If we want the most "bang for the buck", it would be something that supports the most QSOs per watt of solar power. Since most hams have computers, something that supports half a dozen PSK31 sessions would suffice. Given the new open-source voice codec you could also make something that supports multiple digital voice QSOs with less power than now required for analog FM or SSB.

Perhaps we should define, "most capable equipment." And we also need to define "bang for the buck."
