Re: Power output on 20 meters.

Hi All,
?
I¡¯m getting closer to beginning the build on my 20 meter unit.? My 40 meter version is working pretty well, except my power output is only slightly over 2 watts.? I assume I need to do some adjusting on L1 through L4.? I tried to measure the inductance for each as I built them, but the LC meter I have was struggling to determine that low a value.?
So, I don¡¯t know what values I actually ended up with.
?
Reading about all the adjusting that is going on with the 20 meter units makes me wonder.? For those who are seeing improvement in power output, are you getting closer to the values stated in the manual, or is this adjusting the values themselves through trial and error?? If success is getting closer to the values stated in the manual, I may try and find a better measurement tool before installing.? I guess I¡¯m assuming the stated values are considered to be preferable, and that they were determined by calculation rather than trial and error.?
?
Here is another question, and probably a dumb one.? My LC meter has difficulty with low values.? So, what if I put something of low value in series with a higher value that does measure?? Will the difference be more or less correct, thus giving me a read on my lower value component?? I¡¯m guessing the answer is no, or not necessarily, but thought I would ask!!!!
?
Cheers!
