Joe,

I get the same result with power from USB, uBitx, and separate 5VDC supply. I have requested an RMA to exchange the display (Robotshop) but I'm pretty sure?it will be next week before I get a new one at the earliest.

Thanks for the reply

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

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

Gordon Gibby

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.

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.

Re: Basic board test: 130ma @ 12.5 volts #ubitx

 

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?

Re: #arduino #arduino

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.

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!

Re: Troubleshooting decoder

Mike aka KC2WVB
 

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.

Thank you for placing your order with Digi-Key!

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.

Re: Basic board test: 130ma @ 12.5 volts #ubitx

 

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.
