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 _._

Allard's code is a very good starting place if you wish to create your own version of firmware for the Easy Bitx. But I have absolutely no idea what you are doing. From this, it sounds like you may

All, The uBITXv6 is with the TSW Raduino is a very pleasant machine to listen on...but when I transmit, nobody hears me. Or if they do, they don't answer. Constant rejection! Almost like working in

Jerry! I have the stock firmware sent by sunil which with wish the board was flashed ! VFO and BFO issues are arising in the stock firmware supplied by sunil The one by? Allard Munters PE1NWL is

That is **NOT** stock firmware for an Easy Bitx. Jerry
