Hi Dries, It looks like you have been working hard on this.? Good job to get this far!? It is much harder to work from scratch, than to build a kit, but you can learn a lot! This site:

The short answer is yes, if you add the screen features you want to the Arduino firmware.? I am not aware of any such firmware available.? There is also a shortage of I/O in the stock Raduino. I

Dries, Here's what I hope is a helpful answer to your questions about the Bitx20 Yes, you could use FT-37-43 cores on the transformers. Just duplicate the transformers used on the Bitx40, 10 turns

Brad, In the past every time that issue has been seen it was the 40 low pass filter having wrong components installed at assembly.? Other wise the issue would be evident on other bands. Generally the

Dries, I remember you mentioning that you had changed things around. The one you posted is exactly the original. Can you post your own version' diagram? Second, what kind of equipment do you have to

OM hard to quickly resolve how many issues remain with your build.? on receive - I wonder if BFO is properly adjusted.? note this oscillator must be appropriately adjusted to mix the RF into the

Senior OM fine news on your successful build.? I think you refer to a larger LCD display?? there are 2 custom versions of uBITX software but I think they only work with color displays - others can

I am han radio from cuba. I build the Ubitx and working fine. The questions is I can use GLCD 32160 to put un my Ubitx

Ham since '07, building a Bitx20 in '12? OK, have you built simpler in between? That should have taught you the basics of troubleshooting and given you some basic test-gear. A Bitx2o from scratch is

CODEC2 looks interesting. It seems to be a breath new life for older research and makes it work well thanks to modern DSP technology. The original researchers could not get past a certain technology

Hi, I have the ubitx V5 board, and have reduced power on 40 meters. All other bands/frequency ranges? are fine. I am getting 10 or more watts out everywhere but 40 has about 6 watts. At tp7 before

Ah, I see that Farhan responded, you're in good hands. The only problem I see is that he will tell you how easy it is. Which for him, it is, as he has debugged plenty of these radios. He might even

the diagram

That's a very long list of trouble. And? a rather old Bitx design. Most folks in this forum are now using either the Bitx40 or the uBitx from hfsignals.com. Radio circuits are seldom simple to get

Knowing that I might open a can of worms, here I go: I have been monitoring this group for almost a year now, and have not seen any information posted on the original BITX20 during that time.? I also

Can you post a circuit diagram of your effort? Possibly with a picture of your build too? What kind of test gear do you have access to?
