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

Ther is a factory reset feature on the KD8CEC (referred to as CEC) firmware.? I do not know if there is one on the firmware from HFSignals.? I very quickly replaced the stock firmware with the

Coverting bitx3b for example, should not be difficult. They use lc bfo and crystal bfo. Whrete they used dds vfo, it is easier. Now let us comebto the front end bpf. Itvhas to be re-designed for the

As K7UL mentioned, you'll want to actually open the .ino project. It looks like you opened the IDE, but didn't load the actual code. For the "processor" in the menu, try selecting "ATmega328P (Old

Ouch! Sounds like some of the smart people also have thin skins. Please don't insult them by asking THEM to learn anything more than they already know. It seems some of them demand to be spoon-fed

If you have the right firmware I think you can reset to factory defaults first. I’ll let Evan call it because he is more familiar. Joe KD2NFC

Idk. I might have an older copy allaying around Joe KD2NFC

I did more searching today.? It seems that people have done this conversion, but again, NO DATA AVAILABLE (such as the proper cans for filtering and so on).? My main radio is unreliable transmitting
