Hi,
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 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...

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.

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.

Speaking normally (without shouting) in their mike with normal

50-60 watts (of course in CW they reach 100 W)
But some arrive to move the niddle to about 100 watts in SSB using their
barefoot RTX...

This is nonsense, Thierry. If you shout loud enough into the microphone,
of course you'll notice a higher power reading on the wattmeter, but
so what? SSB transceiver should be adjusted so that the reading on the
ALC scale stays within limits. Anything else is overmodulating and
causing splatter.

It seems that some RTX can reach the nominal power doing a hardware
modification at the mike itself to increase the 60 w displayed in SSB to
about 100W. According these hams there is no disadvantage to make this
change.

If such a modification exists for that TS570D or for any mic, can a ham
do
it himself or can he ask his dealer to make the modificationcan

There is an audio booster circuit, which is actually a dynamic
compressor and it works by increasing the level of the softer portions
of your speech while keeping the louder portion the same (hence dynamic
compression). If properly adjusted, it may give you some signal boost.
The drawback is that the other side will be able to hear a mosquito fart
in your shack if the signal is good.

Then there's a high audio booster, which increases the higher frequency
portion of your speech, but this is generally included in modern rigs.

If your mike can drive your Kenwood's ALC to the limit when speaking
normally, there is nothing wrong with it. Build a better antenna instead
of wasting time on CB-like schemes.
