A little more detail: The receiver functions but audio is highly distorted and sensitivity is poor. It seems like the filters are not properly centered. I think I messed up a prior calibration

Hi, I purchased my v4 in December 2018. The receiver initially seemed to work correctly but no longer does. I suspect I messed up a calibration or inadvertently caused some code-related issue. What I

Hello, Haven't been here in a while... But I need help trying to compile the Original 6.1 Code and the updated 6.3.1 Update. I have downloaded both and installed correctly in Arduino 1.8.12 but when I

Alrighty... I finally got around to a couple of things: (1) Building myself a "digital dummy load" using my QRP Labs 20W dummy load and an Arduino.? I calibrated it against my ATU's wattmeter, which

The ten cent element is the electret element that came with my V5 kit.? Out of curiosity I looked at an online parts place (probably Digikey) to see what they cost. Looks like 9-10 cents each in some

Sorry to be so slow! I just opened up the mic head and removed the contents, unsoldering the old element. I cut a new piece of foam out of foam sheet I had around to fit inside the mic head and also

How much would it cost? I understand it aims to be a low cost device. But how much low?

I wish to pass this effort in England along to those who are on the "Ventilator Project" for perhaps inspiration. I note that they are using arduinos as the controller as well, but are using an ambu

If you just want to try it out, bypass the bandpass filter and change the vfo to get the frequency coverage desired. take a look at this. http://golddredgervideo.com/kc0wox/bitxsmd/smdbitx.htm The web

Still "tuned in " Chris. One step at a time :-)

Anytime I try to put a condenser element into any other microphone, I'll find some soft foam padding in a sheet or in a block that I can cut into a neat piece to fill the inside the subject microphone

It's the Version 3b with vfo.? I've got most of the parts for the Digital VFO unit for it as well, but missed some (I purchased the kit unfinished at a hamfest and put it together - discovered parts

Robert sorry to see that negative post except I kind of saw it coming. Anyway the architecture of the BITX20 and the uBITX are very similar so replacing the filter elements for 20 meters with the 10

Glad that we could help. Do not feel alone, all of us have done this sort of thing.? That is where having another person review helps catch the simple mistakes that so often get us. For me, hunting

Hi Evan When you asked about the code, I did have KD8CEC code on it. I put it on because the stock code was not working. So I went to install the stock code and saw at the bottom that there was a pdf
