The DW Whooper changed it's "whoop".  ;D

It now sweeps low to high with the very first whoop going from 4095.65 to 4096.35 and the next 21 whoops from 4095.65 to 4096.25 KHz. The sweep is a bit more linear and no longer has that "fishhook" look.


The CW ID of "DW" is still at the low end at 4095.65

Yeah, I noticed that.  I grabbed some SDR recordings of it right after it changed and will do a new video sometime this week.  I also noticed the ID has a small whoop on the entirety of the letter D that was not present before.

DW still sweeps low to high with the very first whoop going from 4095.65 to 4096.20 and the next 21 whoops from 4095.65 to 4096.1 KHz. The CW ID of "DW" is still at the low end at 4095.65 but no longer has that chirp on the first dash.

A little while ago the transmit format changed again. Same whoop pattern in terms of frequency but 11 total whoops. At the moment instead of sending DW in Morse code it is sending 12.7

Coming in S3 on the KFS Kiwi SE radio. The format of the beacon is now back as I reported yesterday. It was interesting that it sent the numbers "12.7" for a little while.

DW still sweeps low to high with the very first whoop going from 4095.65 to 4096.20 and the next 21 whoops from 4095.65 to 4096.1 KHz. The CW ID of "DW" is still at the low end at 4095.65 but no longer has that chirp on the first dash.

See Token's latest video for a really nice video illustrating the signal.  https://youtu.be/Eh8Hlkvr__I

I wonder if the time when it was sending 12.7 was at the end of a fully sunny day?

The format is a bit different today. Five cycles of "DW" and 32 whoops.  Then "DATA" sent 5 times in a row (no whoops), then "12.8" or "12.7" sent. About 4 minutes for a complete cycle

DW is still following this latest format. I've copied a peak of 13.0 (assuming volts) at times during the day today.

Since it went to this new format it has been very weak here at the house.  I can, sometimes, see it and hear it, but just right at and in and out of the noise floor.

Roughly the same format but with interesting changes: 5 sets of ID & whoops, "DATA" sent 5 times in a row then one set of numbers/telemetry (?)  The overall cycle is still about 4 minutes with 33 seconds between "DW" in the set of 5.

Each whoop still sweeps from low to high
At times, two different whoop rates heard between CW IDs.
The "Fast" whoop is about 31 whoops between CW IDs and "Slow" is 18 whoops; not quite 2:1
The first whoop is now exactly the same duration as all of them, about a 200 Hz upward sweep
The CW ID of "DW" is still at the low end of the signal, about 4095.65
"Voltage" readout/numbers/telemetry that varies between 12.7 and 13.0

Good signal on the KFS SE Kiwi right now. Fast whoop is in play. Telemetry says 13.1

S3 to S5 on the KFS SE Kiwi

Switched from slow to fast whoop about 6:50 AM
Whoops all have the same duration.
Time between DW IDs is about 63 seconds with about 63 whoops
After 5 IDs it sends "DATA" twice
Then it sent 12.7 VLTS and 0.0 TMP
Overall a cycle is about 7 minutes

Finally heard it here at the home QTH for the first time this morning just after 1300 utc.  Did not stick around long.  Only heard the whoops and a couple of DW's.
