I am now a member of the Worldwide TV-FM DX Association, or WTFDA, the only North American TV and FM DXing club. I was previously a member in 2008-2009, but for some reason never got around to renewing my membership over the years. I have, though, supported the WTFDA throughout the years via their forum and email list (both of which are valuable resources for DXers). I suggest all DXers join the club! Visit their website for more information.
