Acording to my Motorola service monitor my solid state exciter cannot reach 
100% modulation.  At best I can only get 85% on the loudest peak and the 
average runs around 65-70%.  I am told I sound very good on am though.  When 
I was running a
titan amp and watching the peak reading led display it took 500 watts of 
carrier with the loudest modulation peaks to reach 1500 watts.  I damaged 
stereo equipment in the house running too much power so I sold the Titan to 
pay for the damage and bought a Clipperton because it should not be capable 
of that much power but 25 watts on am from the solid state exciter is not 
enough power to be heard under most conditions.  I find that lowering the 
power on the exciter to around 12 watts gives a higher average of modulation 
since the alc does not get involved at all.  MY main question was how much 
carrier can the 4 572B's run and have enough headroom left for moducation 
peaks?
