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

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. -- Paul Nicholson --
