I just installed CHIRP daily-20190412, and was able to program my Yaesu FT-65R with my standard list of repeaters from a CSV exported from a QYT-8900D, which was itself previously programmed with CHIRP.
Many thanks and mad props to Dan Clemmenson. I followed the developer list traffic on this with quite some interest, so I know Dan Clemmenson (and Dan Smith) put in a lot of effort to get this working. Much appreciated!
At one point last year, not too long before Dan started working on it, I signaled that I was going to dig into it....but like many before me, time and circumstance intervened, and I never fully engaged on it.
