I bought this antenna on a 30 day trial, and just got it about 12
hours ago. So far I'm not at all impressed. I live about 150 miles
from an AM station, at 810, in the SF/SJ Bay Area, which has a
marginal signal, but usually listenable. Putting a new PSU in a PC
about a month ago increased the noise in AM radios 70-100' from the
PC to an almost unacceptable level. I had hoped the antenna would
boost the signal enough to knock down the noise. There are times
when I can get a good signal from the station, but certainly less
frequently than before.




Any rf noise put out by the computer ps is going to be picked up
by your antenna as well as the radio station you are trying to hear.
So a better antenna (if your new one is indeed better) wil just pick
up stronger power supply noise. It's moslty a null situation.

What you need to do is get that power supply fixed or replaced

I think the only solutions to the PSU problem is to buy a much better
one. As I mention above, that's probably a losing proposition. I doubt
after 6 weeks they would take it back. It might be worth a try though.
Note my comment above to someone a few moments ago that this seems to
be a household circuit dependent problem. Another PC in the same room
works fine until I plug it into the socket that I first noticed the
problem.



Hmmm, just maybe, you might be able to ditch it as a warranty item.
Dunno tho' as it will depend on the outfit that sold it to you. I don't
know if you are a Ham or not, but if you are, you might play the part 15
card, as they are required to not interfere. I suspect that a 160 meter
rig might catch the same interference.

It is kind of a drag though, since IIRC a noisy switcher Power
supply is hard to fix. Good luck!

I'm tempted, but somehow your message gave me another idea. I think I'm
going to take the PC to an entirely different location miles from here and
see if get the same problem.
