OK, here's the deal. The WebSDR server is running on a Linux box here and I have been able to connect to it locally and it looks like it's running correctly. I changed my No-IP.com host settings to forward port 80 to the port the server is running on (8080).
That means you should be able to reach it without the port number, just ti2na7u.zapto.org should suffice. Of course, you only need your browser (Java enabled) to see the radio. I have the server set to support 4 simultaneous users (I only have a 768K uplink and I need some of that for myself!).
I've seen some ops connecting in the last hour so I know it's working. Even though I have the correct setting in the config file, however, the server is not yet listed at websdr.org.
The Softrock is connected to my 400 foot Skyloop with the trusty Johnson Matchbox for the antenna match. The radio is being powered by the little variable PS I wrote about earlier and a 9V wall wart.
