A few months ago, I posted here asking about a problem I was having with
noise on my hf radio coming from my computer.
I had narrowed it down to the power supply ( by disconnecting everything
from the computer case and turning on the power, only to have the noise
at the same level ) and I finally replaced the offending power supply.
I replaced it with a ATXPOW450PRO from StarTech.com. It is a 450 watt
supply, with 8 hard Lp4 drive power taps, 3 floppy SP4 taps, a single
mother board connector, 1 x 4 pin extended ATX 12v for pentium 4, and 1
x ^6 pin auxiliary plug so it should run just about anything that run an
ATX supply. It weighs in at 4.6 lbs. pretty hefty!
Now for the rfi ( or total lack of ) report. No news is good news in
this instance. I can see no difference with my computer on or off now.
Happy days! I am back on 75 meters with hf and internet at the same
time. Of course, the wife will not like me being back in the sack as
much as before, but hey, she is supposed to understand. ( She's a ham as
well. )
Not often do I get to report complete success in my quest for reducing
noise on HF. I happy to say I am totally please with this power supply
and it may be worth a try for anyone having the same problem I had.
