Oh my, I feel for you. ?
You could try downloading the original software, on a fresh microSD card, but I don¡¯t know if it will work with the display you have, I don¡¯t know much about those displays. ?
Otherwise I think it¡¯s a process of trying to check and see if each oscillator is present at an expected frequency. ? That could be done with a general coverage receiver of some sort, with a wire probing or listening to the isolator outputs, even just making a small coil and holding an inch away from the Si5351
It¡¯s been a while since I used one of the UBitx series so that is about the best I can suggest. In the long run you are probably going to want to learn how to use the integrated development environment and understand a bit about the code.
Others may be able to give you much better advice

?I received my Ubitx v6 a couple of weeks ago.? I assembled it and I did make two contacts.? It did work.? I bought an enhanced 2.8 Nextion board and installed it.? I have no background in programming or electronics, so it took several attempts to get KD8CDC firmware 1.2 loaded.? All the controls seem to work fine but I do not hear is my usual noise floor.? I did not hear anybody. ? I connected the antenna coax to another radio and it works fine.? I connected my TinySA with a 10 dB attenuator and saw no signal on the screen.? I tried different bands.? I connected the same setup to one of my handhelds and saw a signal spike right where I expected it.? Finally I connected a wattmeter to the ubitx v6 and did not see any power out put.? I tried both USB and CW.? I then connected the wattmeter to my handheld and it read 7 watts as expected.?
I then thought I may have screwed up the calibration somehow.? I have spent the last three days googling and reading messages in this group.? All threads have lead to dead ends.? I have tried to hear WWV at 10 MHz.? I hear absolutely nothing.? Same at 5 MHZ and 15 MHZ.? Works fine on my other HF radios.? I tried to tune in an AM radio station.? Nothing.? I read that I can use my NanoVNA or my Tiny SA to calibrate the ubitx v6.? I am already way above my paygrade and don't know how to do that.
Needless to say I am very frustrated.? I don't believe I bricked the ubitx, I am just not smart enough to figure this out on my own.? I don't know if this has any relevance.? My ubitx v6 shipment was delayed over a week because they found a "bad batch of coils and the boards were not passing their tests."??? Like I said, it worked when I got it.? I would appreciate any help I can get.
