I checked WD9EWK's list of full duplex rigs... only one I saw listed is the TYT TH-7800. But that may mean he just hasn't checked or added the others. He likes to try out a lot of different rigs, so you might check with him.
BTW John, if you see me on 10/12m FT8 give me a call. I am down to four contacts to finish off 9BWAS-FT8 and OK on those two bands are two of them. (MO on 10m and HI on 160m are the other two.)
Back to the rigs, I picked up a Kenwood V-71 like new from a friend at a really great price... if I can just get off my duff and get it hooked up.

Good luck with the roving... 73, Kevin
