[hpsdr] SW-mode PSU / Analog-PSU

[Bent Andersen]

Hi all

I have a angelia board and I use a Pico-psu at the board.... but when I use
a SW-mode as main supply I get a lot of spurius on 3.5mhz but if I use a
analog-psu there is no noise... and I have try 3 other main SW-mode psu
whit same result.

so now I am looking aftere a designe to build insted of the Pico-psu......
anyone build one whit good result ????
