We considered doing this, but unless they used two receivers, how would 
anyone know when to shut up and when to call? Even though there is a capture 
effect, when 20 signals come up at once, usually no one wins. Now if we'd 
used the SSB receiver on the user uplink?

This whole DXpedition was on a space and operator available basis. We looked 
at sending a 817 for the transponder sats, but the space and operators 
unfamiliar with current satellites kept us to the HT and Arrow. I think it's 
still a positive that so many made QSOs considering the alternative.

Rest assured I've learned from this, and future efforts will benefit from 
those lessons. Meanwhile, I've identified the jerks among us from some of 
the really out of line negative comments directed at me and the expedition 
members ;-).
