Glad to do it and I have to admit my radio was off freq just a tad but I can blame it on my sons ear as he tuned the reciever and controlled the recording on and off.Wow that was intresting. I guess you need to choose your words when using a C box with a cap on the relay...
Thanks for taking the time to do the test mack.
Hey Mack, same radio different amplifiers. The test may have been a cheat. Notice that the "AB1" amp was narrated as sideband. Were all the tests on sideband? Clearly "C" is not for side band by nature. We need a new test, same equipment. Comparison fixed on AM, comparison fixed on SSB. Then we will know. The difference in the test produced very clear audio on SSb with an AB1 amp, and lesser quality on the other amp, but conditions unknown. If we take the test as SSB all equal, then the AB1 had superior modulation, hello, modulation!
Class "C" amps are not suited for AM, let alone SSB. They are not linear enough to properly amplify the signal. They are intended for FM and CW.

Thaaaaat's It!!!A class C amplifier can work on AM or SSB if it's operated in the linear portion of it's amplification curve. That doesn't mean it will work -well-, just that it will work. Why is a class C amplifier touted as the 'end all' for AM amplifiers? Cuz you can see more power output than for other classes of amplifiers. You don't have to know just a tad bit more to figure the biasing needed for proper operation. And because they've been around dang near forever so have become a sort of 'standard' for CB amplifiers. If it's 'older' it's gotta be better, right? Yeah, right. You've got your choice, big watts or good quality signal. You decide, then live with it.
