Re: What is the actual status of the sBitx V2
Dave, I’ve probably had more experience changing finals and working with their heat sinks both for the DE and theV2 than most out here. I don’t think that most blown finals are because of heat

Dave,
Feel free to use a larger SD card for continuous use. Currently, 9GB of the 32GB or 64GB is used.

Re: What is the actual status of the sBitx V2
I would say that yes, you should strongly consider a different mechanism for securing the PA transistors to the heat sink.? You mentioned elsewhere that you have had 20-25 failures out of 500

Please excuse me if this is a dumb question ... I'm a total noob when it comes to the RPi.? But is there a reason why simply using a 64 GB card isn't advisable?? The cost differential is

LoopMasta,
The voltages you listed do not make sense.? A zero volt on the Drain of Q28 and 12 volts on the diodes would mean that L27 is open.? Can you verify that there is continuity across

Re: Smoother tuning on the uBitx v6 (or other radios with plastic knobs)
Using Felt thats not thick enough, just double or triple up layers. TenTec did that for the Corsair and possibly other radios.

Re: sbitx v2 dial lock
Hi All,
I’d vote for a short press of the tuning encoder to execute tuning lock leaving the long press for something else.
A dial lock indicator would be nice.

Re: What is the actual status of the sBitx V2
It is a bond that cannot be disassembled under the influence of heat.
The thread is a releasable joint, another thing.
And it is precisely the female thread that must be fixed so that it does not

SD card burning with latest software build
#sbitx_v2
Hi,
when I unzipped the latest soft for V2 I realized that there is no extension in the file name.
I expected .img or .iso file.
Is it ok to just rename it with .img to be burned correctly on SD card
