Re: LF: K7PO testing 8270.0

[Paul Nicholson <vlf0403@abelian.org>]

Looking at the signal at Hawley in 1 hour chunks, S/N in 278 uHz
and phase:

 23 - 00 12.0 dB  -36.1 deg
 00 - 01 16.6 dB  185.5 deg
 01 - 02 18.1 dB   99.1 deg
 02 - 03 no signal
 03 - 04 no signal
 04 - 05 no signal
 05 - 06 16.1 dB   71.4 deg
 06 - 07 16.7 dB  108.8 deg
 07 - 08 no signal
 08 - 09 no signal
 09 - 10 no signal

When the signal is there, it is very strong and a sharp line on
frequency. Then it vanishes for a few hours.  Perhaps shifted to
a frequency outside the narrow band I'm using?  Also the phase is
changing.    Those phase changes are causing the apparent spread
in the long narrow spectrum.

The pattern at Forest VA is similar but the signal is weaker so
harder to measure.

I'd guess, an intermittent GPS lock.  When it works, it works well,
a really good signal.

No sign of the signal here in Todmorden (8300 km), not much
chance until the tx is firmly locked, frequency and phase.  Then
there will be a good chance I think.
