Watson-Watt calculation from the antenna amplitudes and phases
of the overnight signal gives 244 degrees which is reasonable
given the background noise from the south west (pulling the
apparent bearing southwards from the great circle 280 deg).
Without any calculation, I can see from the relative antenna
phases that the signal is from the west: the E/W H-field is
very obviously inverted (relative to the E-field) from its
familiar polarity on European signals.

Overnight signal peaks at 8270.0070625 Hz +/- 0.5 uHz.
Therefore about 3.6 ppb low of the DDS nominal frequency of
If I align the FT bins with that frequency, the overnight
signal becomes a sharp line -
with a respectable S/N of 13.9 dB in 46.296 uHz.
I'm now confident that this little peak in the spectrum
is 10uW from VO1NA. Distance is 3545 km.
The signal amounts to about 2.6 electrons on the E-field probe.
How's that for a signal report Joe?
Also getting a bit of a signal visible at Forest, Virginia.
Not a very significant peak but it has the same offset.
Only visible on the overnight signal, nothing yet on the
daytime. Distance to Forest is 2442 km so that's very good
for a land path.
Forest is E-field only so no rejection of the South American
