FT8 station selection


 

A brand new newb on the R1CBU software. I was successful in downloading the v.29 software and loading it on the x6100. Using CQ I have made some contacts. However I seem to be befuddled with how to trigger on a contact with a station calling CQ. It seems like when I can trigger a particular station calling CQ I am a cycle or 2 behind answering. Am I doing something incorrect?
Additionally fwiw I uploaded the adi file on the sd card from a successful QSO and while eQSL said the upload was successful it did not appear in my outbox plus got a message the "logger 1601" was not update in eQSL and to advise the webmaster.
Excuse my "2 issues" i one submission.

FT8 app on X6100 can start transmit with not more than 1 (or 1.5) seconds after 15 seconds time slot started otherwise generating and transmitting message might exceed slot.
Also FT8 decoding support "incremental" decoding - some strong stations messages might be decoded 1-2 seconds before ending time slot. In theory - you have about 2-3 seconds to select CQ station and press MFK to start calling it without 2-slots delay. Otherwise app will wait for the next time slot, when chosen station will listen (30 seconds).
