Check your manual and see if internal chips are required. They were on
the 440. Can't speak for your radiol. Also be sure the one you have is
for Kenwood. He made various models for Yaesu and I think Icom. It is a
shame the guy building key pads now isn't interested in Kenwood. I know a
local ham who is personal friends with the guy and he isn't interested at
all in dlong Kenwood.
