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.
