<DIV><FONT color=#0000ff size=2 face=Arial><SPAN class=568443916-26092009>When
using my pandora boxed hpsdr/picopsu in my URBAN environment I cannot trace any
noise contributions attributable to the picopsu. If I had a rural location with
low noise antennas/low noise environment it might be another
story!</SPAN></FONT></DIV>

havent done any mods to the picopsu, apart from cutting off ALL the extra

<DIV><FONT color=#0000ff size=2 face=Arial><SPAN class=719351913-26092009>Yes,
the PicoPSU was discussed here on this forum before.</SPAN></FONT></DIV>
<DIV><FONT color=#0000ff size=2 face=Arial><SPAN class=719351913-26092009>I
think Phil VK6APH tested it for noise and I think he reported some
issues regarding noise/interference with it when used as power supply for
HPSDR, but good to hear it works for you.</SPAN></FONT></DIV>
<DIV><FONT color=#0000ff size=2 face=Arial><SPAN class=719351913-26092009>Did
you do something special/extra to get away from the noise
issue?</SPAN></FONT></DIV>

havent used that one but I have used the picopsu-120-wi-25 from <A
href="http://www.mini-box.com">www.mini-box.com</A> to run my hpsdr
portable for the last 6 months without incident or noise issues. I also
use one to run my D945gclf2 motherboard. I would get a more of them
(one to run my other D945gclf2 motherboard) but they have been out of stock
at that web site for the last 3 months!</FONT></SPAN></DIV>
