Sure, or maybe that ebkey program should have an option
to control the key through another gpio pin?

I've not tried that but I don't see why ebnaut-rx wont
take a large T offset. You'd have to manually loop over
multiple messages in a file, putting in the appropriate
T offset each time and renaming the log file after each
message is completed.

I couldn't see anything in the cross-correlations of the
non-decoded message slots.

Checked all the decodes and the correlation peaks were all
within 60mS. About right for ntpd + keyer latency + propagation
delay.    That's the clock sorted then.

I also checked the absolute phase of the messages and found
some large shifts from one message to another.
