as you know the optional module of ATU is under finishing and the f/w code under tweaking for the RGO ONE.
One of the hardest point of the ATU performance - the very low impedance matching has been successfully tested on the beta test piece of RGO.
Look over here: https://youtu.be/aImge42dZZk
The antenna in use was an 80m band dipole. Tested band was 160m.
The ATU f/w code is still under tweaking and hardware is in beta testing to be sure that all will perform excellently in RGO ONE.
