KKOB 770 tower ballooned.
770, KKOB, radio tower down again by Fiesta balloon clipping guywire. As happened before exactly one icosayear ago.

Here`s an audiovideo, set to music, isn`t that nice?

One KOAT report says the downed tower was one they rely on at night. So that means it can`t go direxional to protect WABC. KOAT TV refers to KKOB as its “media partner“ — ha, long divorced from KOB TV. Check for it tonight. More bits:

Geez, people don`t know the correct term is guywires:
“”At this time, it looks stable. We have no sagging in any of the guidelines. The anchors are in place. There is only one guidewire that’s going over one of the anchors from the previous tower that collapsed. So, at this time, we’re we’re very hopeful that the second tower is structurally stable,” Harris said.“

KOB, originally, should have known better than to locate its 50 kW towers so close to an area which would eventually be filled with HABs (Glenn Hauser, OK, WOR)

The FCC reports that 5 (up from 4) AM stations are off air.
I found a remote KiwiSDR near Ocala FL that appeared to be operational normally.

A quick bandscan at 2300utc suggests the following stations may be silent
WTBN 570 Pinellas Park
WBOB 600 Jacksonville
WWBA 820 Largo
WTWG 910 Plant City
WORL 950 Orlando
There could be others. As they are not heard  on this SDR http://21084.proxy.kiwisdr.com:8073/

AWR. This is the antenna currently in use for 1395 kHz:

And this is the transmitter, whereever this used solid-state rig came from:

Does AWR’s “Peterson is gone, so let’s cancel everything” include mediumwave as well? The question concerns besides 1395 kHz also 1548 kHz at Trincomalee-Pekara, which in this case could soon close altogether.

All MW antennas were replaced and slightly relocated.

Some have cage antennas, some don’t.

KWRM 1370.
I’m listening to KWRM tonight, they are definitely back on the air after a lengthy absence. TOH ID in English. Mentions Corona and Rowland Heights. Ads both in English and Chinese. Very pleasant Chinese music.
On my drives to Las Vegas I sure miss seeing their former multi tower site near the intersection of the 15 and 91 freeways. It would just shimmer at night.

Space Weather

A SOLAR STORM JUST HIT EARTH: As predicted, a potent CME hit Earth on Oct. 10th. The impact sparked a severe geomagnetic storm with significant ground currents in parts of the USA. Storm levels are subsiding now, but still strong, and they could surge again as Earth moves deeper into the CME’s wake. Mid-latitude observers should be alert for auroras after local nightfall.

Back on air in the Netherlands !!! I’ll post a video later, but low power AM station “EYE AM radio 1134” from Alkmaar came through very nicely today.
It was S 6.5 last year, but now exceeds that in terms of signal strength with S 7.5 thanks to a higher antenna.
My QTH is Wâlterswâld in Northern Netherlands.
Eye am radio 1134 Khz, 100 Watt PEP, 25 Watt carrier indeed. The most used power for LPAM in the Netherlands.

FL emergency MW may increase audibility.
Be on the hearout for FL MW stations which if they have power may be running day power/nondirexional facilities at night, less/not normally audible where you may be.

Armenia and Tajikistan

About superlong Zarya MW transmitting antennas, Armenia and Tajikistan.
In our work at both Gavar and Orzu we inquired and the local folks had essentially no technical information on the Zarya antennas.  They were set up and tuned by folks (from Moscow?) for specific frequencies and that’s that.  I can say that from my notes it is clear that retuning them would require moving a lot of shorted transmission line sections used for phase and amplitude control.  And we have notes from a talk given to IBB personnel by a Russian engineer which state that the gain (presumably of the long version) is “40” which (if that is voltage) would be ~32 dB. I also have horizontal and vertical gain patterns for the 8 lambda and 10 lambda versions taken by a colleague from photographing a document he was shown at Orzu, but that is the extent of my actual technical data.  The drawings are so small that measuring them with a polar planimeter to obtain the gain would be subject to ambiguity.
