    Efficiency of amps

    Take it A is best and C is least efficient correct? And Ameritron amps fall Under which and heathkit SB-220 falls under?

    Efficiency of amps

    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...

    MFJ-989D versa tuner v

    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)?

    Ft 991 and eco750

    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.

    Ft 991 and eco750

    Now explain the proper way on radio to set and monitor both ALC and Comprssion if your not going to use and ARB-704 box, Just curious

    So I would not go wrong with lead 60/40. So might as well go that way then.

    Soldering

    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.
