I thought 100% was ... well, all... everything. How can you have 101%, or more? I belive that falls right in with these people that have told me they can mod a D&A Phantom to do 1500 plus w/ 6lq6 tubes. OK, well I guess your just getting about 300% out of them then right? But in therory, you can never get 100% of anything dealing with electronics or electricity. I supose that is due to "heat".. or "loss" So im going to call BS on about 500% of the BS I here.
Well I'm new to this cb game, and I'm sure 10 people are gonna jump in and tell me I am wrong, but here goes.
when you modulate a sign wave at 100% pos, and 100% or less in the neg. direction, with out flat topping the sign wave, you are only getting APROX. 45 to 55 % audio density.
This density is what is perceived as loudness to the human ear.
You can keep turning up the gain and over modulate, which flat tops the sign wave and pinches the carrier, your watt meter will really read very high numbers and have lots of swing and you WILL have that tight, pinched sound, if you are even able to be heard, I think you have thease people before, they sound like they are screaming into the radio.
From what I understand at this point in my small understanding of electronics is that if your equipment CAN produce more than 100% in the pos. direction
WITHOUT exceeding 100% in the neg. direction and without flat topping the sign wave or pinching the carrier, you have achieved asymmetrical modulation, and in exact terms asymmetrical modulation would be considered distortion, as any sign wave that is
not symmetrical is distortion.
Ok now for the weird part of the way it works, asymmetrical modulation ( a form of distortion ) will allow for more " head room ", IE 80 to 90 % audio density. IE your radio will be louder.
As far as the 1500 watts out of a 12 tube d&a Phantom, hell any 5th grader can make one do 1500 no problem, it will last about 5 seconds, you will get NO audio, and you will have to supply apx 277 VAC into the primary side of the transformers.
No sweat, actually this is not true, but I think you get the drift of what I'm saying.
I personally don't believe anything I hear and only half of what I see.
If you truely interested please email me and I will try to explain more
Also their is a guy on here 302 that CLEARLY shows 300% + modulation, check it out
This guy also
