Many thanks ? ?? Tried your suggestion,? alignment screen comes up but still no response to conrtols other than volume. ???? Dave c?????? GW0NVF

Everything is fixable Ralph.

The first thing I would check the tools menu.? You have nano selected under the tools/board tab and when you click on tools/board info you get a window come back that shows that you have pinged a board. Mine always comes back and says something like unknown board at such and such address

If you get errors it is possible that it is the cable. Have found some usb cables which carry power but won't work to load data or not without errors. I doubt if anything is damaged. .?

If worse comes to worse program a second nano and swap it in. Is your nano socketed?

I got curious and checked on the Nextion web page.? Seems there is a new version and an LTS version.? You might want to try the LTS version to see if that one can compile the 2.8 files.

Is there a way to get older versions of the nextion manager? I did noticed that it said that the file was created under an older version.?

After building the uBITX 5 I needed something to house the little electret mic cartridge that came with the kit. I had an old D-104 with a dead element hanging around, so I decided to use that. I get great audio reports from that 10 cent element. The microphone is now bigger than the radio, but it's fun to use. The uBITX drives a Ten Tec Titan II to about 500 watts p.e.p. on 20 meters - more lower and less higher. A lot of fun.? See the picture:

If you go to Ashhar's git hub site and see from the filename that it is an updated version for a version 6 transceiver just download it to you desktop as an example. Then open the Arduino IDE GUI development environment and use File --> Load the filename and when you get it into the arduino IDE screen it will allow you to view the source code and text etc but when you have the usb connected to the transceiver nano comm port it compiles it and uploads it to the nano then transfers control to the nano if the bootloader is there. Just one note you have to puth the original downloaded file prepared into a folder with the same name as the fielname for it to work. maybe look back in the groups.io messages archives to find the instructions for doing that.

It doesnt work with drag and drop directly you download the github offered file then ensure it is set up in the properly named folder and then point the arduino IDE GUI interface to load or open it. If say you are troubleshooting something and say Reed sends you a hex file with the fix incorporated in it you would save that email attachment to your deskto say, and use the Xloader program gui to send it up to the nano directly without having to go through the arduino ide wui.

no drag and drop isn't part of procedure. Just tell arduino to open/load the file as if you were going to custom code it but don't just then jump to compile/upload to the nano directly. If cable hooked up status message should say upload successful? then disconnect laptop usb cable and do power off reset of the uBITx if all goes well the colored screen should pop up with labelled buttons. do the calibrate and BFO zero beat procedures and it should be off and running. Beware the tuning know is also a momentary push button switch that acts as an ENTER key as it were. If you hold it in on power up it usually will enter the setup screen. If it came up OK to the colored menu and you want to enter the set up menus press the tuning knob to engage the switch and hold it maybe 15 or 20 secs possibly and the display will change to the setup calibrate menu then just follow the prompts.? remember if you want to measure power out levels it has to have a tone audio input of some sort or be in CW mode and you should have it connected to a decent dummy load so you don't interfere with others or cause damage to the finals because of a mismatch.

The USB on the nano board doesn't normall talk to the internet out of the box you have to download and prepare the file then upload it into the nano via the USB port using the Arduino IDE you have installed in your laptop or dektop PC to do it.

Thanks Andy, that is helpful.? What I was looking for was instructions on how to apply the latest version to my uBITX.? Do I need specific software (IDE?) or am I just downloading the file, and dragging and dropping it somewhere?? Maybe extract form the zip, then drag and drop.. I don't know.? Not planning on editing the code at this point, just want to know how to get it onto the uBITX.? Maybe if I plug in the usb and download the latest version it will be more obvious?

GigaParts has the uBITX V6 full kit for $209.? That includes shipping.? I purchased one
and it came quickly.? Its firmware is version 6,1.

Some thoughts that may help.

1? As Mark says, 800mA without modulation sounds about right, you will be able to detect some residual carrier (carrier leakage) on a nearby receiver.? This will give you the peep you are talking about.? As Evan says check the CW/USB setting.? Measure the current and output power in both CW and USB modes, post the results here.

2? I would not start with checking the transmitter, you really need the receiver to be working correctly first, it's especially important the BFO frequency is correctly set, this has to be done using the receiver, the links Evan sent you are the ones you need.

3? My guess at your fault, and it is only a guess, is the that the BFO is off slightly and there is something wrong with your transmit audio, maybe the? microphone ot connections BUT with you having limited test gear it's difficult to tell.? You must get the receive correctly first.

On your power input, do you have a fuse on the incoming supply???

Hope this helps

What are you using for a power supply, an unfiltered power supply is capable of putting rf into the radio, locking it up.?

I had similar issue when trying to compile for the Enhanced display.? I believe it has to do with the updated Nextion editor, though I could be mistaken.? I was able to load one of the previously compiled tft files for the Basic display onto a microSD card and then transferred to the display.? The Enhanced tft from the same GitHub files did not work on the Enhanced display, not sure why.?

If I were to guess, I would bet that one or more of the routines that the Nextion screen manager uses has grown, and the display was maxed out under the old development, so that when the original files are recompiled there is not enough room for the application.

Above are just guesses, I have not gone back to the older development environment to verify that.?

On the read me of that zip folder it tells you how to place the file folder and rename it. I did mine the other day following that read me ?and it worked. But i did not use arduino to load the file, i used xloader to load the hex.?

Well a bit of a back story ?i just got my ubitx v6 and after messing with it for a few days decided to do the nextion conversion with the cec software.?

Here is were i ran into issues. The screen i got is a 2.8 basic?NX3224T028. I found the software on github and downloaded the files. Now when i open the files on the nextion program when i either hit compile or load both with the screen connected and disconnected i get an error. I do not know the exact error from top of my head but it was along the lines of insufficient ram. And it referred to the page with the qr code. So i deleted it and then it started giving me an error to a page referring to the url for the qr code. So i deleted this line. After that i was able to compile/ load the file into the screen, and everything seems to be working fine, except i do not have the qr code backup option(because i deleted it).

Has anyone ran into this issue, or know a work around this? I think it has to do with the size of the information on the page, but i do not know were to start.?

I also tried this on different files for different size screens and they all gave me the same error. I got the files from:

cannot get any of the controls to respond just get start up screen volume will adjust? nothing else will reaspond

You might want to set up a git hub account for yourself. It is common developer collaboration type system for collaboration. Ashhar has a github account where he posts his latest versions (busy a lot so sometimes it takes a bit of time to see an update. Reed also has his. If you download theirs' or anyone elses custom codes the full file (ie .ino may be inside a zipped archive) is what you need, although you can sometimes just upload a hex file into the nano but with hex files on a windows PC you need a program called Xloader I believe it is called. It will upload a complete hex file into the nano. If you are working with the .ino main file then you want to use Arduino IDE software package to be able to open it and view all the associated modules and code. Once loaded into the IDE package and you are happy with code changes you made then you can use that IDE WUI to check basic compile syntax and compile it uploading the compiled package to the nano from the IDE. You can also choose option to export complete set of project files (ie .ino master file and associated hex files to save them.

It appears the guys have a file naming convention that describe version info in the files they offer out to those using the git hub account.

So in short to be able to work with code at whatever stage of file you have;

1. download and install Arduino IDE developers package

2. download Xloader

3.set up a git hub account for yourself if you are planning to code a lot and maybe collaborate with others

If someone emails you an att hex file save it to your PC and point Xloader at it to install it into your nano:

If you get or are comfortable developing your own or making changes to an ino package you download from others' git hub accounts they save that downloaded file and point Arduino IDE at that file to load or open it to view code modules or make changes of your own; then compile and upload to the nano and or back up the work as a exported file set.

Hope this clears things up a bit.

As far as loading the software into the nextion the best way i found is using an fti cable. In my case i used my baofeng programming cable. I just ran wires from the jack to the nextion temporarely. You only need to connect tx, rx and ground. To the cable and 5v and ground to power the screen.?
I am planning on sourcing a more permanent solution so i can load the screen software while its mounted on the case.?

Looks to me like black is ground (sleeve), yellow (tip) is mic, and red is PTT (center).
