Bob, Mike and Joe,

Am I inferring correctly that Bob's signal became visible at about 0600 UTC
in Newfoundland and Hertfordshire, remained visible in Hertfordshire until
about 0615 UTC, and remained visible in Newfoundland until about 0630 UTC?

Prior to realizing that Mike and Joe are about 3.5 hours apart, I wondered
if the emergence of Bob's signal was related to refractive focusing at the
day/night terminator.

If the clocks on Mike and Joe's spectrograms are both in UTC, the terminator
idea is probably wrong.

If the clocks on Mike and Joe's spectrograms are both in local time, I
suppose the terminator idea could have some merit.

Any thoughts or corrections on the above?

Compliments to all on these confirmations and the work that went into them. 

Regards,

Jim

Bob,

Good to have the reception confirmed. I have been monitoring overnight for
several days now and that's the first time I have seen anything useful.
Let's hope conditions improve shortly.

As someone who operated on the old UK 73kHz band, I know how much harder it
is to get out at that frequency than 136kHz, so well done and thanks for
opportunity to monitor for something really interesting.

73 de Mike, G3XDV.
