Of course all my Speclab instances are locked, just checked them to make sure, 424uHz was no longer locked.

Hi Eddie, Stefan,
 
this looks interesting. Accounting for your grabber timescale being an hour ahead of UT, your right dash is centered approximately at 6:30 UT. This would indeed coincide with the first dash of the blue "7" on Stefan's 6000-RDF on his second grabber.
 
However the frequency relative to the 8969.98 tick seem to be different by about 4 pixels. Stefan apparently transmitted on 8969.9815, and your dash is on 8969.9832 Hz. Assuming both were instances are samplerate locked, this disproves a possible detection.
 
Best 73 and happy Easter,

Stefan

There is a common start / finish minute on the dots in the
att.capture.HH.m3 to the best of my measurement ability, they certainly
coincide with your TX periods.
