A good question since they will be using SSB, initially. I do not
operate eme on 432+ but I believe that normal calling is done on
2-1/2 minute sequences. I suspect that will not be done with Arecibo
(but they should say what their operating protocol will be).
Normal eme protocol goes like this:
CQ de KP4AO calls for 2.5 minutes
KP4AO de KL7UW means KL7UW copied KP4AO call sign (not calling in the
blind); calls for 2.5 minutes
KL7UW de KP4AO signal report (May be RST or OOO); also means Arecibo
copied both KP4AO and KL7UW's call sign; gives report for 2.5 minutes
KP4AO de KL7UW roger your report (RO) and/or RST; for 2.5 minutes
KL7UW de KP4AO RRR means I copied your report; for 2.5 minutes
KP4AO de KL7UW 73 and SK; end of successful contact; for 2.5 minutes
total time 15-minutes
So with 2:45 hours of operation 11 QSO's could be made; so I do not
expect the usual 2.5 minute time sequence.
That is usual for CW and digital eme, but I do not know what is
likely to ensue with the expected pile up on SSB. But for proper eme
both calls must be given and confirmed (unlike HF were only one call
is stated and the other station, assumed).
