Default AM Antenna Problem

I have Sony stereo recever in my office. FM reception is ok, but I get zero AM. I have experimented with AM loops (the plastic loops that typically come with receivers, of which I have several sizes from receivers I have owned in the past): reception of the one station I am targetting improves a bit with a loop flat against the window glass, but not enough so to make it listenable. I tried the Terk Tower amplified AM/FM antenna - that was worse than the loops - no signal at all.

Any antennae you would recommend for this purpose? Anything I could home-brew that would be better? I am targetting 640 khz?

If the building - note that this is a Fortune 500 corporation - was designed to keep 802.11bg signals in (wireless networking) - could this be part of the problem? how can I overcome it (without breachingthe integrity of the walls).

Thanks,

J

You'd probably need an outside antenna of some kind. This station
doesn't stream on the web?

The station does stream, but streaing is blocked by the firewall at
work.

It is hard to believe that there are no alternatives - I hear the
station (faintly) when the loop is placed (and oriented properly) on
the window sill.

Is there a website dedicated to passive AM antenna design out there?
The other experiment I have not tried i connecting the ground terminal
lug of the recever to the electrical ground of the building, while
keeping the loop tied to the othe lug. Will try that next.

Check out the new Sony gadget at, www.smarthome.com/6346.html
With that new Sony gadget,you can access your computer from your home
and online radio and tv stations too anwhere in the World,or so the
advertisement at www.smarthome.com claims.They sell a 7 inch screen
model for $899.99 and a 12 inch screen model for $1299.99.I want me one!
I think they require broad band internet access.

I can pick up 640 kHz on my radios.I don't know what kind of a station
it is though.I hear some Spanish music but it comes in faint.The station
is either Northwest (Colorado,perhaps?) or Southeast of me.

I'm 45 miles from KFI, more or less, too. Since their tower fell down
they've been on half power through a little 150' or so stick. Why is
hearing Limbaugh and Doctor Laura so important?
