Hi OpenHPSDR,
with the patient help of John Melton, G0ORX/N6LYT, I was able to
get my Mercury receiver online on the Internet. John has made two
movies to show reception in the UK of my Mercury RX in Chicago,IL
USA: http://g0orx.blogspot.com/
You can access John's Mercury Receiver in the UK here:

Thank you John for pushing the state-of-the-art and demonstrating
the power of Java to integrate with a web browser to show a full
panadapter + waterfall + audio. I think this is amazing! Browser
access has been a great challenge for SDR Hams all over the world.
*Unlike* WebSDR, John has made his invention *totally*
OpenSource. I compiled it with NetBeans (from Sun Microsystems)
and plain vanilla "C" on my Ubuntu 10.04 mITX.
My setup is a Mercury + Ozy + Atlas graciously loaned from Dan
N4XWE. The CPU is a mITX Atom 330 running both the Java server and
the DSP engine that John so cleverly separated for portability.
John allowed me to change my panadapter line to GREEN to
differentiate it from his white on black display :-)
It is a true privilege to participate in this level of
experimentation. John has been very patient with my stupid
mistakes and novice Linux knowledge. Thanks for making this
possible John!
