I realize this in not answering your question, but I thought you might like to know that some people share access to their antenna on the web at http://websdr.org/. This sdr webapp lets you listen to the airbands from their antennas basically, and each user can tune it to their own frequency at the same time.
I never ever received that registration email. Also, the content is not viewable without an account. Disappointing, especially considering the countdown to release which turned out to be a countdown to nothing.
