I have a crummy antenna at home, though hope to listen for DW on a camping trip to the Eastern side of CA in a few weeks. In the meantime, I just had a listen on several online SDR's, and was excited to hear it over a wide area. In the period from about 0442 - 0446z on 9/15/2021, I heard it on Kiwi SDR's in the following locations -
Prescott Valley, AZ at Q5 with an S5 noise level.
Missoula, MT at Q5 with an S4 noise level.
Truth or Consequences, NM at Q1-Q2 with an S4 noise level (can hear whoops, but not copy telemetry).
Fort Collins, CO at Q1-Q2 with an S5 noise level (can hear whoops, but not copy telemetry).
and of course the following two -
Half Moon Bay, CA KFS at S7 with an S4 noise level (Q5 of course).
Point Reyes, CA KPH at S8 with an S4 noise level (Q5 of course).
Oh, and at 0503z, I could *just* hear the whooping under an S5 noise level from a Kiwi SDR in Booth Bay, British Columbia.
For 1 watt, this is really good!
