Former YHWH up 7405 kHz AM, started at 0313 UTC, Dec 10, 2016.

(edit)  Either off mid sentence, or a very deep, sudden, and long fade at 0335z.


Someone posted a plan to transmit on Amelia Earhart's frequencies from one of the islands she may have crashed on.

Details, few though they are, here :  http://www.antiqueradios.com/forums/viewtopic.php?f=5&t=311243

It looks like this is not very well thought out.  The times of transmission will be at 1900 UTC (1400 EST and 1100 PST) on Dec 14 and Dec 15, 2016.  The frequencies used will be the 3105 and 6210 kHz that Amelia Earhart used.

Whoever planned this does not have a deep grasp of propagation.  Those frequencies, by that time of day, will have essentially shut down, as there will be a daylight path from the island to the US and those freqs are regional, at best, during the day.


HF Beacons / Possible new beacon 4096.86 kHz Nov 12 2016 1345 UTC
« on: November 12, 2016, 1511 UTC »
A possible new addition to the 4095 / 4096 cluster of beacons.  This morning I saw a short duration ditter, about 0.15 sec long dit about every 0.95 second on 4096.86 kHz.  I noticed it about 1345 UTC on Nov 12, 2016.

The ditter was very weak, and had long fades to completely gone.  It is possible it is cycling on and off like a few other beacons do (Shorty on 7998.3 kHz and the two unnamed beacons on 2008.4 and 2016.7 kHz), but really it was too weak for me to be sure.

Here is a shot of it, note that in this shot the other 4095/4096 beacons are not present, there was some odd propagation this morning as these beacons are normally seen here quite well:

40 minutes later Viking and Haystack faded up out of the noise, and the new beacon could still be very faintly heard.  As this was right about sunrise and it was a bit cloudy, the Inyo-Whooper is not seen, it is a daytime only beacon and turned on a while later.

And 30 minutes later Inyo-Whooper was on solid, but no sign of the new beacon...if it is one.


So far unided station, 6940 kHz USB, started at 2245 UTC, November 6, 2016.  Good signal in the Mojave Desert.


This morning when Stumpy came online the pause between dits and the dit length is changed.  I do not try to catch it every day, but the last time I did (a few days ago) it was still about 22 seconds from dit to dit, and dit length about 0.17 sec.  But this morning I caught the turn on at about 1429 UTC, and it was 19.37 seconds dit to dit, and dit length is only 0.15 sec.

I thought at first it may be a "just turned on" thing, but an hour later it is still on the same spacing and length.  Also, the freq is slightly higher than it has been.


Utility / USCG DRM, 5200 kHz, DRM mode, 0110 UTC, 06 November, 2016
« on: November 06, 2016, 1340 UTC »
An unknown (to me) DRM signal on 5200 kHz, noticed at 0110 UTC no 6 November 2016, however looking at the waterfall it has been there for some time.

So why aren't I putting this in the Shortwave Broadcast section?  This freq does not appear on any DRM broadcast list I can find, and while the signal has never been strong enough for me to get audio decode, when the station has gotten strong on short peaks the ID/Tag under DRM keeps reading "USCG Journaline".

When I checked this morning, starting about 1300z, the DRM was still present, signal is a bit stronger, however Chinese OTHR is killing the SNR, so still no decode beyond the occasional ID/Tag as above.


So far unided spooky sound FX on 6955 kHz USB, 0128 UTC, October 29, 2016.  S7 or S8 here in the desert.

Into bells with beeps like heart monitor at 0131z.

(edit) closer to 6954.9 kHz, USB.

(edit 2)  Never got a verbal ID, but SSTV at 0154 had Pee Wee on the chest.


UNIDed station 6935 kHz USB, with music, 0055 UTC, October 29, 2016.  Very weak here, can tell it is music, but little else.  Seems to be lots of high tones in it, maybe pipes or something?

(edit) And off 2 minutes after I posted this.  It had been up quite a while, multiple songs, before that.


Another possible new ditter heard from.  7000 kHz, Oct 27, 2016, 1020 UTC, but I am pretty sure I have heard this at other times also, about 0.21 sec dit sent about every 1.39 second.  Periodically I see it send an extended dash, sometimes several seconds, as if it is hanging up.  There may even be some kind of modulation on it when it does this hang, but it is too far in the noise for me to be sure.


HF Beacons / New ditter maybe, 7000.68 kHz, Oct 22, 2016, 1700 UTC
« on: October 22, 2016, 1913 UTC »
There appears to be a ditter on about 7000.65 kHz.  I am pretty sure I have seen this ditter before, but it is such a long period and so weak I always thought it was noise / RFI / something else.  But today it is strong enough to be clear, this is not local noise.

It is a dit, about 0.17 sec long, sent every 22 seconds.  There is a very slight chirp on the dit.  The frequency at 1700 UTC was 7000.68, and at 1900 UTC it was 7000.63, so there is a little drift to it.

(edit) This signal has definitely been here for a while.  I have a recording from 2 weeks ago with it clearly present, and one from several months ago with what is probably the same signal in it.  I'll have to look back at older spectrum recordings, if I have any for that freq range, and see if I have any older that include it.

(edit2)  It turns out the 6990 to 7010 kHz range is not one I record often.  I have a recording from early October 2016 that clearly shows this ditter there.  I have a recording from July 2016 that clearly shows it present.  I have a recording from Feb 2016 that may show it, there is a lot of interference and I am not 100% sure.  And I have a recording from early Dec 2015 that does not show the ditter there at all.  So, at a guess this ditter showed up after early Dec 2016 and before July 2016, with a reasonable possibility of between early Dec 2015 and Feb 2016.

(edit3) This ditter can be heard on other remotes in California, and was also reported as heard in Washington state.


Other / Pips network up, multiple frequencies, 1403 UTC, 09 Oct, 2016
« on: October 09, 2016, 1429 UTC »
The oddity Pips network is up today, as it was yesterday.  Noticed it at 1403 UTC, 09 Oct, 2016, not sure how long it has been up today.  0.125 second long dit every 6.0 seconds.

(edit) This set off air at 1513 UTC.

20050 ?  Related to 20400?
20400 ?  May be unrelated to Pips
20950 ?  Related to 20400?

Freqs noted so far, will probably find more and add to the list as found.
