Thanks for the reply David – I thought of you when I posted. I am keen to get some replies from HF listeners where particular “brand”/circuit supplies get commented on.
Any idea how your watch [supply] performs [when displaying] around HF comms?

No problem. But seriously, it is possible to build a low-emission switching supply. It takes time and care and shielding. High voltage is more of a challenge.

I often suggest that they look at the various Nixie supplies discussed here. The usual response is along the lines that ANY “switching” or not-linear-regulator supply will cause too much “noise” on the radio bands involved. Are there any active ticketed amateur radio guys here who have had first-hand experience of this topic and are willing to share their wisdom?
