Re: uBTIX no signal or reception
First, check your antenna connections inside the rig,then check all other interconnecting cables.make sure they are all installed properly, then
I would re-install your stock firmware and display if nothing else is wrong.
if your receive comes back, you might have corrupted the uploaded file to the ubitx by some weird chance.

Re: One of the coolest smart knobs I've seen.

A good story, though not quite correct.? In the mid 60's,? NASA was using mechanical pencils (possibly leaving bits of graphite floating in the air) and the Soviets were using grease pens.? The Space Pen was developed independently by Fisher Pens on their own dime.? Both NASA and the Soviets bought them in bulk for $2.39 each, have been using them ever since.? The pen has many advantages, and is popular for those earth bound as well.? You can buy one today for around $20.

Re: One of the coolest smart knobs I've seen.

I agree, Jerry. I put a "handle-spinner" on my T41 tuning knob. It stayed there for about 20 minutes. I went back to the old knob which just has a dimple on it. I also used an optical encoder in another test...it last about a day. I actually miss the detents of my cheap encoder because there is no inertia "coasting" after I release the control. To each his own...

Better off just spending more than $0.50 on a good rotary encoder.
Though the $0.50 ones work surprisingly well.

Mornin' Ford:
Al and I have no control over the shipping of the T41 kit and they have not said anything to us about selling individual modules or boards. However, I don't see why they wouldn't consider that. Al and I don't want to get into the marketing aspect of the project. It's a hassle we don't want to mess with. Bill, K9HF, is selling boards for those who are interested.
The advantage of the Arduino IDE is that it supports multiple CPU's, including the STM32, ESP32, and Teensy family. These additional boards all have a software patch that is easily downloaded and installed. Indeed, my Beginning C for Microcontrollers book has instructions for each patch. Once a patch is installed, the IDE works the same for all CPU's. The only potential tricky point is making sure the non-standard libraries are supplied for your patch. So far, that's not been a problem.
Our VFO module could be used as a standalone module, but there are cheaper alternatives (QRP Labs, $33) because our board has other functions on it. We have designed our boards for possible substitutions. For example, our filter board can use our toroids/filters:
... or QRP Labs filter kits:
We've tried to make it flexible for the experimenter wherever possible.
Anyway, if you know C++, my code really shouldn't be a problem and the Teensy patch is the easiest of all of them to install.

uBTIX no signal or reception
Hi All,
I think i have messed up my uBTIX version 6 ;-(
Installed Nextion Display and KD8CEC Software ver 1.200. I can't hear anything och dont have any reception. I have tryed to do a calibration but I cant get the rig to receive anything.? I have tryed to import factory settings but it didnt help either.? Any help are appreciated;-)

Re: One of the coolest smart knobs I've seen.

Nice!? looks like more unobtainium though.
It looks like just the ticket.? But for those of us with more money than brains, I was hoping to find something more...well...turn-key.
I'm not a programmer.? But I love playing with radios.? And I hate playing with computers.? Necessary evils I guess.? Prefer poking my left eye with a sharp stubby pencil than learning to program a 32bit system.? The learning curve is a vertical slope for me.? I can paste stuff together, and hook-up stuff.? But without a detailed recipe to follow, it is an endless wheel spinning frustration.? It looks like the esp32C development board is needed.? Unobtainium...And adapting similar would be yet another vertical learning curve.
Sigh...

Bud,
the ubitx was designed as a ssb rig,as Farhan states on his website and videos. The CW, I use CW alot on mine after i changed the software. I uploaded the n8me software and it took care of the latency(delay between hitting the paddles or key and the seconds or so before it sounds.
The software also takes care of the tuning jumps with stock software. makes it very enjoyable. The ubitx is really ahead of itself in many ways.
Anyway ,Hope this helps,

Re: uBitx v3 finally assembled... now it just sends dits on power up?

Matt,
Glad to hear you found the problem.
Here is a link to a video by Ashhar Farhan on calibrating and setting the BFO.? It is for the v6 as the instructions are using the v6 controls.? The same basic steps work with the v3 and v4 with stock software.? It does not work with the v5 as the calibration process with that software puts the uBitx into transmit mode for calibration.? The stock software provided with the v5 was the only one to use the transmitter to set the master clock calibration.
The three main steps are:
1 - Set the BFO so that there is a maximum signal at the low-frequency audio levels to hear for the zero beats.? Using the Tuning Aid page means taking the plateau and positioning it to the far left in the window.
2 - Using a know AM signal (This can be a signal generator provided you trust the accuracy of the frequency generated), set the dial to the AM, put the radio in calibration mode, and then adjust for zero beating.
3 - The last step is to go back and adjust the BFO for the best audio for speech.? The BFO adjustment is centering the plateau in the center of the two red lines.
Have fun with the rig!
