Download the last daily build and install it. 
Chirp has an autodetect setting for Kenwood so try that
first. If it doesn't work see if the TM-271 / TM-281. I don't
have the latest build because it works ok with the radios 
I use it for. You can also wait around here to see if one of
the programmers who write for Chirp to tell you exactly 
if the radio is supported.
