HF Beacons / Is the Desert Whooper OK?

« on: March 31, 2024, 1643 UTC »

For the past two weeks, DW signals have been considerably weaker than usual. Just me, or has anyone else noticed it?

In the past, DW was often a couple of S-units stronger than the Coast Slider, but now the situation is reversed. DW was typically S4-5 on the KFS and KPH SDRs, except for afternoon fades. But lately it is only S1-2, if I hear it at all.

 Maybe night time only?

I think you are right.

I have not heard it during the daytime (here on the West coast) but only at night. And looking through the reports in this thread, KOK has only been logged at night.

Seems to be gone now. Its signal was S4 to S5 when first reported, but I haven't heard it for the last two days.

HF Beacons / Re: Long Dasher On 4069.4

« on: March 22, 2024, 0311 UTC »

Tuned to 4069.4 and waited for the dasher to start up this evening. At 0225Z (7:25pm local - a few minutes past sunset), it started up with a series short chirps (previously mentioned above) before settling down to the usual dashes. S2-S3 on the KFS Omni SDR.

Also copied the 2nd harmonic on 8138.9 -- much weaker and just above the noise.

 It turns out that the 4069.4 long dasher may be a night-time only beacon, starting up at approx 1945 PDT (at dusk here on the west coast) and is gone by sunrise. At night time, it has a good signal using the home RX and also the west coast SDRs. I hear it in the evenings and night, but never during the day.

For the past three evenings, I have observed it starting up with a series of short chirps for ~30 seconds before settling into the usual long dashes. It could be on a timer or maybe it waits until dusk. It'll be interesting to observe the start times as the days get longer.

HF Beacons / Re: Beacon on 4.069

« on: April 05, 2023, 1920 UTC »

Hearing an evening beacon at around 4.069 here in So. Cal.

Good ears! I haven't heard this dasher for many months, but now hearing it on my home RX (on 4069.4) again in the evenings and early mornings, S2 to S3.

 Here's a thread from last March: https://www.hfunderground.com/board/index.php/topic,95110.0.html. The fact that it fades out at sunrise means that it's skywave propagation to my bay area QTH and located farther away than NVIS range (say 500 miles). Any ideas regarding a general location?

HF Beacons / Re: Coastal Slider Back On 4109.5

Agreed, CS now seems to be a daytime-only beacon, and then only in sunny weather. During California's recent 'atmospheric river events' it was was off the air for days.

CS actually keeps going a few hours past sunset. It's now about 10:30PM CA time and it's strong on the KFS SDR. But it'll be dead by morning.

I caught CS in 'wakeup mode' this morning around 9am. Irregular and shortened beeps for maybe 30 minutes, beeps a couple of times, stops for a few seconds, then chirps again, etc.  Seen on the KFS SDR, some of the beeps have an interesting signature and are spread over a couple of kHz (caused by low battery voltage?). See the attached screenshot.

I'm hearing it on the KFS Omni SDR this evening at 0230Z.  Not strong, S2 or so. A .5 second dash every 3 seconds on 4094.1 .

I think CS has become intermittent. For a few days (after Jim's post) I looked for the usually reliable CS just after sunrise using my home RX or the SDRs. Nothing but static.

But last Thursday something interesting happened: suddenly, around 0850 local (CA time), it came on. I had left the RX on after checking at 8am. However the 'slides' were weird and oddly formed - erratic and shortened,  in groups of 2 or 3 with long pauses in between. This went on for 10 minutes and then stopped. Checked again several times that day and it was not heard again. I noted the CA weather that day was a mix of rain, clouds and occasional sun.

Today I checked at 7am, and again nothing was heard.  But re-checking at 10am - there it was sliding away merrily, with a strong signal. So CS had started up sometime well after sunrise today. And it's still there at 8pm. North/Central CA weather was sunny all day. Maybe CS is having charging/battery problems?

Yes, it was back to S9 on the KFS SDR for awhile today, but then went back to just a whisper this afternoon. Now (at 0150Z) it is abruptly going from S9 down to S2 mid-whoop - or even mid-character! DW may have an intermittent connection in its PA, or its antenna system.
