Shortwave Broadcast / Re: firedrake wiki page

How often do they change frequencies?


I didn't look for them at all over the past 3 years or so, until this month.  So I'm not sure.  But none of the frequencies I logged back then are active now.

The most useful information is probably:

* Look at recent DXLD issues for logged frequencies
* Listen to the recordings so you know how to identify it
* Scan 6000 - 16000 kHz
* Tune to frequencies used by Sound of Hope (and other broadcasters known to be targeted, although I don't have this info myself)

I put all of my logged Firedrake frequencies on the page into a table.  But the mediawiki tables are difficult to maintain, so maybe this isn't the best format.  And maybe we only should have the past 3 years or so worth of frequencies listed there.  Any thoughts?

There's a Firedrake page on the HFU wiki: http://www.hfunderground.com/wiki/Firedrake

We could add external links here, links to recordings, and perhaps frequencies that we log.

Spy Numbers / V02a on 5883 kHz, 12 Sep 2011
« on: September 16, 2011, 0543 UTC »
12 Sep 2011, 5883 kHz, Spanish numbers station.  Eton E5, located in San Francisco.  Given the frequency and the day, it looks like it would've been around 0700 UTC.

I could just barely hear it in San Francisco on my Eton E5 with Degen DE31 active loop antenna.  I identified several of the songs, some from memory, some with Shazam, one with a Google search with the lyrics.

You can search fcc.gov for AM stations in Mexico:

I get Mexican AM stations here in San Francisco, although I don't pay much attention to them. I'd be surprised if one plays 80s music with English lyrics.

Shortwave Broadcast / finding firedrake transmitter(s)
« on: September 17, 2009, 2000 UTC »
Part of my fascination with China includes a fascination with the firedrake/firedragon jammer.  It's not enough for me to know that the audio for these broadcasts come from China National Radio satellite feeds (as mentioned at http://www.satdirectory.com/firedrake.html) or that direction-finding has revealed Hainan island as the probable transmitter location (as mentioned at http://www.iaru-r1.org/index.php?option=com_content&view=article&id=257:fighting-the-chinese-government-firedragon-music-jammer-and-sound-of-hope-broadcasting-soh-taiwan&catid=66:iarums-success&Itemid=189).  I want to see a satellite photo of the transmitter site.  Does China use this site for any legitimate broadcasts?

Finding this transmitter site with satellite imagery doesn't seem feasible, as the island is over 13,000 square miles, and Google's images are only high-res for the heavily populated areas.  I don't know how precise of a location the direction-finding has revealed; that's something I want to read more about.  Suggestions on how to find this transmitter site would be appreciated.

Other / Russian on 8807 kHz ssb
« on: September 12, 2009, 0831 UTC »
12 Sep 2009, 0823-0827 UTC, 8807 kHz ssb.  Received in northern California, USA; came in strong on my Eton E5 + wire antenna. I heard what sounded like two-way voice communication, although I only heard one person speaking with periods of silence in between.  It was a male speaker, and the language sounded like Russian.  Who would be using that frequency?

Other / Re: 7690 kHz, constant hum, 30 Aug 2009 @ 0715 UTC
« on: August 30, 2009, 1805 UTC »
Is the hum 50/100Hz or 60/120Hz?

Those mystery carriers are a source of head scratching ???

I've been hearing one of those on 8361 KHz for months with no modulation.

Peace!

I just used a tone generator, and 100 or 120 Hz sounds similar to what I heard.  I was using AM on my radio as well.  Thanks for the info; I'll post more logs here if I find it again.

Other / 7690 kHz, constant hum, 30 Aug 2009 @ 0715 UTC
« on: August 30, 2009, 0726 UTC »
On 7690 kHz, I came across a strong signal with a constant humming sound.  If I tune up or down 5 kHz, it's not audible anymore, leading me to believe that this some kind of broadcast.  The tone reminds me of the sound of a small prop plane flying overhead, but at a constant pitch.  There's volume fluctuation, but I can't tell whether or not it's due to fading.

EiBi doesn't list anything for this frequency, and it isn't in a broadcast or ham band.  Unfortunately, I'm getting a lot of noise, so I can't make a decent recording.  Any ideas what this could be?

In my account settings, I have "Hide email address from public" checked.  But if I view myself in the members list, and hover the envelope icon, my email address is shown.  How can I get my email address removed from the members list?
