L beacon 5157khz
« on: July 08, 2017, 0453 UTC »
Listening to the University of Twente SDR online, at 0450 utc. Came in at about s2, just a bit above the noise, repeated the letter "L".

Good catch, "L" for some reason is always very weak here and thus is a rare catch for me, data is as follows:

5.156.8MHz  CW  "L" St Petersburg, beacon/marker Baltic Sea & Neva River, Russia.


There are 10 Russian beaons/markers listed for that frequency from 5.153.7MHz to 5.156.8MHz all same format as "L"... ;)
Mount Piddington, NSW, Australia 3,654 feet ASL (127kms west of Sydney)

Grid Square:  QF56dj.

Yaesu FT-2000D & Tecsun S-2000 to 310 feet of wire, and a multi band vertical of dubious reliability.

Still hearing "L" on the Twenty SDR but nothing direct which was no surprise. I tuned a little lower and was copying "D". Checked it direct and there it was! 5153.7 on the TS-480. That was a surprise. Lots of noise but EZ copy. Also looked good on the fldigi and spectran waterfalls.
I am in SE Fla using a vertical.  

Edit to note I am in grayline right now. Sunset 6 minutes ago at 00:18:59

Any idea where the beacon originates and why? 0522 UTC, still hearing it via University of Twente SDR.

google Russian military HF beacons and look for the HF Underground wiki

fascinating stuff!

From footnote #21 in the Letter beacon HF Underground wiki:
"Cluster beacon was also active throughout July 2011...that "L" transmitted from St Petersburg but so far there is no evidence to support this...It moved (in freq) on July 23...and again (in freq) on July 24"(2011).  

However the  "Number and Oddities", issue 166, pp.7 cited link in the footnote points to issue 165 by mistake.

And footnote #23 links to the current IARU R1 report (2017) not 7/2011 as cited.

Most times & frequencies posted are only an approximation.
Due to the insubstantiality of any “control list” or other designator codes, they are never used.
