Adjustment of simple balanced tuner
 

I am new to this type of tuner and am hoping to benefit from other's
experience.

My new balanced tuner has a parallel lc circuit. The output to the antenna
is taken by clips placed on the
coil. A series tuned link is used from the 50 ohm input.

What is a short process for tuning? I have tried moving the taps around at 3
turn intervals and
trying to minimize the SWR. It seems that if I tune the series tuned link
off resonance the reflected
power decreases, but so does the incident power. Ditto the parallel link.

Must I put the tap on each turn of (the large coil) and see what comes out
lowest? Or are there
some "shortcuts". Is it likely that I will be able to produce a match over a
wide range of impedances
with this tuner? My first experiences have been rather frustrating to say
the least.

Thanks.

Allways start tapping at the outer ends of the coil (total L) and try to
find a point where SWR=1.
If you don't succeed try tappping more toward the centre of the coil until
you can get SWR=1 by turning the capacitors.
I prefer the classic Z-match... easier to use.
