[Kenwood] Re: TM 742

[John Luthy]

And don't forget to refer your friends!!!

 My friend had sent his two AT-50's in to the local kenwwod repair
center and after repeated attempts at repair they were returned broken
and with a good sized bill for their time!!

He was about to toss the units but I convinced him to give Cliff a
try. ... the bottom line... both units repaired in record time and
still working great!!
