Re: Black rectangles - Bitx40 hardware or software problem?
Aha. See my post a few minutes ago. I had the black rectangles on power up, although I was not sharp enough to notice if it was only the top line or both lines, then the display went blank. So wherever your solution lies, I think mine probably does too!

I completed my build yesterday, and powered it on this afternoon. No joy.?
Instead of a frequency display, I got black squares, then the squares disappeared and the display went blank? We checked the power, there was 12 volts everywhere there was supposed to be. So I searched this forum. Seems I am not the first to encounter the black squares, although nobody else mentioned the display going blank. There is a thread that was started in 2017 about the black squares and had some posts as recently as late last year. There was a suggestion that the Raduino was displaying squares because it had not been programmed. Hard to believe that a unit would have been shipped by HF Signals that had not been programmed with the generic sketch because the web page says it has all been tested: "The assembled boards are then DC checked and a final RF check is performed to check the receiver¡¯s sensitivity as well as transmitter¡¯s output before being shipped."?Some folks vaguely suggested all the files needed were "on this site," but others responded that the problem was too many files, many of which were out of date. In fact many of the responses suffered from incredible vagueness. But the main suggestion was to install the amunter sketch (Allard), with a link to Github. The link was out of date and returned a 404 error, but I Googled and did get to amunter's Github page.
I have the Linux version of the Arduino IDE installed, but found nothing that looked like a file I could I could load, compile and install to my Raduino. There were references to libraries and "include" files that were not there. i do not see what I am supposed to do with what is on the amunter Github page(s). I do not want to make hardware modifications. I just want a sketch that I can compile and install to an unmodified out of the box bitx-40.
If you have encountered the black square problem and overcome it, please respond, either on the forum or by private message. Also, thoughts about why the display went blank after displaying the black squares. I really don't need more vague suggestions as in the 2017 thread, I am sort of looking for a cookbook step by step solution! I have to believe it exists!?
Thanks!

Randy, please DONT give power supply morethan 12or 12.5v If you have 13.8 only, try to? put two diodes 1n5408 in series and connect on positive line in series. While taking loD it would reduceto 12.4.? The best is to Djust 13.8tosay 12 or12.5in supply itself.
Thanks for the reply. I just happened to have a spare LM386 on hand so I put it in and it solved the problem. Not sure why the first one went though.

The volume control should be preferably LOG or 10KA

Re: Shaking my head in disbelief....
Playthatbeat Mrdjp: I noticed that as well with the wires and connectors.? Luckily I had red black and green wires of 22 gauge and larger for use with my build.?
On the front panel board I didn't use the relimate connectors, I used the right angle pins supplied with Sunil's kit (the Nextion display enclosures). And thank you, I remembered a couple of items I need to check; my grounding of the ubitx circuit board to the case needs to be verified also. Thanks everybody for the ideas. I will systematically? address all of these in the morning? when I go out to the workshop

Dave the reason you were told the yt100 won¡¯t work with the uBITX is because the FT-857 and other radios listed talk directly to the tuner via the interface cables to activate the tune function.
The uBITX doesn¡¯t have that capability within the various software/firmware that is presently available. Now if you can write a Arduino sketch that can duplicate the tune function of the FT-857¡¯s then all you would need to make would be the interface cables between the uBITX and tuner.

I tried the ldg yt100 hooked to a ubitx.
Wrote to LDG and one of their engineers said it wouldn't work, to my disappointment.
So when I see a thread that talks about using LDG auto tuners, I butt in. Still hoping that someone has a work around.

Re: Shaking my head in disbelief....
When I assembled mine, it would would tune the opposite way than I intended so don't feel bad. To prevent damaging anything when by re-soldering the wires yet again, I used a miniature flat-head screwdriver to remap the wire connections on the plug side. Pressing the exposed tang on the side of the pin allowed its removal.

I am thinking the rig will not make much noise into a dummy load - the gain is purposely low.? So do try your normal antenna, and try headphones as well as speaker.?
As delivered the BFO may be out of alignment.? Perhaps another v5 builder reading this can suggest a starting point value for the BFO.?
Don't be surprised that many of us have a little struggle getting their rig to work when first turned on.?

my connections but something's wrong. The encoder is not working as it should as I rotate it will hop into a menu, almost as if I had pushed it.? I can salvage another from my other projects and try to fix it. The other two things are initially? I had very
low audio and by poking around the wires from the volume it went from low to very loud. I verified my connections and resoldered volume wires again, but same result. It seems that the entire radio might be in need of shielding or maybe snap on ferrite beads.

Hello
Which HMI file.
There are only two files.
The correct firmware for the Nextion display whihc it seems you have
already loaded.
Then the correct firmware for the Ubitx.
That's it.
No reason for you to to be in the Nextion Editor at all.
I can do a video for you to help you but wont be until tomorrow
