We have added some 3d printed mini mic housing and paddles.

All hardware is included (Mic's use the stock element and tac button that came with your bitx40 or ubitx) you need only solder or glue for magnets on the paddles

We have Red and Black right now and Grey coming soon! If you would like a color and don't see it drop us a mail: info at kit-projects dot com

Agc's are still in stock over 100 sold!

HI Everyone.
I'm working on a nice little add-on board for the uBitx.
It contains:
- 200hz CW Filter
- Mic Preamp (SMM2167 Module)
- VK3YE LED AGC
- LPF section (Dual relay per filter)
I will try do it all TH, but the 100uh inductors underneath will need to be 1206 SMT...

Maybe $5 a board + post (VK-$1, DX-$3)

Here is a prototype picture:

Thanks guys! I'll give it a whirl when I get some more time.??Will see if I can use my tablet.

Trying to fix a problem I pluged the Radunio ?? board into main board ? reversed? and it smoked
I can't seem to find a replacement.

Thanks

V4 board, Noticed at uncertain times I heard my auto-tuner going in to a crazy auto tune mode and after a bit it would settle down by the time I got from the living room to the rig. It would only do it once or so in a 5 -6 hour time frame. Then now much more often. Suspect was the auto tuner so today after watching it closely while transmitting on 7.074 it would do its thing but each time I notice the freq. monitor on the tuner was fluctuating around 10.?? mhz. Still suspecting the tuner I swapped out to the manual tuner. Tuned and started to do some ft8, but just as before something would stick the ptt line and the meter on the tuner was pegged both ways... ie off freq. (prob. the 10.00 mhz) thing. I noticed I can stop the runaway by doing mike key or cw key causing the relay to cycle and it would resume normal for a shorter and shorter time till it went crazy again. This seem to say it is not the tuner but something going on with the rig. Please all help, suggestions or directions to where to look or do would be appreciated.

well, I tried the BFO at 55.5, tapped around everything on the board pressing down on the leads as best I could. Still no joy. Next I am going to start looking at all the solder joints to see if I come up with something there.?

Yes, would be handy if there was a known good starting point for the BFO.

Thanks for the help, Gary

The best way that I have found to adjust the BFO is to use a free PC based audio spectrum analyzer.? Connect a mic to the audio in on the computer, tune the uBitx to a clear frequency with white noise, and then adjust the BFO to center the signal plot between 500 and 3000 hertz.? This gives the maximum signal and best sounding audio.

Here is the link to the free software:


Note: after adjusting the BFO you may need to go back and recalibrate the dial.? When I did the BFO adjustment on my new v5 board, I had to go back and adjust the calibration for the dial frequency setting.

Above worked for me, YMMV

The next thing that comes to mind is BFO alignment.? Note that the crystal filter has a limited span, and the BFO must be set to that when the output is mixed the received signal is properly mixed down to audio.? This is much easier to do than the frequency calibration procedure, but actually it is more important to function.?

I have found a wiring error with the amateurradiokits. Its to do with the volume control pot, the black wire must go to the wiper and the brown wire to end hot end. this is more important if you use this to connect to an s-meter.

I worked on consumer and industrial electronic gear for over 30 years. I have seen unsoldered component leads in TVs, high dollar stereos and commercial equipment. Somehow, the joint didn't get any solder. Somehow, the simple physically-touching connection remained good through board testing, board installation, shipping and end-use installation. Then it worked for a while, sometimes years!

Some years back, Kenwood made a 2m mobile that was notorious for the LCD display loosing contact with the circuit board, resulting in a blank display. NASA had a Mars rover mission fail. When it comes to electronics, *stuff* happens, no matter the price, construction quality, or level of support.

Thanks Curt for help. Did some digging around and found cold solder connection (my fault) and fixed that. Now rig is working again but receive is still deft as a post.? WWV is s-9 here but can't hear minute announcements.? If I tune to each side of carrier I can hear that but nothing else. Tried to listen to ssb and can't hear them at all.?Seem to have good audio strength when rig fed with signal generator.? Anyone with any ideas on how to hear well?? Am using ear buds and a Icom mobile speaker.?

When wiring the nano the standard way (not routing the yellow wire from the nextion) do I still need to switch on the signal meter in dsp1? I’m not infront of the radio until tomorrow so can’t test it just yet.?

73s?

Finally got around to putting my uBITX 4 together. I seem to not have received an encoder. Is this a common type? I have few laying around. But I don't know much about encoders in general. Any Advice?

So one way to handle this is you have a chief editor, and have different people write different chapters on the areas they want to speak about

I am thinking we are coming at the matter of 'unclear instruction' from many angles.? The instructions provided by HFSignals do address wiring up the uBITX.? Much of the confusion described by builders relates to installation into a particular kind of case.? While I confess to having had my own issues, the data is around to address each of them in assembly.? Since the product is 'intended' to be installed or applied in different ways, its not possible to provide clarity in them all.? Some folk may have been expecting behavior like a commercial rig or ease of assembly like XYZ kit - but neither is intended by the venture.?

There are some fine assembly videos now on line.? The community has contributed greatly on lots of fronts.? I am thrilled to be part of the community as we continue to advance this rig.?

That file worked well for me. It is a .hexx file that needs to be uploaded with Xloader.
