Whatever the default is. I haven’t been able to figure that out yet.  Just been able to find its X, Y cords to move it around. and how to stretch the width of the signal and the hight. It’s not obvious as it uses some math with the sys*x

Re: 2.8" and 3.2" Nextion Enhanced Displays for sale #nextion #ubitx

Still have these -- prices are not etched in stone (only postage is).  Make me a legitimate offer for either one or both together as I'm pretty easy to get along with.  They are both the enhanced versions and both have older versions of the CEC Nextion display software in them.

Re: 5” Nextion LCD files

Yes I painstakingly re-sized everything including the graphics to 800x480 for the main screen and config page. And I reformatted all the other pages and going to refresh the graphics on those pages too ie pdsp.  I wanted to keep the original style but I made a few minor graphic tweaks. 

As of late I have tackled moving and resizing the spectrum screen on main page as well as other pages.  I’m not a programmer either, it was just a fun challenge to take on but quite a few long nights.

Hi Paul.

Given that you have the physical item, and now the circuit diagram, a track layout diagram should be superfluous. Aside from Gnd/0V and +12's, most other tracks (traces) connect only 2 or 3 components - and only one point of each. Inspection and cross-referencing should tell you not only which component does what, but also each track, and practice should drive that into intuition. Just be aware of 'vias' connecting top and bottom layers - they look like small, filled through-holes.
In time you should be able to call yourself a real Tech! Good luck and 73!

Strange BFO frequency #ubitx-help

Andy GI7INR
 

Hi all, Newbie here so apologies if this topic was already covered in earlier posts. I promise I have had a good rummage round to check similar topics before posting.

My v5 radio out of the box does not receive well at all. I’m sure I’ve messed something up, but not quite sure how. SSB stations are very distorted and unreadable on RX. When I transmit CW and listen through a separate receiver it is horrific (loud transformer buzz, continuous tone until relay kicks out regardless of what is sent, ie no dit’s and dahs distinguishable, straight key being used) - side tone feedback through speaker is perfect though.....

I have checked my build, loaded v1.20 CEC firmware and read from the device via the memory manager and attempted tune up both through memory manager and directly on the display per various instructions and videos.

So Finally to the actual question! - I’ve noticed most articles refer to a good BFO setting around 11995/6 or thereabouts. My factory setting was at 11054.160. I am assuming this is very far from where it should be based on all the previous info I’ve read, but before spending a LONG time spinning the encoder to get to 11995 all the way from 11054 in tiny increments, has anyone else noticed such a low starting value from factory? (PS I know this is probably easier to reset via memory manager, but i was trying to tune using original instructions having had little success so far entering a good BFO setting via memory manager)

Thanks for reading, and sorry again if this question is naive or repetitive.

AG.

Re: Bitx 40v3 Diagram

Paul Bigwood
 

Thanks for the circuit diagram. Most useful.

I have a SMD V3 board with a fault. The board has a date code of 0917 which is when I bought it. I never got round to  wiring it up until recently and found it blew the fuses as soon as I powered it up.

Investigation shows a dead short across the +12V main supply. The +12V PA shows between 7M and 11M ohm depending on which way round the leads are, so guess the PA is OK!

I can work SMD OK, but am wondering if there is a PCB layout  track diagram anywhere, to help decide where to try and isolate the fault. I am thinking that D7 has blown from connecting +12V the wrong way round, but don't remember doing that !

Re: Dan’s ubitx

Thanks Dennis - good luck with your build. I used the little add on AGC board that's available, but I don't think it's really compatible with the V5. My AGC unit popped a lot with strong signals, it was awful on a contest evening. I partially corrected it with a 1k5 resistor in series with the audio in on the AGC, but its not perfect. Still pops sometimes. Keeping an eye on the group for a fix...

Re: My uBitx Easy-Digi interface for under $20

UPDATE: Being a digital mode newbie, I didn't realize the CP2102 UART I originally started with would force DTR and CTS high (on) when in RX mode, and low (off) when in TX mode.  This is opposite what most software wants (i.e. WSJT-X, Winlink).  So I have replaced the UART module with the "USB to Serial Cable" which defaults the DTR and CTS signals in the normal manner (low on RX, high on TX).  Cost is about the same, and is a cleaner, more professional look/setup.

Now it works with the aforementioned software (fldigi works either way).  Here's the link to the updated document:

Re: Need uBitX documentation

Rick

it is a bit of a snipe hunt to merge HFSignals and the case instructions.  In addition to any paper you got for the case - check out ubitx.com - they may still have a video illustrating assembly. 

that little LED board is optional - the key matter here is that the wires to this 2-color LED solder to places on the bottom of the main ubitx board - details on paper or at ubitx.com shows where these wires go.  it is trial and error to with the LED end of the wires to determine which puts green on receive and red and transmit - use your DVM as required to ID the common (or ground return) wire. 

I suggest waiting until ubitx is assembled and working to add AGC.  it can be added with the board already in the case. 

HFsignals will have the ubitx schematic and other circuit info - extremely clear info there, but a lot to digest.  determine which version you have 3, 4 or 5 so you get the proper info.  v5 is very recent. 

be patient with mods.  I anticipate your rig may have 'acceptable spurs' on 80 and 20 meters before mods as many v4's do.  some v5's have been shown to be okay on 40m, but have spurs on 80m. 

enjoy your build journey.  my local club members are building more than 23 rigs -- here is our library.  I definitely suggest attention to wiring both sides of the headphone jack, and if you do CW the sidetone level mod here works very nicely.  https://k3pzn.net/ubitx/

Many thanks to all. Did Google and found the vidio on setting bfo, will check that next. If more needed will look into the adding if parts but hope this will do the trick. 

Just needed a push in the right direction, a little worried I might do some damage. 

Again thanks all for the speedy help.

Do a Google search for "Improve BitX40 Audio" by VK3YE. He shows how to adjust the BFO frequency on the stock BitX40 that really helps the audio. You can also make the mods needed to use Allard Munter's V2 BitX40 sketch where he uses the Raduino to control the BFO similar to how it is done in the uBitX.

Hi Farhan et al

I will be arriving late Tuesday night. Staying in the Holiday Inn. Will look forward to catching up with you and any other BITXers or QRP Labbers! 

FYI I will also have with me stock of most of QRP Labs product line, which will be available at vendors' evening on Thursday, and throughout the hamvention on Friday/Saturday/Sunday at the QRP Labs booth 6612.

Try ubitx.com.  Believe that is what you are looking for. Be aware that there is an error in the wiring of the volume switch.   There is a thread below that discusses this.

Need uBitX documentation

Rick Green
 

Hello,
I recently purchased a partially-assembled uBitX along with the 'Universal case' designed for it. Also included is an AGC board from kit-projects.com, and a 3.25" Nextion display.
Unfortunately, the only documentation I got was a several page manual for the case kit. I've found the basic docs on the hfsignals.com site, but I'm still looking for some additional pieces to the puzzle:

1) Schematic and assembly instructions for the tiny LED board that came with the case kit.
2) Wiring and installation instructions for the AGC board. I see the pictures of the PCB board trace to be cut, but I can't find any info on how to wire the switch, the RF gain pot, and basic power and ground.
3) How do I integrate the Nextion display? The case kit came with an alternate front panel with a larger cutout, but this display doesn't have the same connector pins on the side, so it's clearly not plug-n-play.

Can anyone point me to web sources for these missing pieces?
