On my SECOND sBitx (which I bought used, once again) here are the items I plan to do (I prefer the V2 model, just because it offers me a bit more "headroom" for digital etc on the lower bands -- I

Thanks Ashhar, so there is no solution if sBix DE is used? Ramón

This radio is ground-breaking in that it is NOT a $1200 Icom and Yaesu and yet it has many of their features, and sometimes does things far more expensive radios cannot. Instead of using $15 final

Hi Gyula, I remember reading about a failed DE output transformer. The stacked toroids cracked due to heat, leading to the V2 and V3

Bravo Delta, I've read almost every message since the summer of 2022, but I don't remember a melted transformer. Could you give me a link to what I missed. If you read my post today about v2, then I

Delighted that you found the problem. Interesting that both drains showed an AC voltage even though one device was effectively shorted. That is surprising to me. Wish you the best Gordon kx4z

Wojtek, Buy 10 pieces so that you can choose the two with almost the same opening voltage. They may be the same in shipping, but there is still a difference between them. You can install them without

I would wait on the insulators myself... They help tremendously to be honest. David - WK4DS

Thanks JJ, the output to "aplay -l" is: pi@sbitx:~/sbitx $ aplay -l **** List of PLAYBACK Hardware Devices **** card 0: vc4hdmi0 [vc4-hdmi-0], device 0: MAI PCM i2s-hifi-0 [MAI PCM

Couple of questions: Is it because people are experimenting more with sBITX that we are seeing more failures? Does it have automatic output reduction in case of High SWR as in case of regular

Hi there, I've been seeing posts about burnt finals, melted transformers, etc. Is there a way to "invest" into parts for the sBitx V3 to make it more resilient. I would not mind to buy beefier

I have finally disassembled my sBitx fully and removed final MOSFETs.? I have to cut the away to not damage the PCB. One of the was still alive (so I'll probably use it for prototyping): But the

No documentation was sent about any changes to the v2. What happened was that the devices sent in April 2023 did not come with any information sheet, so on May 3rd, several messages came, which can be

Hello Evan, I tried that yesterday, and found that the resistance remains below 1 k. Another fact was that the DC voltage on gates with power, at minimal drive and PTT on didn't change as

Wojtek, I suggest verifying that adjusting the PABias1 pot does change the voltage on the MOSFETs' gates.? As Gordon stated, you need to be careful when making this adjustment.? It is very easy to

The strange thing is that performing the bias regulation (as described on the website) I couldn't get the increase by 200 mA in the whole range of regulation. May the transistors be partially
