Hi Jim,

I can only guess that a longer integration time may help.  The aerial
does not radiate well to the west though there have been QRSS60 detections
in the US.  This uses integration times of oder 10 seconds I think.

Thanks
Joe

Hello Joe,

Data from some key eclipse receivers is being processed; using data from
good receivers in Kansas and Delaware, analysts did not find your 18:00 UT
137.777 kHz signal on their first try using 1-second integration time; could
you recommend a better integration time for those two receiver locations?

Thanks!

Jim

My pleasure, Jim.
The carrier was switched off at 0935 this morning.

Transmitting a carrier on 137.777 kHz +- a few ppb 4 Amps to the
10x100m RL for the next 1.5 days or until something fails.

Unofficial EclipseMob update:

Dixon will warm up starting ~ 06:45 Pacific Time, ramping ERP to ~
1-2 kW
at 55.500 kHz and ~ 3-4 kW at 135.950 kHz by 07:30 Pacific Time,
broadcasting MSK 101010..., until one or two hours after East Coast
totality.
Dixon frequency may wander slightly.
Comparing Dixon signal to WWVB signal could be interesting.

Dixon 55.500 kHz signal field strength could be ~ 40 fT in Forest, VA

A 137 kHz signal from VO1NA, or Warren, or an LF or VLF signal from
W4DEX
might be captured and saved by a record number of receivers, and put
to good use.

There is a slight chance to observe effects via the propagation paths
from
NAU, NAA or NML to Europe. Especially NAU looks promising since the
C-flare from 2017-07-15, ~1940 utc, could be observed quite well here.

Good luck to all EclipseMob members!
