Tony, I know this sounds stupid, but have you checked the connector on the sbitx? might have been loose or came loose when tightening and broke the center conductor? good luck on the repair. Maybe use

The *LICW Refrigerator Magnet* is printed on flat magnetic material, the very same magnetic sheet stock that is used for all those useful calendar magnets sent by your favorite insurance companies.

Perhaps I've missed it, but in the past discussions about sBitx clocks being off, I don't recall seeing this issue: the time displayed in the sBitx app title bar is approximately 5-6 seconds behind

If you can get anything to work, use it. I don't think anything does, but that's me

Barry, The voltage is between 5.25 and 5.4 volts.? 5.27 is good. 73 Evan AC9TU

Group, what is the target voltage for the little buck regulator for the 5v bus? Mine is set for 5.27V. I THOUGHT I read someplace, which I cannot find again. the voltage should be 5.6V?? TU Barry K3BO

Thanks for the update de vu2upx

Hi All, I'm running uBITX_6_N8ME_Cosmetic_Mods.hex firmware on my uBitx V6, I love the looks of it and the fact that I can store some memories however, the calibration setup is just totally broken. If

OK, I resolved this. ?Traced it to the default screen resolution as set in the raspi-config being something other than default. Changed it to default and touch is now calibrated. I don't think I ever

Hi all - Continuing to progress with the homebrew SBITX -? I tuned up the final so I am getting about 5 watts out clean.? I had the bias too low for the RD06 that I am using for the final PA.? It

I built the audio anp directly from the schematic. It looked to me like RD21 at 10k was all that was needed.? What else do I need?

Gyula, Thanks. To clarify your comment, are you referring to the reported min/max being the default when running input_calibrator and not picking up what is in the 99-calibration.conf file? I tried

Have you added the bias resistor needed for the electret mic to operate?

Hi Rafael, Curious about the ALSA mixer settings for the mic. For my home brew build, I built the mic amp from the SBITX schematic. I tack soldered in a electret capsule of unknown spec that I just

No dude, it’s you. You suck and it’s not going to work. Go back to the icon you already have and remember, “computers and radio have never worked for you and never will. Save the frustration and

Cool. Lets us know! Remember that if you are using Farhan's sbitx reference implementation, edit the mixer code to use the line instead of the mic input. Or just play with alsamixer (and any audio

Mark, I mean the selected area is bigger than what was produced on the screen. try to select a smaller area. -- Gyula HA3HZ

Charudatt, You solved the smaller size, I think single-lane version, skillfully. Since I have some parts that are needed here, I would like to build it. If you have a spare set of pcbs, I would buy

Hello, Good to know that this is not your usual radio. This is an RPi controlled sdr radio, the soul of which is Raspverry pi 4B. It should be noted that it uses Raspbian 10, i.e. Buster OS, which

Thank you for appreciating the design. This board was drafted in KiCAD software. This is made using 1/8W TH resistors and capacitors. This is only the exciter board and I share a PIC in comparison
