Moved to Amateur Forum....
I've been using a program called Link700 for a couple of years now....I don't think the guy is updating it, but it does allow you to edit/cut/paste/move frequencies for the TH-D7, TM-D700 , TM-G707, TH-F6/7, TS-480 and TS-2000. And - it allows you to work on the different radios SIMULTANEOUSLY and cut/paste between different radios. It has a few nuances...but it's basically not a bad program. It works.
Looks like he's trying to update it for the D-710.
Anyway, the link:
