Hello everyone! I would like to share with you some informations, I installed a new Inverted V antenna for 20m and I discovered that my uBitx is transmitting some "shadow" signal along the center freq

Thanks a lot, Ted!

Hello everyone! I am currently playing a little with my Ubitx and I have an issue which bothers we since the beginning. The microphone gain is not pleasing me. I literally have to scream into it for h

Thanks everyone for the assistance, I will try to put in practice the advices you all gave me. First of all I would like to try Dr. Ian's firmware, I just give it a try to see if the problem persists.

Hi, and thanks for the informations. I would like to say that my antenna is an attic dipole for 40m and I use 50 ohms coax. What I didn't said in the beginning is that I disconnected the display and I

Hello everyone! I have a case from an old 2m transceiver and I decided to use it for my uBitx. Everything is fitting well, I am proud of what I accomplished. I have a big, BIG problem. Whenever I push

Hi! As Mr. Jack Purdum stated in an earlier post, to work properly, the Arduino IDE wants your sketch to reside in a directory with the same name as your sketch, in our case "ubitx_20" because our mai

Thanks a lot for the informations about setting the PA bias. That helps a lot since all the informations about setting the bias are taking in consideration measuring the current drawn by the whole boa

Hello everyone! It has been a while since I got my uBitx, I tried so hard to find some kind of an enclosure because working with the board itself it's kind of hard life for me. Wires all around... So,

Okay, that's gold! Thanks for the information!

But let's assume that when you press the CW keyer on uBitx you send a signal of 700 Hz . If you press the PTT button and inject a sound signal of 700 Hz through the microphone wires, the transceiver i

The computer decodes what it hears from uBitx speaker :)

Okay! Now I think I understand. I connected uBitx to the computer on USB and I have control of the PTT and frequency change. Also I put the speaker of the Ubitx close to the computer's microphone (no
