! It is a pity
that an ham has a so bad ham spirit....


The real pity is in the fact that a ham has such a ****-poor
understanding of how SSB modulation works. Furthermore, if you want to
talk "out of subject", perhaps you might want to check your own messages
on rec.radio.* forums. Also, if you choose to interpret replies to your
messages that don't kiss your ass as "bad ham spirit", that's your
prerogative. Now back to the topic:

The reason I don' have 100W on SSB is due to the audio limiter so by
bypassing it I can get 100 w whatever your (false) opinion in that matter.
This is nothing to do with the compressor...


This is a complete bull****. How do you know you don't have 100W on SSB?
Have you used an accurate laboratory standard peak-reading wattmeter? Do
you understand the nature of the SSB voice modulation? It is unrealistic
to expect that your general purpose amateur radio wattmeter will
indicate 100W during a normal SSB transmission. Just a reminder: an SSB
voice transmission transmits a modulated signal that has a dynamic
response of 20-30 dB, which means that the peak power of plosives will
be fairly close to 100W while fricatives, nasals and vowels will produce
anywhere from 0.1W to 100W, depending on your speech (which, in turn,
depends on the language, sex, physiognomy and many other individual
factors).
You want us to believe that although Kenwood provides a technical
specification for its transceivers (TS-570 included) that claims 100W
output on all amateur bands and in CW, SSB, FM and FSK modes, they fail
to deliver on this specification because they employ an "audio limiter",
so the way to get full power out of the rig is to bypass this circuit???

An accessory plug can bypass audio and therefore left the mic connector
unchanged so I can either use the TS570D in the standard way or connect a
mic to the accessory plug and operate full power SSB.


In other words, you can use an accessory DIN connector in the back to
input audio instead of going through the mike plug. The problem is that
this input goes to the same spot as the mike audio input. But, wait,
here's a magic solution:

The mod is relatively simple and requires a jumber and the removal of 3 or 4
smt components.
Of course this is not thanks to you that I had this information that may
interest others hams. Others did hopefully.


And here we go, just what I was talking about when I said you were
wasting time on CB-like schemes - that band is full of "experts" who
"increase" their power by employing all kinds of charlatan mumbo-jumbo
techniques, from audio boosters to magical 30 dB gain antennas. The
results are obvious for anyone who ever bothered to listen to that ****
when they illegally encroach on our 10 meter band.

Now you come along and make an ass of yourself first by completely
misunderstanding how SSB power is measured, then by modifying a properly
functioning rig with what can only be interpreted as a mod to eliminate
the ALC circuitry. The result will be your signal splattered all over
the bands and an increase in TVI.
Last, but not least, even if what I said was completely untrue, even if
you were able to magically "increase" your SSB power from, say 70W to
100W, this increase in power would result in the astoundingly lame 1.5
dB!!! And this at the expense of splattering the bands?

I told you once and I'll tell you again: build a better antenna instead
of wasting time on CB-like schemes.
