Hi John. I use a TYT TH9800 to work with FM satellites, it has the possibility of working in duplex, according to the user manual this equipment has an internal duplexer, even so I use an external one.

I have been working with this equipment for approximately 6 years, it is a clone of the previous Yaesu FT8900R.

Do any of the current crop of Chinese FM mobile radios (TYT, Wouxun, Baofeng, etc) do 2m/70cm full duplex for the satellites?

If so, which models? I know some do dual receive, but so did the Yaesu FT7100 but it didn't do full duplex.
