4.3 Nextion and CEC 1.095/ubitx redo
Hello Mark!! My first dreamy 4.3 Nextion worked like a dream till it went poof. Maybe too many hours on WSPR, so it died of boredom.
I went back to the venerable 16x2 as temp till I could source a replacement? Nextion. In house now, it sits on my bench for a year 'cause I can't figure out all the "load this, then that, stand on your left foot, put your finger in your ear sequence stuff", nor do I now have much of a clue for file locations/versions.? Sad situation to have a lovely I/o device sleeping in the box while being mocked by a two line display.
The fine print on my display says HST043050-A? 2-2, and the box says Nextion 4.3.? All basic, nothing enhanced around here. hahah.?
Could you point me in the right directions to get the 4.3 loaded up?? thanks so much for taking pity on a old slacker. hahahah.?

Re: sBitx antenna-first warning
Many of these ADCs are more expensive than a microcontroller board like the Raspberry Pico. The challenge with Arduino/Pico is having to deal with yet another source of RF spurs. - f

Re: Funtronics uBitx digi interface installation in V6
Hi Justin,
How do you run CAT control and digital modes just using the Raduino? If this had been documented as an option in one of the places I had been reading I probably would have gone down this route.
The Funtronics digital interface board (thread title) is not a keyer.?
The digital interface board should provide audio I/O over USB, as well as CAT control.?
This is something I have been into the idea of since I have been struggling with using the computer's sound card, since all of my machines have a single combined mic/phones 3.5mm jack, and Win10 is not happy with enabling both at the same time.

I bought the "Discovery" model Nextion. Using these will involve loading the Nextion Editor and changing the screen setting, then correcting the error it generates to do with the newer Editor (the error reports what page it is on, and a number needs to be changed to 78 for it to compile).
I don't know if there is a benefit to the Discovery screen, so I would recommend sticking with the Basic or Enhanced.

Re: Funtronics uBitx digi interface installation in V6
Your friend is happy with his ability to make thousands of contacts mechanically. I think that trying to improve him and his ability would be a waste of time. If a hobby is doing what a hobby is supposed to do for a person just leave them alone. ?I have a few friends that use their CW decoders all the time and they are happy collecting countries and wall paper¡.. they just do it differently than I do. ?I found the same with RC airplanes¡.. some buy their planes already built and others build and repair their planes themselves¡. They both were happy with their hobby.

David, this is really, really sad. Your friend is missing out on so many things -- the thrill of learning and developing new skills, the joy of conversing in a new language, not to mention the brain-building and brain-health maintenance that CW provides to its practitioners. And one more loss -- I, for one, will NEVER have a meaningful QSO with him. -- Rich WB2GXM last point of my opinion, and i apologize if i come across as a hater,but im not.
Friend of mine is a no code ham. he learned the basics of the code and uses a decoder to decode the cw. he sends about 20 wpm with his paddle ,which doesnt make sense because he cant copy past 6 wpm with his ears. i proved this with on air copy. doing about 8 to 10 wpm. he said he couldnt copy it even though he sends really fast. he doesnt try to decode the cw in his head since the decoder is doing it for him. I told him if you can send 20wpm you should be able to receive faster than 8. no way. i had 3 other hams verify this. WEIRD,BUT TRUE.He stated"why learn to copy faster when i have my decoder. he uses software to do this on his not knocking him,but i did explain the reasonings of not using one.happy he is trying cw and using it,but the decoder gives him a false sense of accomplishment. he has been using this setup for several years and still cant copy faster than about 6 wpm. WEIRD ISNT IT. My friend is an engineer for 30 years, very very smart, but has been ruined by his decoder. HI HI.3 of us have been working with him with various,various methods, and we even paid for his classes,etc just to be friendly. he went,but the instructor stated "ive never seen anyone who can send 20wpm and not copy by ear at least over 6 wpm. He refuses to try to fill his head with the decode but can send 20 wpm with his paddle. foud out some of his secret. he uses precanned groups of statements. qth,radio,rst,etc. He goes thro the motions and then after his decoder decodes the other hams info he clicks the statements he wants sent next,it also includes the 73,etc. .very canned,very brief, using decoder and software on computer.? is he running cw? yes,but with an analog radio and no goodies attached to it,like a decoder,he is dead in the water without it.Ive praised him over and over for trying CW,but He stated "i can make 1000s of cw contacts and basically not even know CW"The computer and decoder will do it all for me.His words,not so his paddle is basically for looks. he uses computer control to do the sending 99% of the time.
please inform the other end u are using one if you cant decode the signals when adjacent qrn,qrm,qsb affects it or you are in a is leads to abrupt endings of qsos. or qsos that really seem robot operated.I ran into this when doing ft8.

Mark, Go ahead and do it. You have two safety nets. First, the original sd cd image is on the gdrive link on (it is too large to be on github. Second, you can make an SD card backup from the menu (I dont remember where exactly it is). Or you can use the venerable dd command (look up the usage on rpi forums). Except for the config.txt, I don't see why apt update should change anything. Try both.
My sbitx basic kit arrived today and works perfectly (sbitx #77 is on the air as I type). I'm keeping it under 10w for now until I replace the voltage regulator, but so far so good.?
The linux admin in me wants very desperately to run an apt update/upgrade on this, but I wanted to make sure first that the currently sbitx software isn't relying on the specific versions of anything that were pre-installed on the sdcard that was shipped with it. Is it expected that we would maintain these as any other raspberry pi and perform that update?
My intention is to have this connected to the internet and remotely accessible so I would want to apply security/bug patches from the apt repositories regularly.?
