Steinar, Graham is right, the coil may be to small for a small amateur antenna. Why using such a big monster tuner? Because it is commercial? We have only 7 kHz of spectrum and assuming "normal" sour
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
Steinar, Instead of a HF SWR meter i vote for building a simple RF amperemeter. Resonance <=> peak current (except you're using a class E PA). Works on LF and MF! 73, Stefan Am 30.10.2012 22:27, schr
Hi all, Is there anyone out there who is familiar with this antenna tuner? https://dl.dropbox.com/u/16381257/2012-10-29%2023.49.15.jpg https://dl.dropbox.com/u/16381257/2012-10-29%2023.49.36.jpg http
Steiner That looks a little 1.6 MHz ish to me .coils may be not big enough . could be the 500 variometer is missing from the space ? could make a auto transformer , next need a series coil of sorts ,
Depends on how much power you are going to use ..... 50 / 70 watts , you can get away with a big version of a top band tuner , parallel tapped tuner .....over this voltage / flashover becomes a probl
