I recently rebuilt a computer for use in my ham shack, and
set out intentionally to replace the hard disk and power supply
(which both had to be replaced anyway) with new units that were as
quiet as I could possibly find. The results were astonishing.
You have to get within a foot of the case to tell that the computer
is making any noise at all, and the noise that it is making is almost
entirely that of the fan on the CPU.
This has gotten me to thinking, and I might be able to write
an article for one of the ham publications about this, about how
one could reduce noise in other common components of a ham radio
station. Yes - most contesters and DXers probably use headphones
for serious operating and probably don't really give much
consideration to the audio noise pollution in their shacks.
But for those times when I'm not wearing headphones, I know that
I personally would prefer a quiet environment. I'm even willing to
spend a little extra to make it that way.
I'd be interested in hearing from people about (a) what was
just too loud and bothered you enough to replace or modify it to
make it quieter, (b) if anyone has good pointers on how to
spec replacement fans that are quieter but still move enough
air, or (c) any other ideas on how to reduce noise pollution inside
a ham radio station.
