Not sure if I understand this correctly but it is possible to overmodulate the positive part of the wave w/o distortion and get a louder signal? I know a lot of public stations overmodulate their AM stations up to 125% positive. So I am wondering how I can impliment this in my altready built and running transmitter. Anyone got some good ideas or schematics to make this workable? Or maybe I need special processing equipment? Is it worth it?
It is in our radio law that 150% upward modulation is permissible and I know of ham experiments to 400%.
I am not sure of the method analog, but all Google shows for DIY is digital-step modulation, etc. Wasn't interested at the time, so no bookmark
Peace!
Okay but isn't that amount of positive modulation cause distortion that is notable in music and such? I really don't know. I was thinking of building the negative clamp diode circuit for the negative modulation on my AM transmitter, but don't know if it is worth it or what. It sounds easy to do with a class E transmitter as the modulation is phased and you can cancel out the product at one specific part of the RF amp, but for a regular class C type setup it seems much more complex because you have to deal with the whole thing rather then just part of the wave? I probably drank too much beer lol. I hope this makes sence.
