I'm looking for some info on the mars mod on a kenwood TM-V71A ... Just want the info in case things ever gets bad. working on my licence right now and don't want to buy a radio that I don't have the info for the mars mod.
This may be what you're looking for. I haven't read it, though.
By the way, I'm not responsible if you brick your radio. I know I've lost my fair share of magic smoke when playing with things I shouldn't.
