Well known and good designed ATU by N7DDC-must have for all field day fans and poor antennas ;)
btw, I don´t understand people when saying ATU is must have for portable operation????
Hey, you are outside...and you can make practically any antenna -dipole, vertical etc...to be perfectly
matched to your RTX, especially when you have- and know to use antenna VNA. Nowadays they are cheap and affordable!

Kit from ebay...cheap and solid kit without display
Coil check with home made LC measuring device
Simple and well documented project...
After pic programming all is working fine...even oled display
Mounting in my HiQSDR RTX
Making the nice looking front panel is always a bit problematic in
homebrew equipment...pfff not so nice but...:(
Display is mounted without screws with Al and Cu tape,
its good for shielding too!
Ole...finished ....but this is -not- the final look of my HiQSDR RTX :)
One button configuration is working fine, but 3 button version is better-
so, i will mount plus 2 buttons later...
My stationary end feed antenna is fine tuned...so i don´t need ATU at all...but its nice to have
some PWR and SWR readings on radio front panel.
