Re: 4.3 Nextion and CEC 1.095/ubitx redo
OK, looks like it is time to rev all the screens. The newer Nextion screens that you *buy right now* all require that the tft file be generated with the latest Nextion editor. The good thing is that "at least in the one test I did", the new files work on the old screens too.
Give me a few hours to collect the latest that have been properly sized for the screens. Screens that are 4.3 and below will be someone else's design (usually better :-) and i want to credit the authors properly. Note to all:? If you buy a new Nextion screen, either buy the "enhanced" or the "intelligent" version. (the Intelligent version has more memory, faster processor and multi-media. It is also usually less expensive than the enhanced. The one issue I have not checked is whether the Intelligent version is more RF noisy than the basic and enhanced). The BASIC is like the Nano used on the Raduino,, it has run out of gas and has become a bottleneck to doing anything new. (standby for more on KD8CEC running on newer Nanos ;-) ) To squeeze the current screens into the Basic, I am going to need to reduce the size of the QR code screen to save memory. Know this works on 4.3, but not sure that this is even a viable option on 3.5 and below. 73 Mark |
Re: Sbitx finals replacement - update
Farhan, all
Ok some progress today. Verified that the 12v and 5v are present before, during and after the reboot. I do hear a relay click when I select CQ then the Sbitx stops working and reboots. I assume it is K9 although haven't looked at it yet. Any thoughts - maybe U3 or U4? Can anyone share their opinions on my approach? Art N2AJO? |
Re: Funtronics uBitx digi interface installation in V6
For digital modes on any of 6 uBitx, I use CAT control through the Nano USB port on the Raduino board.? For sound using desktops and laptops running Windows 10, as well as a Raspberry Pi running Buster, I use a cheap audio USB dongle:
Others work as well, including the Plugable brand. The Plugable is for situations where you need stereo mic input.? The Sabrent are mono mic input. 73 Evan AC9TU |
Re: #sbitx mod
#sBitx
Hi Jerry,
Thanks again for the instruction.? I've not had this scope for very long and I hadn't gotten to some of the math functions.? Pretty cool functionality.? It's not the presentation I'm used to, analyzing power profiles for data centers, but it's pretty cool.? The presentation shows the magnitude of the "noise" at various frequencies.? If I'm reading this right, the bandwidth of the noise is from about 100Hz to about 5MHz with the highest magnitude of around 60mVdc.? I'm going to install it in the radio and listen to the performance.? If it's quiet (or at least as quiet as the LM338), I'm going to call it a success and welcome the ability to mechanically clamp the PA transistors securely to the heat sink. Now if my order from DigiKey would just arrive. Cheers, Scott P.S. I have followed Kevin's channel for some time now.? Interesting stuff.? I don't think I could be happy living in an RV but to each his own.? JSM |
Re: #sbitx - an ugprade kit is on the way
#sBitx
Farhan,?
I can't say enough good things about the general idea and features of this radio (and potential features).? The first night I got it I was watching FT8 decodes and had my first QSO (SSB New York to Bulgaria). My sBitx (#69) let loose the next morning during a local 80 M net.? I was running about 25 Watts into a 2.5 : 1 antenna, and having my friends help me tweak the audio levels.? I've been too busy to spend a lot of time with this until last night, but finally did a tear-down and took some pictures.? I wanted to post these shots of my main board to see if anyone thinks I need to address anything else.? I had added an extension cable onto my power cord, and that's what originally flamed out. I have since ordered the recommended power supply and some materials to make a new proper power cord.? It was the next morning when I applied power again, thinking that I had just blown the cable that most of the damage in these pictures may have occurred.? I really appreciate your support of this project and I'm looking forward to getting the upgrade kit. Thanks for any assistance! --Neil, W2NDG |
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.? Don km4udx |
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 On Wed, Aug 17, 2022, 4:46 PM Niels Jalling <niels@...> wrote: Another solution for sending analog signals to the pi is to use a four channel AD-converter such as an ADS1115. |
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. 73 |
Re: #v6 Day 3
#v6
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. |

¿ªÔÆÌåÓýGuys,?This is a hobby. ?Whatever brings satisfaction to your head and a warm glow to your heart (and lowers your blood pressure and helps you tolerate all the rest of the world) when you walk out of your shack is fine and OK in my book. ?Maybe for me it¡¯s just breathing in rosin core solder smoke that does it.

Re: Funtronics uBitx digi interface installation in V6
¿ªÔÆÌåÓýYour 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¡.

Re: #sbitx - an ugprade kit is on the way
#sBitx
tnx a lot for the service. After first attempt to transmit the sBitx went dead but after unmounting the RPI and the display I found out that just the 4A fuse was blown. I am sticking to 5W until the buck converter is installed.? Vy73 de |
