Hi All I have only been on this reflector for a month or so. So if this was already discussed or is on the Chirp web site my apologizes.
If you have a Kenwood TH-K2 before you can program the radio using any software including Chirp you need to go to menu item number 31 (PC) and change it to "On".
When you have finished programming your TH-K2 you will then need to go to menu item 31 (PC) and turn it to "Off" otherwise your speaker mike will not function properly.
I found this out today when I was unable to program the HT using a known good cable and Slacko Puppy Linux for the os.
Searched all around the web and finally opened the radio manual which explained about menu item 31
Hope this is of some help to some other TH-K2 owner.
Thank you for your time in reading this E-Mail.
