Just recently got back into using Chirp for my radios, after a few months away.
Soon as I installed the daily (5-7 days ago), I was THRILLED to find that it'd finally talk to my tm-v71a correctly.
Just today, however, after having updated to the 2012-12-24, it fails to receive a response from radio, again, either via auto-detect or manual entry of tm-v71.
