What are you getting on the nextion, as is? Is it booting?

Hi Bill,

Best bets are ?or ubitx.net

They both have tons of info and downloads.

As I said a royal pita. In all my stuff I only found 5 SD cards,
2 full size 1- GB , 2-128 GB wont read, 1-16 GB which I reformatted numerous times.

With just that last file, it should work. Might be a bad sd...but, your computer sees it. Odd

At first I only had the last file .

Is there a file (tft) for the Nestion 3.2? (NX4024032) I have a V5 board also what hex file for the firmware?

Thanks Bill K9JUI

Can you send a screen shot of what you have on the sdcard?

Here is mine...I have a handful of files on the sdcard, but the nextion will only read the top one cause it's .tft

I changed the others to xtft or oldtft. The nextion should skip over it.

fat32 on a 16 GB micro SD, I tried 8k 16k 32k segments. I have the enhanced 3.5. I tried both basic &
enhanced files .tft . The device states "no found file".
I ordered a new 16 GB micro SD getting it tomorrow.
I'm trying to figure out how to mount the face plate in my Bridgeport milling machine to fit the Nextion 3.5.
Thanks again for your help. Laddie

A new rig can sound different. I doubt you did anything to calibration by accident. Learn how the menus work on your own for all but calibration. Do listen to different bands. Enjoy the rig a bit before concluding anything is amiss. Since you and I didn't solder all these parts, I doubt there are any solder issues.

I use my 817 with the uBitx. I press and hold the tune button until it goes into the tune mode and then I just say “oooooooooooooo” into the microphone and watch it tune up. If you’ve never tuned that particular antenna you may say “oooooooooooo” until you almost run out of breath but it will tune. Once you tune around on a few bands, the memory tune is pretty quick. Never tried tuning with CW but I suspect it would work just the same.?

Well, I connected my windom antenna heard some 40 meter cw, but I also heard some things like birdies and so my first thought would be to check for cold solders, shorten up wire runs, and twist cables to minimize noise pickup. I stumbled into the menu, and I hope I didn't mess something up...got a message of "calibration? set!" But I have no idea how I got there, or w hf at I did.? Stock firmware as shipped on raduino...no mods yet.

? I formatted mine fat32. Did u copy the tft or hmi? ?Is your nextion an enhanced version or basic? If basic, get gthe basic version of the tft.?

Which four diodes, and how are you measuring them?? If you are referring to D10-13, and measuring in circuit with a VOM or DVM, then they will all read ground, no matter how you measure with the DVM.? They are part of the double balanced mixer, so there is always a circuit to ground through one of the other transformers with the grounded center taps.

I do not have a BITX 40, only a uBitx v4 and v5.? These are multi-band versions of the BITX40 design principle, so I might be able to help with theory, however actual measurements will require the help of someone else.

I would suggest that you start with describing the current problem, and some of the background.? The more detail the easier it will be for others to provide accurate advice.

Just suggestions, not recommendations

This should give you an idea of what I have done so far..

I have used the KT-100 and a few of the other LDG's with bitx radios as well as other qrp rigs. You just need a way to give it power and hit the tune button on the front and then TX on CW.
