DO NOT CLIP THE LIMITER!!!! There are several reasons why not to clip the limiter.
1# ALL audio will be uncontrolable AM SSB FM deviation
2# The gain you see in increased audio power will bring ALOT of harmonics because the signal is flat topping and clipping, there are better ways to modify the AM amp chain and retain the ability to limit the gain.
3#In most cases you will lose avg power out. You have to have REAL test equipment to see this not a Dosy meter and your friends ear.
I have only seen a few A VERY FEW radios that when the limiter was removed the radio did not show any distortion. The reason being is because those radios had such an anemic Audio amp, it wasnt capable of driving the amplitude to %100.
And just for your information, anything over %100 IS A FALSE /unrealistic number.

Some more technical information:
The reason most meters (i.e. dosy, workman etc..) read a higher power output after the limiter has been disabled is because the meter is unable to diferentiate between the target freq. of 27 Mhz and the 2nd and 3rd harmonics of 54 and 81 Mhz.
What happens is, those harmonics leave the radio and travel down the coax to the antenna, the main or "target" frequency leaves the antenna because that is where the antenna is resonate and has the lowest resistance. however the 54 and 81 MHz signals are stopped at the antenna and try returning back to your radio since the antenna has no or little resonance at those frequencies. Well when those signals get back to you dosy watt meter, the zener diode that drives your meter movement doesnt see them as SWR(because its tuned/designed to only check the swr at 27MHz. So those harmonics are read as forward current by the zener diode and therefore shows as more forward power, when in fact if you view this on a spectrum analyzer, you will notice the power has dropped on 27MHz and risen on the Harmonics.
Alot of people dont understand this, and there is ALOT more to it then what I have just explained. But this is about the most simple explanation I can give.
