I'm back home and things are back to normal.
Sorry if some of my "unnormal" experiments with the WSPR and the WSJT7 did upset somebody.
Being without internet made me try to communicate directly in WSPR mode, probably not a sin, but still not normal behaviour!
I will not make it a habit.
Two problems that I would like to mention:
1. When using WSPR only p/ calls like EA8/LA3JJ will not work.
Solution A: To use the home call and in addition send complete CW ID.
First days I used MixW and WSPR simultaneously, sending CW ID from MixW at higest rate in the last seconds of each timeslot.
This was a procedure that required manual timing so I looked for other means.
Solution B: To use WSPR and WSJT7 simultaneously sending DE EA8/LA3JJ in some of the WSPR Rx slots.
This required less timing effort and as an extra bonus WSJT7 does have a built in CW ID generator (at 800Hz).
I also tried using WSJT7 as a Tx robot sending all the required WSPR information which worked fine except from uploading of received messages.
