Bummer that is was not as claimed. Its not like doing it right is hard or costs much. Some examples here: https://m0ukd.com/homebrew/baluns-and-ununs/91-magnetic-longwire-balun-unun/

You first.? Do it right this time. Your methodology is faulty and the results are corrupt. I've already made that exact error before, you want to stick by it its? not something to be proud of.

Re: Anyone with a Raduino for the uBITX version3 for sale?
Hello Daniel I have pulled the blue and green wires from the plug and soldered the 4k7 resistor to the raduino board, and it still does the same thing. It does this when I don't have 12v to radio -

Hi Dan, I googled to see what other values are quoted for the pull-up. The input impedance is claimed to be 100 megohms. The pull-ups, when activated, are 20k ohms to 50k ohms according to the Arduino

Yep I wasn't independently thinking, but when Allison mentioned putting a resistor across the terminals like when used as a dummy load, I knew what she was talking about. With a 470 ohm resistor my

I just installed an LM380 amplifier instead. Why an old '380? Because they are rated for 22 volts and I had a bunch. Found one with less than 5ma. quiescent current. Very quiet and just the right

Allison i am not going to engage further in these semantic battles. I have produced data, discussion, and transparent methodologies. You have produced words. Your agenda does not seem to be in pursuit
