Hi James, These large files are not typical audio recordings. They are specialized WAV files with encoding that represents a large swath of RF bandwidth. In this case, the files contain the medium wave band as heard by Dave Aichelman when he was visiting Hawaii with his Perseus SDR and antennas. It requires Perseus software (such as the demo mentioned by Sylvain Naud) or the free HDSDR software.
Once loaded and playing back in the host program you can tune around the band, apply filtering and modes, change AGC, passband tuning, etc. just like you can in "real time" with the receiver. The entire band is there for you to explore, and with WAV files recorded in a far away place you can experience what the band sounds like as you explore the many stations. It is this recording capability for the entire band that is the #1 feature of a good SDR like Perseus. My Mediafire.com file storage account has quite a few similar recordings made by Perseus owners from around the world. 73, Guy Atkins Puyallup, WA USA > ------------------------------ > > Message: 2 > Date: Tue, 26 Jun 2012 18:59:40 -0500 > From: "James Niven" <[email protected]> > To: "'Mailing list for the International Radio Club of America'" > <[email protected]> > Subject: Re: [IRCA] Perseus WAV Files Recorded in Hawaii Available > Message-ID: <[email protected]> > Content-Type: text/plain; charset="US-ASCII" > > Thanks for giving us the link Guy, much appreciate it! > > I have downloaded these files, how do you listen to these files? > > Thanks > > Regards, > > James Niven > Austin, Texas > > > > > _______________________________________________ IRCA mailing list [email protected] http://montreal.kotalampi.com/mailman/listinfo/irca Opinions expressed in messages on this mailing list are those of the original contributors and do not necessarily reflect the opinion of the IRCA, its editors, publishing staff, or officers For more information: http://www.ircaonline.org To Post a message: [email protected]
