Below are Perseus spectrum recordings available for download for anyone interested. These are Perseus WAV format files compressed using WinRAR, they are not audio files. Perseus SDR software (or equivalent) is required to play back these spectrum recordings. If you don’t have a Perseus SDR, then go to Microtelecom’s download page and grab the free demo version which you can use to “play back” these spectrum recordings. All recordings were made by me at my home location in Michigan, USA unless noted using a BOG antenna of about 500 feet in length, unterminated oriented E-W.
Decent conditions November & December, 2010 that brought in several longwave broadcasters from across the Atlantic:
This recording covers about 4 minutes beginning at 0137 UTC focusing on 5828 khz to 7428 khz from October 10th, 2010 and includes numerous shortwave broadcasters and aviation utilities, 41 meter amateur band, etc.:
February 9th, 2011 saw nice conditions on the 49 & 41 meter shortwave broadcast bands, so I captured the moment. This recording covers 6000-7600 khz for a duration of about 5 minutes centered at 0300 TOH:
Here’s an odd one – perhaps a station jamming E10 on 6840 khz – very strange:
Here’s a bandscan of the 49 meter band with a wide variety of shortwave broadcasters present covering 5635-6435 khz. Check out the spook signal on 5800 khz:
Australia’s ABC Domestic Service was coming in recently on a cold November morning, and in my excitement of finally hearing these outlets on the 120 meter broadcast band, I made a spectrum recording. There’s a trace of a signal on 2368.5 khz which I presume is the carrier from Radio Symban.:
A presumed very low power pirate beacon can be heard in this spectrum recording on 4094.36 khz CW ID’ing as “AZ” – perhaps a desert beacon from Arizona?
Sample recordings containing strong DRM stations resulting in very good decodes:
There was a lot of activity during the weekend of January 15th, 2011, all represented in the long captures below. At one point, there were at least four pirates operating simultaneously on the band! Represented here are stations WHYP, Undercover Radio, WEAK Radio, KBLK, Pirate Broadcasting Network, Radio Magnetic Pole, Wolverine Radio, and possibly others:
More spectrum grabs from the 15th are currently being uploaded and will be linked here soon.
Here’s thirteen minutes of a morning broadcast capturing Radio Ronin Shortwave including sign-off:
MAC Shortwave was captured way down on 4275.9 khz on December 4th, 2010 signing on at 0500 UTC until 0640 UTC sign-off. Guyana and Costa-Rica are also present in this spectrum grab:
WBNY being relayed by MAC Shortwave on 3276 khz beginning at 0014 UTC on December 19th, 2010, and then into MAC Christmas programming:
Long captures of various US shortwave pirates on October 31st (Halloween night), 2010:
6860 khz (2354 UTC) & 6950 khz seem to have mixing products from the MW band at times***

6977 USB – 2214 UTC – Non-pirate MARS net traffic
Mixing products of local BCB stations pop up periodically (like WGVS/WGVU 6860, 6940, 6950 khz, etc.) – My external preselector was not switched in during this session – dohh!
