Bonjour,
The proper setting of the BFO is very important for output power as well as for receiving, it seems.
I would suggest setting this to 11,056400 and see how the output power is on the bands.? I have one V5 set for 11,056560 and another V5 set for 11,056210, so my suggestion here is about the middle of those.
After this, if the output has improved, one might find an audio spectrum graph application (or the HF Signals web page tool for the purpose) and find your specific BFO value that performs the very best on TX and RX alike.??
Bon chance,
Ted K3RTA

Re: uBitx microphone wire up
It’s not an idiots guide, it’s a learning process. We’re all going through it, some have just started earlier. I went through this exact issue about a month ago.?
Best of luck. Enjoy!
I hope we get to talk on the air.

Re: Ubitx V6 Nextion 2.8" Display Modification
I used this guide to get started but off from this site I was able to find the later releases:

When I downloaded what was there I could not get it to work with my 2.8" Enhanced display.? I also could not get the source to compile, as it said that there was not enough memory.
I am new to the Nextion editor, so it may be something simple on the settings that I do not know about.? I have built 3 units, a 2.4", 3.2" and now a 3.5", however all have been from tft files.? I did not have the issues that are happening for me now.

Greetings to all. I have two BitX40's in Universal cases for sale. The first is built and ready to go in the Universal Case DA Grey I and the other is unbuilt with the Universal Maroon Case II. Both BitX40's are stock and unmodified...I have loaded Allard's v1.29 firmware on them but can also load v2.04 if you prefer...$100 each shipped. CONUS only. PayPal preferred. Thanks for looking.

Hello,
got my ubitx v5 one month ago, almost finished ...
it's sell with "More than 10 watts up to 10 MHz, 7 watts up to 21 MHz, 2 watts on 28 MHz" ,
i get 2w between 21 an 30Mhz, then the power drastically decrease under 2w under 21mhz, around 800mw at 7.1mhz, and close to zero on 3.5mhz
what's happen ? it's should be the opposite.
i have already checked and re*tuned rv2/rv3, my microphone is a baofeng, test with cw give same result
i want to operate mainly on 20meters, hope 5watts, should be nice.
any idea ???

Re: uBitx microphone wire up
Fantastic! Thank you Mike!
Sorry for needing the idiots guide.

Whoops! My error, now discovered. Nothing like making a post for help to dicover the problem on you own!
I assumed I had the latest DSPMeter sketch (v1) but it appears by looking at the upload dates that (v0.8) is a later version by about 11 days. I guess I didn’t understand the naming convention. I have now installed v.08 and I am getting good SWR indication.

Would the (now discontinued) CW Conditioning Board help fix this?? Seems easy enough to home brew this circuit.? Still waiting on my V6 to arrive, but I'm a CW-only kind of op and keenly interested in this.

I read your post that you have the SWR function working on your uBitX. I have a V4 that I built a year ago and added the Nextion display, then added the second I2C Arduino and I am able to do all functions with that including CW decoding, audio spectrum, S-meter and so forth. All has worked well for many months. In order to eliminate taking a separate SWR bridge for use with my loop antenna when going portable, I decided to add the SWR bridge in KD8CEC’s website. I built up a Stockton bridge and I am measuring good results with itI, with FWD power in the 1.7v range and maybe around 0.5v in the REV pad in a typical check. SWR caculations by hand match actual SWR pretty well. I wired the FWD and REV pads? to pins A2 and A3 on the second, I2C Arduino and on transmit I see nothing…no deflection of the S-meter graph at all.
Did you have to do something different that just connecting the 2 wires? I didn’t run a ground wire as the SWR bridge is already connected to ground through the antenna connector, and the second Arduino is connected to its own ground as well. Is there a switch in software? ?I am using version "UBITX_CEC_V1.100_NX_S" of the KD8CEC sketch and “dspmeterv1” dated 4/1/2019 on the second Arduino. Thanks for your help.

Legal risks are not something I would worry about, especially at QRP power levels.
Cease operating if you get a complaint, verify your equipment is not at fault before resuming.
If that's too much risk, you'd best stay in bed.
Most of us take far more risk everyday when we get behind the wheel.
Or make our way on foot using a crosswalk.

I wondered the same thing, but apparently the ubitx falls
under the "With Basic Qualification only, transmitting
equipment must be either a commercial
pre-assembled product or a packaged kit designated for
amateur use". Seems a little
grey to me too.

likewise I wondered about? remote amateur systems like echolink
or teamspeak3 granting full transmit access to a basic or

Re: Ubitx V6 Nextion 2.8" Display Modification
I used this one:
Nextion 2.8 inch Display... https://www.amazon.com/dp/B07Q36RBV2?ref=ppx_pop_mob_ap_share
And then loaded the kd8cec code on it and updated the firmware on the v6 to the v5 CEC firmware?

?Bill,
Looking Good!
Now a question and a request.
The question is which Nextion 2.8" display did you use?? The enhanced or basic?
The request is if you could point me to the Nextion HMI or tft file you used for this build?? I have been searching for a 2.8' enhanced source for a build I have in process.
Thank-you and again, good job!

Re: New ham, Ubitx issues
#ubitx
also found this:
“Build” in the context of the Basic Certificate is limited to the assembly of commercially available transmitter kits of professional design.
I think the ubitx falls under that as I read it, but if I am wrong, please show me the way!

Re: New ham, Ubitx issues
#ubitx
I tried to re adjust the two bias pots by following the ubitx guide. It says to first turn them clockwise and measure the current, when doing this my total current consumption in 1.2A (some searching says it should be 300-500mA depending on mods), which is quite high. So I put my meter on the brown power wire only (PA power) and the lowest setting I can get is ~900mA with the bias pots clockwise. Idle current is 0.
I am running the ubitx on 12v.
