Re: zBitx power draw
At 9v and 100% I was showing 5 watts out with a current draw of around 3.8 amps on FT-8. Cheers Jim

It wouldn't be a 1:1 swap. The GPIO pins are in a different configuration on the Radxa. It might be possible to change all the pin assignments in the software to get it to work.

Re: New zBitx - New User - CW operation
I finally got on the air(portable) yesterday to do some FT8 running Drive@100 for about 45min on 20M and didn't overheat (the back was warm, but nowhere close to hot). The swr was 1:1 into a 17ft

There are so many things to improve in the firmware, at least I still resist asking for a unit! I'll wait until things become usable. It's not a complaint¡ªI admire the work of the developers. I know

Re: zbitx - questionable SW/HW
Fascinating! The CW area seems to be the one with the issues so far, so many may not need this. But an interesting upgrade option! Good portions of the problem have already been solved by software, so
