Bob,
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).

FYI,
If you leave near some Military locations in the USA You will have 50 watt PEP limitation.
The satellite mode of 611 ERP only applies to 435-438mc and not the eme segment of 432
If you are out side of a military zone, then normal power rules apply.
§97.313 Transmitter power standards. (f) No station may transmit with a transmitter power exceeding 50 W PEP on the UHF 70 cm band from an area specified in footnote US7 to §2.106 of the FCC Rules, unless expressly authorized by the FCC after mutual agreement, on a case-by-case basis, between the District Director of the applicable field facility and the military area frequency coordinator at the applicable military base. An Earth station or telecommand station, however, may transmit on the 435-438 MHz segment with a maximum of 611 W effective radiated power (1 kW equivalent isotropically radiated power) without the authorization otherwise required. The transmitting antenna elevation angle between the lower half-power (-3 dB relative to the peak or antenna bore sight) point and the horizon must always be greater than 10°.
And from US7 (e) In the State of Massachusetts within a 160-kilometer (100 mile) radius around locations at Otis Air Force Base, Massachusetts (latitude 41°45' North, longitude 70°32' West);
