Starting 2 days ago DW has exhibited some ragged keying. Signal strength seems normal when keyed up but some "whoops" and Morse characters go missing. It could be the result of the constant heat out there or an after effect of the last time it went off the air. The keying problem does not seem to vary directly with the reported temperature changes. Battery voltages seem normal.

EDIT

This report was based on the KFS SE kiwi SDR but I should double check other SDRs for compparison

It seems that the KFS SDRs may be having more issues than I recently reported to the owner/operators

(see   https://forum.kiwisdr.com/index.php?p=/discussion/2605/possible-bug-with-public-facing-gui-fixed-in-v1-523 )

Now that DW is coming in strong this evening it sounds just fine. However, I found this interesting issue reported by our very own forum owner (Smolinski) and it makes me wonder if that is what made DW sound glitchy on the KFS SE kiwi.

That sounds like a very plausible explanation for the glitchy reception of DW Jim. DW is quite strong in Southern Utah and, as you observed, sounds fine. At about 1130pm MDT on 6/19/2922 (0530z on 6/20/2022) DW was 13.0V, otmp 76, itmp 86, pv = 1.

Receiver for the above was my plucky little Belka-DX with the telescopic whip.

I've been trying to kick and ban these Chinese bots when they appear on the KiwiSDRs, but unfortunately they frequently change IP addresses to avoid the bans, so it is like playing Whack A Mole.

Good reception of the Desert Whooper and the Slider on the northern CA KiwSDR. I don't think I'll be getting up early enough for local reception of 4 MHz beacons for some time  :)

Last night I rolled into Saint George, Utah around 11 PM and tuned in DW on the truck's Yaesu FT-857D and heard it faintly but clearly. Since the ATAS-120 antenna isn't made to go below 7 MHz I tune it to 8191 KHz and hope enough of the 4095.65 signal gets through. Will have to look at the 120 antenna with a network analyzer some day.

Back home tonight and DW is so strong I can easily hear it on the NRD-525 set to Narrow filter

Jum[img in a bit late, but I just started looking for Beacons outsides 33 m. The DW signal is very readable here in Northern California after dark, S3  S5, equal to the noise. Antenna is an 80 ft random wire with transformer isolated feeder back to various radios. The higher frequency "desert slider", 4108 kHz is also easy copy, similar strenghts.
