Pirate Radio Recordings: Wolverine Radio

Wolverine Radio sent this SSTV image at the end of the broadcast. This one was decoded with the PC freeware, RX-SSTV.

Wolverine Radio was yet another pirate station I recorded last Saturday night (along with Radio Ronin and Radio Appalachia).

Wolverine Radio was broadcasting on 6.95 MHz in the upper side band. Their signal was very good and fidelity excellent for SSB. Lots of variety and a common “radio” theme throughout WR’s music mix.

Wolverine Radio–at least each time I’ve heard them–sends an SSTV image at the end of the broadcast. I decoded the one in their Satuday night broadcast (see image on right) using RX-SSTV, a very intuitive and simple freeware PC application.  Make sure you use the “Scottie 1” mode.

Microtelecom Perseus software updates

The Microtelecom Perseus SDR

I just received the notification below from Microtelecom. I find it very encouraging that they are still tweaking and working on the Perseus software (which is quite mature at this point). No major upgrades here, but they’re worthy updates.

Note that this is a BETA release for the client and server versions:

A new Perseus release is now in the BETA phase.
Here is the download link:

There are quite a few changes in both client and server.


-The servers map is no longer integrated in the Perseus software (when clicking on the “Show Map” button, a default browser window will open).

The link between the map and the Perseus software is done by a tool (included in the package) called mttps.exe. During the first run, administrative privileges are required to properly register the MTTP protocol.

-Buttons font rendering was modified to address some users that reported “blocky” or hardly readable labels on some buttons.

-Audio Delay: this new feature inserts a configurable delay in the DSP chain, please refer to the release notes (included in the package) for more information about it.


-Support for the delay feature

-Restarting the server is no longer needed after a DNS change

-Blacklist support: using a text file (as explained in the release notes) it is possible to reject connections from an IP address or family of IP addresses (server software settings has a new section).

Enjoy this new release!

Pirate Radio Recordings: Radio Appalachia

Radio Appalachia is the only pirate I’ve ever heard on the shortwaves which features bluegrass and gospel music. This recording was made Saturday night on 6.9349 MHz (AM).

At 8:28 in the recording below, you’ll hear Radio Appalachia’s station ID :

“Radio Appalachia, you are listening to Radio Appalachia…the free voice of the Ohio Valley. Broadcasting from high above Moundsville, West Virginia, this is Radio Appalachia.”

You then hear their signature Three Stooges audio sample and a repeat of the ID.
