Have you measured the voltage at the electret element itself? tim ab0wr t.h.mills@... wrote:

I disagree that the original software is a good starting point for building on as its tuning and keying section need work. I think the uBitx should be shipped with a software that best promotes it's

Tom, measure the voltage on the slider of the tuning pot with a DVM. It should range from zero to +5V depending on the pot position. Also make sure that the tuning pot is wired correctly. The purple

Lead length at this frequency is mostly irrelevant. Stray Capacitance could be an issue in side circuit coupling or if the circuit is oddly designed at an extremely low capacitance level. Stray RF and

I've had several people ask me about this since I mentioned it several days ago. To find your compiled hex file: 1. Go to your Preferences settings (File --> Preferences) and check "Set verbose output

I am not yet using KD8CEC's firmware on my uBitx. Does this firmware support the "factory-sent" feature of increasing the tuning step as the tuning knob is turned faster? If not, I won't be upgrading,

The lead lengths on my components are not any longer than SMD components. I'm using 1/8W resistors, miniature caps, all mounted horizontally, flush against board.?The 2N3904's are all mounted?flush

So, I just got my uBitx and have it all wired up.? It receives fine.? But, there is no transmit audio.? Here's some interesting information.? I live about 1 Km from an AM radio station putting out

Please add 1 of each board.? Thx Gary K3OS

Hi Jack, I'm not a programmer any more and would certainly like to learn how to "find the hex file", "generate the hex file" and "learn a little bit about programming for a Nano in the Arduino IDE".

i have put together my bitx-40. When I turned it on, the display came on and just said "Raduino v1.01" . The frequency control doesn't change anything.? Am I missing something here?? Been looking

My Siemens BB112s came out of my collection of things at least 20 years old. ONSemi probably has got a VVC with a 400PF + rating.
