I have the 7999.2 version of this dasher here, fading in and out. No sign off its twin on 4097.2 right now. Maybe that is a name "twin dashers"... that is.... unless there are more of them lurking out there tied to these two. 19:45 UTC 15 JAN 2021

7992.2 very strong here on the longwire and Airspy HF+ Discovery, 4097.22 is also there but very weak right at the noise floor fading on the vertical and the Airspy HF+ (I run them at the same time on two different computers). They look the same signal wise comparing between either SDR or antenna. Right now what I am hearing and seeing is they are alternating, one keying when the other is off and vis versa. Could be just latency between the two SDRs and computers but it seems real consistent with no overlap between the two. 00:05 UTC 16 JAN 2021

Interesting logs, Ron. I'll have to give a listen with some Kiwi's around 0000z tonight.

Thanks, I will be interested in what you hear. This was the first time I could ever hear both of them at the same time. Got tied up this evening and didn't get to listen earlier. I have 4097.22 now weak and fading but there, no joy on 7992.2. 05:30 UTC 17 JAN 2021

Well, could hear 4097 via KFS very strong here, but nothing at 799x. WiIll try again later though as there's some Peskies up there now.

7999.2 fairly strong. No joy on 4097.22 right now. 20:58 UTC 22 JAN 2021

4097.22 just fading in here, while also watching 7999.22 on the other SDR it faded up out of the noise and came up very strong. I can see both of them now and they are alternating the dashers one on when the other is off and vs versa. 01:00 UTC 28 JAN 2021

Instead of the dasher I am hearing a strong, fast ditter on 4097.28

I'm wondering if the creator of the dasher decided to make things more lively by changing from slow dashes to the fast dits? I am realy appreciating the revitalized 4 MHz beacon spectrum.

It's very strong right now in this capture from KFS

Left to right is the "evolved" Desert Whooper which is now about 3 months old. Next is the slow dasher that may have been the Inyo WHooper in the past and then to the right is the fast ditter at 4097.29-ish

I'm thinking this is a permanent change from slow dash to fast ditter.

It's again very strong right now in this capture from KFS, ditting away on the right of the picture.

Left to right is the "evolved" Desert Whooper which is sending telemetry. The five slow whoops are a good visual and audible cue. Next is the slow dasher with it's tell-tale hook/rise in frequency

I note a slow dasher - rather weak most of the time - per above on about 4097.22 or .23; a very fast ditting beacon stronger on 4097.27 or so, and "Coxie" slow (OTA a very long-time now) dasher around 4095.9 and higher (it drifts); and the telemetry-whooper below all of the other noted beacons in its frequency. Note the telementery-whooper has the "opposite whoop" than the former Inyo Whooper (solar-only) did...

I don't note the slow dasher around 4097.22 or .23 on the KFS/SE receiver in listening over the past couple of days, however, but I heard it this morning very close to the fast-ditter around 1100 PT/19z though far weaker.

HexY2K ~6700.5 and ~6626.3 Rainy noted strong here at times mid-day, including today...

The slow dasher was originally very strong into the KFS kiwis so something changed/broke if a weak signal has been heard.

Note that the new-ish “DW” whooper not only has a whoop that’s opposite to the defunct whooper but the defunct whooper never had a Morse ID,  four different Morse telemetry streams or run 24/7......

It's again very strong right now in this capture from KFS, ditting away on the right of the picture.

These, the 2 second dasher and the fast ditter, do not appear to be the same signal.  Instead it looks like the fast ditter has shown up on very clsoe to the same frequency as the dasher, and the ditter is typically the stronger signal.

Prior to today I thought that because the propagation of the fast ditter appears different from the 2 second dasher.  The dasher was more condition impacted, I mean when conditions were very good (based on multiple signals) so was the dasher signal, but when conditions were very bad so was the dasher.  I might go for days not seeing / hearing it, and then watch it slowly fade up as conditions got better.

The fast ditter has been more consistent in level, almost always being heard, day or night, at my location.

Also, I could sometimes null the ditter with a loop and start to hear what I thought was the dasher under it.

But today I am more sure.  It looks like the dasher has shifted down in frequency, more near 4096.1 kHz, and as I type this I can hear both the dasher and the fast ditter.  Also, it appear the 7997.2 dasher, possibly synchronized to the 4096.2 dasher, appears to have shifted down to about 7997.0.

Mr. Token  :-)

Thanks for the wealth of details. I'll update our master beacon list!
