what makes or gives the amp their efficiency and how do you do figure out the efficiency. For example Ameritron says 65% efficiency how did they determine that as well, just curious, again I know I ask some reall weird and sometimes stupid questions but who is going to ask them LOL and how many...
What happens if one changes the roller inductor from 24-uH to say 35-uH or 44-uH or even 77-uH? Or change out air capacitors to vacuum one instead of 500pf 10-1200pf?
Curious about it for something kinda doodling in my head for a home made tuner.
what is the ?-???? pf range of the air capacitor? ( is both transmitter and antenna air coils same capacitance? )
what is the ?? uH range of the inductor and wire gauge size(16ga, 14ga, 12ga 10ga)?
I've tinkered around 14-10 awg seems work well. Larger 8-6 tried came to conclusion was waiste of money 14-10 awg worked fine and very pleased. Just article looked to good to be true aka a lot of BS seemed to be.
justvran across this for modification of imax 2000 and also these other antennas for CB as well as Amateur bands hmmm.

Any input? Anyone ever used this or had imax 2000 ect modified?
Wow excellent explanation.
Mine doesn't have a scale just a line and compression numbers 10 ----- 20 ect suppose to keep it on compression between 10-20 no one has said I am over modulating and I use either a stock mic or a D-104 and run it v v v low on gain setting on bottom of it.
We're do I start LOL, everything I bought is from asking, reading and all here.

What I did would it benift me or 60/40 or 63/37 be about right? And lead or lead free? Lead does t bother me at all just prefer best bang for the buck to do the job. Just little things like that and cable connectors is about it for now lol.
