More FAKE ham radio. But if that is what floats your boat (so to say) go for it.

I don't think AA7JV has to worry about things being "expensive" when he lives in a 23 million dollar home. Don't believe me?

Don't get me wrong I'm all for capitalism but operating HF from a boat via a 900MHz link is even one step below operating HF via Internet remote. I guess that is how the ultra rich go on DXpeditions. Hopefully he will have a lot of good DXing story's for the boys at the Miami yacht club.

When I first read about the RIB concept I admit I was skeptical. Still am. I'd rather see old fashioned solo, small team and mega DXpeditions actually operate from the physical DX location but - in those rare places where that may never be allowed again?
Maybe there's more to consider. Fair game for disagreement and debate.
As to wealth. I am certain that him and I are at totally opposite extremes financially speaking. I won't hold it against him. Ha! If I had that sorta money I'd probably be doing more cool stuff with radio (among other things) too.
I have had two CW QSO's with him, one email exchange and he did upload to LOTW which was unexpected. All of his communications have been civil, courteous and friendly. I do hope do work him again on CW/MM as they voyage across the South Pacific.
