I got a surprise gift for Christmas a Kenwood tmv7a. I understand that there is a firmware revision to permit me to upgrade it to a tmv71a. I have the touchtone mic with it and apparently you can't program it from that mic but I'm not sure. The synthesizer in it is the vgs1. It seems to have a much better receiver in it than my ic2100H which if it will fit can go in the car since my xyl tina is also a ham. 73- pat kk3f
