Hi, thanks for the feedbacks from both of you .


"Why using such a big monster tuner? Because it is commercial?" Hehe,
absolutely not Stefan :) but a ham friend of my gave it to me when he
heard about my 600m transverter project. I will probably take it a pa=
rt
an use it for other antenna projects.

I am now planing to make my own variometer, just for the fun of it. I=
 am
a novice you know , and I have to take the small steps to learn. I ca=
me
across this page describing in easy terms how to make a variometer,
http://www.giangrandi.ch/electronics/shortanttuner/shortanttuner.shtm=
l .
It seems not be too difficult :)
