I just got the uBitx V6, added Nextion display tested it with external N7DDC ATU, made SSB and FT8 QSOs and already became enthusiastic :-)
I have on my desk an assembled and tested "Chinese 70W PA kit" and will add LPF bank to it. My plan to integrate all of the above into a single box including RTL-SDR as a close loop pan adapter and S-Meter circuit. The ATU display will provide nice display for Po/SWR.
