Here is the message I wrote to David...Everyone was asking about it.
Hi , David , sorry to hear about your trouble with the Super Dooper Turbo Tune. As for the components changed? I doubt it. As for peaking it out to look good on a meter , you got it. I can take that radio and by shorting out"1" capacitor make it swing 150 watts on your meter. Yes it is true.You
see meters like DOSY (although nothing wrong with them when used correctly) and other types just love DC voltage. They suck it up. Did you ever hook a 9 volt battery to your DOSY? The darn thing swings to 1000 watts plus. Well what happens is exactly what you said , they clip and flat
top the envelope so much that it tends to create DC out of the RF sinusoidal pattern. When this happens , small spikes form on the flat topped areas which are harmonics coupled in from the DC. This when presented to a power meter looks really good as far as false power. The TRUE way to do a peak is to maximize the carrier and still have the drive to modulate it 100% without flat-topping and clipping. |

307,
I saw on EEI's message board where one of their techs posted that the 20 watts someone's radio was doing on a PDC600 meter was supposed to be multiplied x2 to get the actual power.....Okay??? Yeah right! |

307,
I have not tuned up as many radios as you, but i submit that if one keeps the carrier as design paramators and brings up modulation to 98% the radio will get out great sound super loud and last a very long time and one can still use a stock mike and it won't sound muffled. |

that sounds exactly like what I did to my 257 Magnum......turned up the modulation on rv4, backed it off a little.....buttoned it back up.
Left the am carrier alone.
First time I used it I got the best compliment I ever heard..........
Yeah I hear him here also.......AND IT SOUND GOOD TOO....!!!!!
