I don't have the latest version, but when I loaded the software, and
selected the radio and comport settings, it took off like a bird, and
everything worked as advertized.
Everything except the cw transmit.
Maybe I missed something, of a menu setting in the 590 needs adjustment?
Its an amazingly full featured program.
Jim put a lot of thought and creativity in to it.
