There are rumors that the Yaesu FT817nd will be replaced by the Yaesu FT818 at the end of March. Not much seems to be changed. Only one watt more: 6 watts. (I don't mind)
Very interesting is the 60 m band. My FT817 is still doing a good job for 10 years now. Maybe I will buy the FT818. Have to wait for more additional information. Wait and see if it is worth the money.
