[amsat-bb] Best HT for satellite operation?

You are simply wrong. The Kenwood TH-D72, D7, D7(G) as well as the Yaesu
FT-470 and FT-530 all are excellent full-duplex HTs with no desense.

It appears you are suggesting that people operate half-duplex. That can
work somewhat, but is definitely not something I would ever recommend.
