The Network

One of the main objectives of the Fringe Dwellers is helping amateur radio astronomers coordinate and collaborate on joint observations. A nice thing about RA is that observatories a long distance apart, working together, can perform some really nice science!

This section of the site is dedicated to letting each other know about where we're located, what equipment we've got and what we can offer each other.

If you perform a joint observation we'd be keen to hear from you! We would also appreciate it if you could let us know the results. We're always on the lookout for work to include on the Features page. Fame and fortune is *sure* to follow (...well, maybe not ;)

The table below summarizes the observatories currently registered as part of the network.
