All of these kits come with little or no documentation, there is plenty of info if you Google it.
I have to say though, that at the price they are, they do work well.
The old adage ¡°you get what you pay for¡± applies

well i now have it showing the things it should on the display,did it by trial and error and using stronger glasses,will test it on my antenna tonight,may stick it in a waterproof case and mount it at my antenna feedpoint,ifit works oki will buy a couple more and mount one in my homebrew roller coaster atu,its just a shame they wasnt sold with all the information needed for the build,spent hours trawling the net and watching vids! 73 de m3vuv.
 

Hi, Paul
ATU-100 is the fully open source project and you can find all the info in one place?


even instruction manuals on different languages.
