My error on the time!! Your beacon first heard a 2300Z with 569-589.

HF Beacons / Re: 4107.8 slow dasher
« on: March 21, 2022, 0213 UTC »
The signal surrounding the two what appears to be CW signals a 4109.00 and 4107.80 are synchronizing signals for an independent sideband biphase data waveform offset above and below the 4109.00 and 4107.80 synch signals. During the period of the long dash on those two frequencies, bi-phase digital data is sent on the synch signal’s upper and lower sidebands, given that, the whole thing is a fairly complex waveform. The data sent on either sideband is very different coding, although both data streams are bi-phase; there’s no signal/data related correlation in either time (bit rate) or frequency domain of the two.

The bottom line, Teotwaki has it right, these are no beacons and very “un-piratey”, the modulation waveform are some sort of commercial or Mil point-to-point data signaling.

My apologizes for all the verbiage, but became fascinated with the signaling process, never saw it before and my curiosity got the best of me over the last week and spent a ridiculous amount of time in the analysis of the signal waveform.

Strong signal here to tonight for some reason. Usually I don't get a copy on the Slider, but tonight at 0420Z it's 589?

Interesting Teotwaki? Same at this location.

Over the few years I've monitored "A", I always thought it might be groundwave to me, but after this winter "A" defiantly has a sky-wave component to it, fading out after 0300Z.

Although "A" can just barely seen on the Kiwi, even with the QSB, its gone from sight and sound after 0400Z. Keeping that in mind "A" is very good copy at TOKEN's Kiwi site (579) as well as Utah, Las Vegas and Winnemucca Kiwi sites (579 respectively).

Nice signal in the extreme south!! 459 with QSB at 0354.

Congrats on a good job!!

This is the first night I've heard your beacon, skip gets a little long here at this time.

HF Beacons / "L" at 4095.11
« on: February 15, 2022, 0330 UTC »
Is anybody copying "L" at 4095.11kHz? It's 459 at 0309Z. sending "L" at approximately at a 5 sec. rate

 Some time ago I heard an " L" Beacon regularly at 4096.150, but this is the first time this evening for the 4095.11kHz signal for me.

"L" is 589 on the Utah Omni at 0326Z.

F booming in here at 1456. A little unusual after sunrise.

HF Beacons / Re: 4100.04 KHz "H"
« on: January 22, 2022, 1838 UTC »
Yes, excellent use of DW, rather than the brute force approach to HF propagation traditionally used by amateur radio. In the case of HF beacons at 4MHz (with the exception of DW), we unfortunately don’t know their general location preventing much in the way of path identification.

 Additionally, one of the best HF path and relative path quality identification tools easily available to most these days is WSPR and to some extent QRSS beacons.

As far as “F” and “H” are concerned, notionally it’s always interesting to attempt path estimation based on time of day, ground wave and D-layer propagation. “F” is a little easier to work with from this location; “H” remains more of a mystery.

Zeak,

In reference to my earlier reporting on beacons “H” and “F”,. The latest was copying of “F” starting at 1303Z as it came up out of the noise floor and rose to a very good signal (589) by 1443Z. Anyway, as for “H”, shortly after the 1440Z report and almost coincidental with the local sunrise (1449Z) I could copy beacons “H” and “F” simultaneously, “H” was weaker but readable at 549 and “F” at the usual 589. Since, from 1510Z “H” has slid, almost abruptly back into the noise.

 So, I guess the point is, both beacons are still there, at least from this location and allowing for propagation.

Yes, I can also copy "F" here too starting at 1303Z, 579 with QSB. Must be a skip thing because the last time that frequency was checked here was 1212Z and nothing heard.

Well, good!!

And, here I thought "H" might be here to stay for a while, but nothing heard at 0452Z after a good showing earlier. Maybe its the propagation....maybe not?

"H" reminds me of "L" which has been in and out of 409x.xx kHz for the past couple of years, both have very good coverage in the western US.

Sometimes we have to be patient and give credit where credit is do.

All evening I have been copying "H" at 4094.12kHz, although weak but readable, its in there. "H" first popped out of my noise floor at this location at 0332Z and is still about the same at 0449Z with a little bit of QSB.

Although 75m skip is long right now, "H"'s location always eludes me.
