Did this go away? I haven't been able to reach it lately.

Hello,

The recent Haystack work party managed to install a receive-only SDR up
there.  It is provisionally available for use by anyone at:

http://44.24.241.60:8073

I'll move it to a more permanent address, with proper DNS, at some
future point.

In the meantime, I'd like to solicit advice on how to minimize the QRM
it's picking up.  The noise is being emitted by the site itself, from
the Ethernet cables and such.  I've connected all the shields to site
ground, but the emissions are still there.  The current antenna is a
ground rod with vertical whip.

1) Is there a better antenna design that can serve the broadband
(DC-30MHz) omnidirectional receive duties?
2) Are there any suggestions on how to further minimize the noise being
emitted by the site?

Thanks, and enjoy!
