Thanks. I’m not a “trouble” person. I follow the rules. You have no idea why I asked. And I have no plans to do a physical mod and damage my radio.The MARS/CAP mods are just an excuse for opening up the bands on the radio. There is no use for the CAP mods today because CAP uses narrowband and is, at least partly, P25. I doubt if there is any MARS activity on VHF/UHF. Opening up ham radios for out of band use is poor practice. A friend of mine started doing an ARES net on the Southern Pacific road frequency once. Not cool. They probably didn't hear him because he didn't have the PL set. Nevertheless, you can get into trouble very fast.
While not P25 capable, the FT-60 has narrowband capability (wide/narrow selectable). Narrow mode also narrows the receiver, not just narrow the tx deviation.The MARS/CAP mods are just an excuse for opening up the bands on the radio.

Not exactly, Part 97 is very forgiving in the respect that you are allowed to modify the radio and still be Part compliant. Heck, you can build your own radio and as long as it meets the parameters of Part 97 it is compliant without ever having had the FCC look at it. It is the transmitting on those frequencies that is outside of type acceptance.Any modification, or " opening up the bands on the radio", violates the FCC Type acceptance.
Thank you.In the interest of actually answering the OP's question: I never ran across a way to open it up using software. I had done the hardware mod.
The VX-1R was able to be opened up through a very elaborate series of front panel keypresses, which involved settings and frequency changes and was harder than you'd think given there is no numeric keypad.
