Default C. Crane's Twin Ferrite Antenna

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.
