I have XP Power Model AEB100PS48, 48vdc switching PSUs (resemble a
laptop PSU) that are pretty stinkin' quiet. Don't even HAVE to have
torroids on the input/output.
I loathe switchers, but I didn't want to buy a 48vdc analog supply just
to power one component (an old TELCO GPSDO that I am modding to work
outside the rack.)

My neighbor is throwing RFI out that affects 15 and 10m bands. We
finally traced the source to a Unifi US-8-60 internet switch that uses
a separate 48v power source. Naturally it's a dreaded switcher, so he
needs either a clean switching supply (if it exists!) or a analog
supply. I'm unable to find anything resembling a wall wart style.
Can anyone suggest a solution? These internet switches are showing up
much faster now and represent a big potential problem, compared to the
typical router operating at 5v with the 14.029 noise. Jim W6YA
