Dear All, GOOD DAY. I also have the same problem.Can we use the Mic available in the headsets of the mobile phones in stead of the existing MIC in Baofeng Microphone (supplied uBITX V6)

Dear All, Good Day. Can we use the microphone available in the head set of the mobile phones and disconnecting the existing mic in Baofeng (mic system supplied with UBITX V6) duly

My boards have worked continuously on 15V with no issues. The poweroutput increases, you only need to put a heat sink on Raduino 5V regulator as itgets uncomfortably hot. It may then drop voltage. If

How have you concluded that it is defective?

Hello Dave C, We have asked you in your post (IS IT POSSIBLE TO RETURN THE DEFECTIVE RADUINO THAT WAS SUPPLIED WITH MY V5 DAVE C GW0NVF https://groups.io/g/BITX20/topic/75067622#80043) to send us

I have one of these installed in my uBitx case. Works great. https://www.amazon.com/dp/B00MF70BPU/ref=emc_b_5_t -- Mike WA0YCN

I finally got the case and antenna adapter for my V6 and figured out how to do the calibration (from the video). But I had the same issue, problems with getting to the set-up menu. Once I did get to

Could indeed be a defect in both the Biennio BMS and in the uBitx, as you suspect. Very weird that the uBitx works (for awhile) with the Biennio, but not with a bench 12v supply. You could be right

Hi Jerry et al The other sources I’ve tried are plenty beefy—the 30A supply I use for my home station (incl Kenwood TS-590s) and some 30Ah AGMs with full charges. Current draw isn’t our culprit.

Tim, Hmmm, radio only powers up when tied to a big battery capable of supplying several amps, not when powered from a wimpy 1 or 2 amp 12v supply? Check current consumption into the uBitx when

Hi Tim, It is a simple procedure to measure the output of the regulator and see whether it is nominal or not. A 7805CV is rated as max input (from memory) of around 25V. Let us know what you

Another mystery! I power my uBitx v5 with a LiFePo 3.5Ah battery from Bioenno. It's a new battery but a little while back, the radio stopped powering up. Long story short, the battery was found to

Are you putting batteries in that power mic? -- Mark, kb9woo Milwaukee, WI uBITX v6

the firmware version is correct. I can think that it is mostly related to a missing calibration. I overwrite the firmware directly on the original nano but as you wrote this shouldn't affect the

You're right, Gordon. Thank you.

Rob: I don't know what happened to them. Jack, W8TEE

Mahendra, These are the batteries I was referring to... by

Hi Dean, I don't homebrew batteries. That would involve handling more hazardous materials than I would be comfortable. I homebrew the maintenance and charging gear. My approach is not entirely unique

Could you give a bit more detail on the batteries and a link if possible? I was looking for a lightweight reasonably priced battery and to use a solar panel to charge them on my trips to the

Please review the following video before you do the calibration. As is stated in this thread, it is very easy to get it wrong, and then can be difficult to get it back to working. Since you have
