I am also suggestive of the fact kit is not bad! the firmware is poor! Quality of PCB is outstanding for that matter! Also, the firmware copy supplied on email when flashed writes Earnest on the radio

I can provide you with the 'STOCK' Firmware for dissection that has been mailed to me by Sunil. I am unsure, why he is not posting it online. I wont be posting it here any way or uploading it anywhere

Sunil, Your file VFO_BFO_DDS.ino? uses the Si5351 library from etherkit. Here are the many different releases of the etherkit Si5351 library: https://github.com/etherkit/Si5351Arduino/releases Since

I've done it a different way using a PIC, but no reason it couldn't be adapted to any other micro controller like an Arduino https://www.vk5tm.com/homebrew/freq_switch/freq_switch.php (

Sunil, I'm convinced you have a solid product that works well. It fills a need, as HFSignals no longer sells a single band rig. Experimentation is encouraged, and I rather enjoy trying to figure out

In case anyone is curious about this business of the BFO moving when the VFO is changed: If it is a library issue causing the Si5351 to tune a common vco that is used for both for VFO and BFO, then

Bill There are no unworthy questions, each of us should admit to learning something here. Team Would not it be logical to host bitxmap at HFsignals?? One could invite buyers to add themselves to the

Jerry we provide a working DDS unit using si5351 which is tested with Freq counter . Now If any one has doubt on the DDS he is supposed to check the Freq output of vfo and bfo . Out here the builder

Hi, I would make sure you board is well grounded.? The cases are often painted very well so the standoffs and screws never make electrical contact.? Clean off the paint in the inside where the

Sunil's firmware as programmed into the Nano he ships with each radio is fine. He has sold plenty of them, and they work. I still don't know what you have done, or what you are doing. On scant

Bill KB3YV From what you posted, your uBITX is a V-5. There are not a lot of differences between V-3, V-4, V-5, and V-6. Most of the factory changes were focused on FCC compliance. There are several

and #define BFOFREQ (9997469UL)????? // initial (uncalibrated) BFO frequency (Hz)

I didn't realize there were so many different models. I have no idea what model it is but when I turn it on it says uBITX v5.1 I joined the group to learn more about it before asking stupid questions.

so i changed ????? bfo_freq = constrain(BFOFREQ + knob + shift, 9997469UL, 12000000UL); in? Allards code and in the settings menu, i could tune the BFO... Kickass sinusoidal repsponse. Now

Hi Bill, What's your trouble with the radio?? What model/version is it?? There should be enough people here to help you get it going. 73,? Mark

Any time to sign up is good. Go for it!!! Dave WD8AJQ Sent from my iPhone 5

I just finished assembling a BITX I bought maybe a year ago. It doesn't really work yet but I am trying. Should I put my location on the map? bill KB3YV

David I will look into it. Of course it has to be cleared with Farhan before I make the change. Arv _._
