Oh, it was hacked, I think via one of the hacked modems. Modems are
patched now, and I re-flashed it. However in the meantime, it
grabbed a new DHCP lease @ 44.24.241.55. We should really give it a
static IP/lease + DNS entry so it stops moving around...

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!
