[hpsdr] PICOPSU-150-XT

[Doug Bade]

Kjell;

         I am using a different product from the same vendor called 
an M2- ATX. I power both the Intel 945GCLF2 Atom 330 and the Atlas 
for Mercury Ozy and Pennelope... I does create some small amount of 
RF noise but not bad.. Proximity to the device draws it out as it is 
induced as opposed to conducted... Since proximity is an issue, the 
direct plug in of the device you are asking about would theoretically 
tend to make it worse.
         The M2 is a separate board. I mounted it 6 inches from atlas 
and see no significant noise to speak of.. a couple db... maybe 
bother the purists but for around here, the atmosphere is worse...

         <http://www.mini-box.com/M2-ATX-160w-Intelligent-Automotive-DC-DC-Power-Supply>

         I made a plug from the 12v and 5v of the already cabled and 
available drive connector to run atlas/merc/ozzy/penny.

         I plug the M2-ATX directly to the motherboard. The whole 
thing runs off 6-24v dc.. which I really like.. Power supply source 
regulation ( IE Field Day) is now a non issue.. Just need a monitor 
now that runs off 12v unregulated :-)

         The M2-ATX also handles ignition sequenced shutdown of the 
motherboard etc... I highly recommend you look into it... if the few 
dollars more are not an issue...
