HF Mystery Signals / UNID digital 6951-6955 and 6961-6965, 0041Z 16 January 2023
« on: January 16, 2023, 0049 UTC »
This is S9+ at my location, and I've never seen it before.  The closest thing to it on the sigidwiki visually is CLOVER2000, but it's listed as being 2kHz wide and these signals are both 4kHz wide (unless of course they're each two transmissions immediately adjacent, but it doesn't sound like the samples on the wiki.)

Started playing REM, "Man on the Moon", then cut to Simon & Garfunkel, "The Boxer".  S6-S7 in central PA.
 2347 UTC Zeke's Attic ID

« on: September 28, 2019, 2035 UTC »
unknown atmospheric music with occasional station ID, S9+20 in central Pennsylvania

OFF abruptly at 2036 UTC, but was dropping out occasionally while I was listening to it

European Pirates and Private Stations / Radio Pushka via Radyo Oleg 6965 USB, 0006 UTC 25-March-2017
« on: March 26, 2017, 0007 UTC »
Caught the end of a sign-on with the DJ saying something about being from Europe, then into pop music in what sounded like Russian.

Hard to tell what's being played due to deep fading.

Other / UNID SSTV on 6952 usb, 1930 utc 24 Dec. 2016
« on: December 24, 2016, 1933 UTC »
Saw a suspicious signal on the SDR waterfall and jumped on it in time to catch the last half of a greyscale test pattern with no ID.


Fired up again @1934, big S9+20 signal, biggest signal in the band by far, but still just a grey bar test pattern with no ID.  (There was a presumed CW ID at the end, but I don't speak CW and I didn't record it.)

Currently hearing a female voice reading four groups of five numbers, then Amazing Grace on bagpipes, repeat.

Other / Gasparilla Pirate Festival special event station W4G
« on: January 25, 2014, 1545 UTC »
SSTV active on 14228 USB.  Their web page at http://www.qrz.com/db/W4G says 14230, but I suspect they moved down because Saturdays are the IVCA Net day on 230 -- although I haven't seen much of the net today.  They say they're going to be on 7171 also, but I haven't looked down there yet.

10/11 meters / data bursts on 11 meters
« on: December 15, 2013, 1509 UTC »
What are these data bursts I keep seeing on 11 meters?  I see them on other bands sometimes, but they seem to be almost constant on 11.  They're almost 10kHz wide, looking sort of like DRM, but they usually only last for about a second.  Once in a while one will go for 2 or 3 seconds.

VHF/UHF Logs, including satellites and radiosondes / NOAA-15 APT anomaly
« on: December 07, 2013, 2309 UTC »
Seems like every time I'm receiving NOAA-15 lately, about halfway through the pass the visible sensor will change gain (or something), going from a normal image to either almost all black or almost all white.  The infrared image is unaffected, and NOAA-18 and NOAA-19 don't behave like this.  I assumed that something was broken on the satellite, but the POES status page doesn't say anything about it.  What's going on?

General Radio Discussion / SSTV freqs?
« on: November 30, 2013, 1620 UTC »
Other than 14230 and 27700, are there any other bands that still have analog SSTV on a regular basis?  I've checked the calling frequencies that are listed in the file that you can find all over the place by googling "sstv nets", but I rarely if ever hear anything, other than digital on 7173 and I'm not really interested in digital.

North American Shortwave Pirate / My New Underpants, 6925.18 AM, 1355Z 11/02/13
« on: November 02, 2013, 1357 UTC »
S5 signal in central PA, frequency measured with HDSDR ECSS mode

Playing what sounds like 60s pop tunes, maybe British, none of which I recognize.

North American Shortwave Pirate / UNID 6925U, 0306Z-, 10/27/13
« on: October 27, 2013, 0316 UTC »
Just caught a brief transmission.  Two SSTV pictures which I can't make out anything at all in for all the noise, then a few lines from Rush "Driven", then a few bars of a tune I didn't know, then off.

Now back on as I'm typing this at 0315Z, much stronger (S9+), don't know the song.

Got a death-at-sea theme going with "Wreck of the Edmund Fitzgerald" and now an excerpt from Iron Maiden's "Rime of the Ancient Mariner".

04:16 ID which I can't copy
04:18 The Clash

North American Shortwave Pirate / Black Cat Radio SSTV, 6935 USB, 2331 UTC, 4/2/2013
« on: April 02, 2013, 2339 UTC »
Was listening to Ronin on 6925 when I saw a suspicious-looking signal start up on 6935 on my SDR screen.  After fumbling around trying to find my copy of MMSSTV, I received the following:
