Thanks Larry.
How do you keep the spacing of the holes
exact?
I have a "homebrew" table that attaches to my small drill press. The table
has a fence and a stop. I use spacers (plywood strips)stacked against the
stop. I drill a hole and remove a spacer, reposition the work, drill a
hole, etc..
Since the handbook says the antenna tuner is good
for 250 watts of AM, I would need to at least double
the size of things, from the #14 at 8 tpi, about
a foot or more long, to ?
#10, or #8, or thin copper tubing?
I have built coils using #12, #10, #8 and using copper tubing, using the
same construction methods.
Balance is important, maybe hard to do with
a home brew coil..
Why?
I did not study the text, not sure if its supposed to
cover 160 meters, but if I built one, might
as well include 160...
You just doubled the coil size, if it wasn't designed for 160...
I know I will need to make some sort of coil
form/support to achieve a good balance.
