Hello Glen, IIRC it's only the LM386 audio amp that runs from 12V, everything else 3V3. We put in a fair bit of effort to make it run from 12V (switcher etc) because that's what's usually around in a HF station.
The SM1000 page has more on the PS specs. - David On 10/01/16 09:59, glen english wrote: > I reckon that is pretty good.
