A Video Introduction to MW DXing - by Nils Shiffhauer DK8OK
Sunday, February 7, 2010 at 11:07PM What's all the fuss about? If you're a Perseus owner who has never explored foreign medium wave DXing before, Nils Schiffhauer DK8OK presents a short video about the basic techniques of tuning the interesting and challenging stations found between the 9 or 10 kHz channels of your local medium wave outlets:
Thanks for producing this excellent MW DXing intro, Nils! If you wish to see other similar videos featuring the various ways you can use the Perseus receiver, CLICK HERE for Nils' channel on YouTube.
Share Your Perseus WAV Files!
Wednesday, February 3, 2010 at 1:38PM What does longwave, the tropical bands, or medium wave sound like from your corner of the earth? Please consider sharing your Perseus WAV files with others. I'm particularly interested in WAVs recorded in regions that are poorly represented in the WAV files listing (sidebar to the right), such as Australia/New Zealand and Asia. For that matter, are there any Perseus owners in Africa who would like to participate?
I have ample file storage space available for hosting Perseus WAVs, and I'm happy to post your recordings for others to enjoy. In addition to files containing DX stations heard at your location, I'd like to feature medium wave daytime local/regional stations recorded at local noon in particular. This will give Perseus owners actual IDs from stations in your area, to help with their own DXing.
Here are the requirements that I think would be best for sharing:
- 1 minute or less, or 2 minutes (max.) in length WAVs, centered on (or starting near) the top-of-the-hour [example: 11:59:30 to 12:00:30 for a 1 minute recording]
- Less than 1 GB in size (e.g.: 1600 kHz, 2-minute Perseus WAVs are 930-960 Mb)
- Provide information: center frequency, recorded bandwidth (800 kHz, 1600 kHz, etc.), and UTC time and date of recording; your location and other notes about antenna or conditions
- Files can be trimmed with Chuck Hutton's useful Perseus WAV Chopper utility (see Interesting Links above)
- Photos of your antenna setup are interesting too
Maintenance Release 2.1i Available for Perseus
Monday, February 1, 2010 at 11:59AM A new release of Perseus, version 2.1i, is now available which addresses a few bugs observed in 2.1H:
- Preselector switch button hw/sw misalignment at software startup
- System date changes make the software stop working(*)
- The v2.1i version also outputs the Markers Log File in a more readable format
Perseus' designer, Nico Palermo IV3NWV, also mentions as the software may contain options offered on a evaluation period basis and relies on the software installation date to enable them, the options will be permanently disabled if a system date change is detected.
In addition Nico says I have also tried to address the "black screen" issue but I need the feedback users to see if it has been completely cured or not.
Beside this the v2.1i is no so different from the previous software version and will NEVER expire. What will expire are just the software software options which are not offered for free in the basic software version.
If you are not interested in them, simply check the label "Don't show this dialog again" in the initial dialog "Perseus Software Optional Features" and you won't be bored by them anymore.
If you are ALSO interested in any of the options you would just need to apply for a software options license. After paying those you might be interested in you will get a personal license file which will enable the options permanently.
You may download the new version 2.1i from the following link:

New Perseus WAV File from Finland Reveals Northwest USA, Philippines & Australia DX
Friday, January 22, 2010 at 11:45AM Tarmo Kontro from Finland shares another interesting WAV file captured with his 250m BOG antenna, oriented at 45 degrees bearing.
Tarmo's lonely BOG antenna feedpoint rests under a blanket of snow, visited only by a curious rabbit...note the footprints.
He comments that this December 8th, 2009 Perseus file includes widespread reception on medium wave: from Western North America, Hawaii, Alaska, to as far west as Australia and the Philippines.
Check out Kontro's new 343 Mb WAV file in the sidebar on the right, under the Europe section. It is 45 seconds long across the top of the hour at 1200 UTC, with a frequency range of 200 - 1800 kHz.
