Now, let's make a field test.  1 mile up you favorite dirt road (with chuck holes). Set up where there is a good tree to string a wire (your favorite kind). Set up radios, turn them on. Collins- won't work no AC, HW101 Won't work No AC uBitx works connected to car battery.  Winner and still champion out in the field: uBitx!

 

That's kind of a fun comparison. Things have sure changed in radio.  The uBitx is pretty darn affordable compared to any radio!

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!

All,

When I connect USB to the Raduino to rewrite the firmware, should I connect the Raduino to the uBITX main board or take the Raduino off from the main board?

And if the Raduino is connected to the main board, I suppose that I should turn off the main board anyway, right?

Thanks for your help.

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?

Just starting to put together a v4 board.

I am hoping the audio is acceptable and have only considered the AGC mod as a start. Lots to do first. The HF signals webpage which suggests checking the bare boards quiescent current prior to wiring has not got me off to a good start as Farhhan  has now suggested this could damage the board?

I have noticed  both the 2.8 and 3.2 Nextion displays show a 3mm blank strip which is not part of the "active area". On some demo programs a programmed matching strip is left "blank" on the other edge to balance things up leaving an even smaller usable area. Alternatively I could machine out a reduced viewing area and attach the screen from the back on a 4.2mm backing strip so the screen is flush with the metal case.
What have others done to best accommodate one of these screens?

Don,

The WIRE-UP instruction of hfsignals.com 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: Ubitx versus other rigs

Gordon Gibby <ggibby@...>
 

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.

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?

Bigger Nextion display?

Stephanus K6NG
 

I am mounting everything in this recycled receiver and is wondering if i should go with bigger display or maybe two of the 3.5's. The latter means i will have to relocate the vfo knob.
Another option is to mount the 3.5 enhanced version expansion board below the screen and use the for the band select, band up/down and mode functions.
This is still a work in progress and the cut-out will eventually be filled with a bezel of some sort. Probably do a vacuum form insert for it.

It sounds like the raduino has been wiped. You will need to upload the code to the raduino again. You can find the factory code here--- https://github.com/afarhan/bitx40

There have been accidents reported that resulted with the raduino reverting back to a blink sketch, or just blank, no program. I think you are doing a lot of unnecessary things to get this working, and that is causing your problems. It's usually much easier than this. Although I did have an accident that required me to reload the sketch and change it to bypass a damaged I/O cell on the nano.  I have since replaced the nano in order to use Allards newer sketches that used that blown out pin on the old nano. 

You may need to get the CH340 usb chip driver to program the nano if you haven't done that before.

Hum.....the build instructions say NOTHING about plugging in the raduino BEFORE the current test.  So I didn't plug the board in -- and did the test per instruction. 

If if this is an important caution, why not just say..."plug in raduino then do test".  Why leave us to guess and be stupid? 

So so I was stupid. 

Re: Nextion display cutout and mounting. #ubitx #ubitx-help

Hi Dave and others using the Nextion display.

Nice to know all is running well.

However, did you do anything about the 3mm inactive strip along the RHS or did you mount the screen with a slightly smaller cut-out to the screen size? Perhaps you have not bothered about this at all?
I take it you got everything up and running using the supplied display first. I have the 2.8 and 3.2 displays available here.
Any issues with transferring the firmware?
Any tips would be welcome.

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

Not stupid.

It's not in the instructions.
Also, the photo clearly shows no Raduino plugged in.
    http://www.hfsignals.com/index.php/ubitx-wire-up/
Seems Farhan wrote that 7 months ago, and this has all since slipped his mind.

There's nothing that would be damaged if a uBitx main board were powered up
without a Raduino plugged in.  

Looking at the Raduino connector on the uBitx main board schematic near the bottom of this webpage:
    http://www.hfsignals.com/index.php/ubitx-circuit-description/
there are signals for  T/R, TXA,TXB,TXC, CLK0,CLK1,CLK2, CW-KEY, and CW-TONE.


The relay driver at Q15 for T/R won't have any current going into the base,
so that transistor won't be on.  The rig will not be trying to transmit.

Likewise for the LPF band-switching relays at TXA,TXB,TXC.
Though if some of them were on we don't really care.

Perfectly fine that the three clocks are dead, that won't hurt anything.

CW-KEY won't be unbalancing the first mixer because there's no current going in there.
Doesn't really matter anyways because T/R does not have us in transmit mode.

CW-TONE is fine if there's no current going in. 
And would be fine if 5v was applied there anyways.

You might think we could have damage if T/R was somehow injecting current
into Q15, which would power up the transmit amp with inappropriate LPF filters selected by the relays.
However, with all clocks dead, won't have any RF energy going out anyway.
And if there was RF, the IRF510's powered at 12v would be fine (at least for awhile) with the high SWR.

I'd recommend you follow the WireUp instructions as originally written up.
Follow the example in the photo, and do not plug in the Raduino.
I don't see anything wrong with that.
If it were a problem, then we would probably have lots of failures when
blowing new firmware with the rig powered on, no reports of such failures.

I'm much more concerned with the false sense of protection from reversed supply leads 
provided by the recommended reverse diode and no inline fuse, that's a recipe for disaster.
We have several threads on this, search for "reverse polarity" here:  https://groups.io/g/BITX20/messages

Re: Soft for mBITX transceiver

Ian (KD8CEC) made it super easy to (re)install the original soft (firmware) for the ubitx.
Follow his instructions and download 'xloader' and the original soft/firmware in his website page and simply 'upload' it into the ubitx.
You will now have the original software, as shipped in your ubitx.

Different Tuning Steps #ubitx

I want different tuning steps.   I wanted larger steps to, for example, to help moving from one WWV to another.   Below is what I changed.  When I try to set it to 100000 the display reads -31072 and when I accept it the display now shows 00000 ST  I under stand it will only display 5 digits but I could get by with just an S instead of the ST or take the M from the upper frequency display.   I am just a barely an Arduino hobbyist and I know there are some Arduino Pros here.   Does anybody have any ideas?   Thank you for the help.
