Found a new one (to me): a dasher on 4089, 30 dashes per second, each dash about 0.4 seconds long. Anyone else log this one?
[edited to correct the dash rate].

Can you give us a bit more information? Such as, approximate UTC time, approximate area from which the signal was heard, and mode used (CW, AM, USB). Also, was "30 dashes per second" a typo? Did you mean 30 dashes per minute?

Date and time in the message subject: 4089 kHz, 7/2/19, 1647Z.
Heard on the N7DM KiwiSDR in Pahrump, NV. Mode CW, 500 Hz BW. Not heard on any adjacent SDRs.
And yes, I typoed. 30 dashes/minute, not 30 dashes/second. Dash duration was about 0.4 second.

Thanks. I'll use that info to check on that frequency from time to time using the Pahrump KiwiSDR. If I catch the signal, I'll make a recording.

Listening to KFS SDRs yesterday morning around 1500Z, conditions were such that there was VERY little atmospheric noise.
I caught a weak dasher beacon on 7088.9. AT first it was just a steady, but weak, tone and thought it was just an internally generated 'birdie'. But then it transitioned to 2 second dashes, then .75 second dashes then longer dashes again. I got a screenshot of it changing and maybe I can figure out how to post it.
The signal was weak, but occasionally would rise up out of the noise to q5 but only s1. And only heard on the KFS omni sdr, nothing heard on the NE/SW,SE antennas or any other west coast SDRs that I checked.
At any rate, I'm thinking this is the the same beacon as earlier reported, but its keying circuitry has become intermittent and generating random dash lengths and intervals.
