Pirate Radio Recordings: Grizzly Bear Radio

Leave a reply

A few weeks ago, I found a pirate I had never heard before: Grizzly Bear Radio. They quickly nullified my claim that Radio Appalachia was the only pirate I knew of that broadcasts bluegrass music. According to Grizzly Bear, they transmit from the northwest US, so the fact that I hear them at all speaks of good propagation and Grizzly Bear’s antennas.

At any rate, I did manage to capture almost their entire broadcast–nearly 5 hours!–on October 6th. Unlike many of my recordings, this one is faint at times and you’ll have to listen through the static.  Still, this is what I enjoy about pirate radio, hearing some unique audio through the static. As grandpa used to say, this “builds listening skills.”

You can download an mp3 of the full recording, or simply listen in the player embedded below.  Enjoy:

Radio World looks at DRM

Once touted as the “Savior of Shortwave,” Digital Radio Mondiale has not lived up to its hype. Proposed in 1988, with early field-testing in 2000, inaugural broadcasting in 2001 and its official rollout in 2003, DRM has had a lackluster career over the last decade.

With the allure of FM-quality audio and fade-free operation, it had appeared that DRM might revive the shortwave community. Unfortunately, it has been overcome by other events, some technical and some social. The main weakness has been alternate sources of information and entertainment, fueled by the very technology that gave DRM hope.

Additionally, in areas of the world without ubiquitous social media, DRM has yet to realize receivers at a moderate cost with adequate battery life. The very processing technology that allows improved operation using the more complex DRM waveform costs more and consumes more power than the standard AM receiver. A quick look at standalone DRM receivers over the past decade shows almost a dozen companies entering the market, only to retreat when the promise didn’t materialize.

[…]The rise of the Internet has influenced many broadcasters to cease their shortwave transmissions in favor of broadcasting over the World Wide Web. When BBC World Service discontinued service to Europe, North America, Australasia and the Caribbean, it generated many protests. The shifting of resources from shortwave to Internet and television by the Broadcasting Board of Governors, which oversees U.S. international broadcasting, further reduced broadcasting hours in the English language. […]Although most of the prominent broadcasters continue to scale back their analog shortwave transmissions or completely terminate them, shortwave is still common and active in developing regions, such as parts of Africa and South America.[…]

The article then goes into an in-depth look at both the reasons for and technology behind Digital Radio Mondiale–both on the broadcasting and receiving ends.

AFN (AFRTS) drops Key West transmitters

1 Reply

Due to budget cuts, the American Forces Network (AFRTS) has decommissioned their Key West, Florida SW frequencies of: 5446, 7811, 12133 kHz

Since the Navy provides the shortwave service as a supplementary or backup service for their ships that don’t have the Navy’s Direct-to-Sailor (DTS) capability, I’m not terribly surprised they’re downsizing. Even so, the AFN still maintains their Guam and Diego Garcia transmitters as they recognize that the, “[s]hortwave service is also an option for land-based listeners in remote locations that do not have access to local or satellite-delivered AFRTS full Satellite Network (SATNET) services.”

AFN/AFRTS Shortwave Frequencies (note: all broadcasts are in USB)

  • Diego Garcia:
    • 12,579 kHz daytime
    • 4,319 kHz nighttime
  • Guam:
    • 13,362 kHz daytime
    • 5,765 kHz nighttime

Personally, I’m a little saddened by the cuts as the Key West facility was the easiest for me to hear in the US, though I routinely hear Guam and Diego Garcia. Not familiar with the AFRTS?  Check out our recent post.
