On August 23, Rush HD will be rebranded as radX. A bit of the info is posted here and so it the new logo. http://www.facebook.com/note.php?not...02859&comments
Equator HD will become eq HD, I'm guessing probably on the same date as Rush becomes radX. Although, I haven't seen any press release on it though.
Here's radX's website and eq HD's website.
One interesting thing about radX though, is that they've dropped "HD" from their name. Maybe this is a move to launch a SD version of the channel?
