Re: NEXTION UPDATES FOR 7 AND 5 INCH - --ADAPTED FOR KD8CEC VER 1.095
Pat,
I am no expert, but I have 3 nextion displays 3.2E and 7 inch.
I have never seen? that type of picture displayed on any of them . It looks faulty.
What is your power source for the 7 inch??
I run my 7 inch on its own wall 5v 2a power supply
Joe ve1bwv
Joe,
I downloaded your code and yesterday the 7in Nextion arrived just in time for the weekend.? But, I get the attached image whether booting with an SD card or not and the Nextion IDE cannot connect to the display if trying
to upload.? I have used these same procedures with the Nextion 2.4 and 2.8 with no problems.? Looks like a bad display to me.? What do you think?
Thanks,
Pat AA4PG
Vern, I usually attached both files..
See attached? - newest 7 inch for non E version. It will work fine on your 7 inch E version
You will be able to compile , just select your display type and size then compile to get your ,tft
It says test only because it has my latest changes as of this morning.
If you have any issue I can compile and send the tft for the non E version as well.
Let me know how it works

Re: Ubitx versus other rigs
Just to play devils advocate, let me point out that I have gotten several SB102¡®s or HW 100s for $100, and their power supply for about the same.
Takes a bit of work to recondition them, replace all the electrolytic capacitors everywhere. ? Particular problems with the mode switch and it¡¯s contacts.... switching 300 V DC isn¡¯t a great thing for a front panel switch.??
If you¡¯re into emergency communications like me, you had your generator with you in the back of the truck. ?Or I have a 2 kW sinewave inverter... we had huge amounts of solar power available at the field day. Ac, dc... either one.
If you take that Raduino, do a little simple reprogramming, it will feed right into those older vacuum tube rigs ?where you stick the VFO signal.. ?Measure all the heterodyne crystals, a tiny bit of math, and bingo you¡¯re si chip ?has become a digital
VFO ?for these rigs.
Lots of times these vacuum-state rigs will put out 100 W, sometimes all the way to 10 m. ?With the raduino , it¡¯s now digitally accurate and digitally controllable. ? For around $250. ? I think you can get about the same power with an uBitx, external solid
state amplifier and a series of low pass filter¡®s (I have a set waiting on me to get to them.), but it¡¯s interesting how comparable costs are to get to this power level both ways.

Re: Basic board test: 130ma @ 12.5 volts
#ubitx
Don,
The WIRE-UP instruction of says ¡°between 90ma and 110 ma¡±.
My V4 was 85.25mA with 12.25V 5A power supply.
I forgot who, but someone here said, it¡¯s better not to power up the plain board for long time.
I tested within 5 seconds only for a few times.

Hello!! New uBitx V4 builder here. ?Instructions call for a plain board power up with no connections beyond power Jack. So I have no plug in cables at all. No ardunio. Nada. zip attached. ?With power 12.5v I get 130ma. ?This is above specs of 80-100ma. Is the extra 30ma due to the extra half volt above 12? Or do I have a problem someplace? ?

Re: Basic board test: 130ma @ 12.5 volts

Hi Don, Ashhar.
I am also starting to put together the v4 board at the moment and am surprised to see on the HF signals (hfsignals.com/index.php/ubitx-wire-up/) wire-up page a check of the boards quiescent current prior to wiring!
Can you clarify as to why this has been left up with pictures on the site if the board can be damaged by doing this?
I am hoping this has not caused a problem.
Having machined out the rear panel I need to work out how best to mount a Nextion display as there is a 3mm strip along one edge not used as part of the "Active Area". Not sure if to make the cut-out smaller or not. Any ideas?

Got it, Raj.
I can program the Raduino standalone or even when it¡¯s connecting the to the uBITX main board.
If connecting to the main board, maybe it¡¯s better not to power up the uBITX.
Thank you a lot, Raj.
Now I will check if the Raduino works well or not, before setting up to the main board.

Hiro,
Switch off power to be safe. If some problem is there while programming then try unplugging the Raduino.
I have not had any problem with programming even with power on the board!

Dear Dexter,
Thank you for your information,
the result did?nt change, there are only light shining display ore bold black signs, nolonger the frequenzies whne I trimm the blue pot

Re: Troubleshooting decoder
Ok. I had the same issue and replaced it with the part from Digi Key that I pasted to this note. It works great now. The encoders are fragile so I bought 5. I tested mine out of the unit with a continuity tester via DMM. The side with the three pin outs is what I used. Center is common or ground or whatever electronics guys call it today. So connect the meter to center and top pin and rotating should show short, open, short, open..... Do the same with respect to the bottom pin and same outcome. Mine was constant open on the bottom pin out. While your at it connect to the pins on the other side and it should act like a momentary switch.

I'm curious what you are using for an antenna or aerial.
I would tune to 7076 (in LSB) to listen for some tones called FT8 (decodable using WSJT-X software). Popular digital mode right now. You could tell if the Bitx40 was at least receiving. It's where most of the 40m activity is around me.
We were writing at the same time last night. I would definitely change the pot. I burned up one wiring the 5V to the wiper that way.
As some other have mentioned, a blue LCD with no writing or numbers may need the contrast pot adjusted. Also would need adjustment if the letters are white blocks or rectangles on blue.
I know I have to take a break for a week from time to time when I get stumped.
Best of luck to you Heinz.

Do plug in the raduino and wire it up properly before measuring the current. You may even damage the board as many digital lines would be afloat. - f
