It does cover 80 through 10 m.
I don't have an antenna that is designed for 80 m, guess that's why I forgot 
the amp will work there.
I can get the R7 to tune up on 80 but haven't tried making any contacts 
there.
I'm afraid to put 100 watts through the R7 on that band let alone any power.
I don't want to hurt anything.
Thanks, and 7 3.
