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

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

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

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

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

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

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

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

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

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 Like, theory of operation. Initial assembly Calibration

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

That file worked well for me. It is a .hexx file that needs to be uploaded with Xloader. 73's Mike WA3O

May have to RIGHT CLICK , save as A hex file is a list of ASCII with Addresses <oberman.l@...> wrote:

Same again unfortunately Laurence. Perhaps send it to my email address? m0clscarl@... Thanks for your help.? Regards carl.

Carl Try This

Thanks for the file but it won’t download? When I click it it’s just numbers in the browser. Unless i’m missing something....

Steve- ? Thank you for posting your clubs findings. I commend their efforts. This is the most detailed comprehensive explanation I have read on how to calibrate. Maybe this weekend I will retrieve

Carl I had built this for Mike already, here it is

I to would like to help..? I am close to ordering a uBITX v5 and was considering trying to document the build from the perspective of the uninitiated.. ? I am a new ham with some experience in

Hi, I have built the nano I2C Signal meter from hamskey but I can't find the HEX file to upload to the second nano anywhere?? Can someone point me in the right direction please? Regards Carl M0CLS
