HF Beacons / 4093.2 New Dasher?
« on: February 22, 2021, 1545 UTC »
I noticed this on the KFS SE Kiwi and did not see it in our master beacon list. About a 1 second dash rate. Can't hear it on my receivers at home.

Has anyone caught much traffic in the ITU channelized HF spectrum between 4.063 and 4.438? I trolled through the Utility posts and did not immediately spot any loggings. Thanks!

HF Beacons / New Dasher 4097.22 KHz ?
« on: December 10, 2020, 1607 UTC »
Second day I've seen this one on the KFS Kiwi SDRs. Suspect this dasher is solar powered as I saw it suddenly start transmitting about 5 minutes ago with a bit of instability before settling down.

4097.22  Dasher 2 sec on 2 sec off

HF Beacons / New whooper beacon on 4095.65
« on: November 16, 2020, 2117 UTC »
Sends the sweeping signal"Whoops" 15 times then CW ID's with the letters "DW". Maybe a "Desert Whooper"?

Weak with some fading on the KFS Kiwi SDR using the SE antenna.

Utility / Emergency traffic on 8843 KHZ ARINC
« on: November 07, 2020, 0150 UTC »
Came in late on a conversation of a flight reporting to San Francisco ARINC that an aircraft had gone into the water. Said he had talked to the aircraft up until it went in. Apparently had already provided coordinates and was requesting a USCG response.

USCG came up on frequency and gave a rough position of  -garbled-.

Started around 0140Z 11/7/20

EDIT - I can see what I thought I heard for coordinates makes no sense so will hope to catch the USCG update

HF Beacons / The new "L" Beacon
« on: May 13, 2020, 1407 UTC »
4096.130 KHz  "L" Beacon!  Weak but readable..Popped out of the noise then sank away.


Credit goes to mark-n-nut (Mark-In-North-Utah?) for this discovery yesterday. I hope the beacon stays on the air a long time.

Its there!  It comes up out of the noise this morning but only for a few seconds.  Have heard a W and dits is all so far.  Prop is just terrible for me here.  Has the band gone long...  or short...  I think long.  Will have to go and wander threw some SDR's and see.  While listening and watching for windy I have been seeing a signal on about 4096.1 sending the letter "L" have you heard it?

73, Mark

The signal is a great catch but is not an HF beacon.

HF Beacons / "A" on 2MHz beacon off the air?
« on: September 28, 2019, 0416 UTC »
I'm not sure exactly when I stopped hearing it since band conditions have been fickle but, I made a point of listening early today and heard nothing. Tonight I'm not hearing it and also checked some web SDRs and other sites but without any luck. This beacon has been super consistent over the years so I am surprised I am not catching it all.

Hopefully someone has heard it today! Let me know!
