Natteri Swamy's tele-upanyasams in October 2010 are here in MP3 format.
Actually adiyen tried to present all the October upanyasams as one file. But uploading restrictions prevented that effort. Kindly excuse me. But there are so many freewares for joining mp3 files. If desired they may be downloaded and these files may be joined together as one file.
