Why is every "what to buy thread" turning into "is it legal." Facemasks?
Because those of us who are hams interested in actually being hams don't want the ham radio exemption closed by the FCC.
Break the rules all you want just don't drag amateur radio through the mud by using the MARS/CAP modification (MARS requires an additional authority to use your station and CAP no longer recognizes non-NTIA compliant radios) or the 97.403 and 97.405 "any means possible" exemptions when the intent is clearly neither MARS nor SHTF emergency use. Operating a modified ham radio (meaning a radio that has only been tested to Part 15 scanning receiver rules, if any at all) on GMRS if you hold a ham license violates both Part 97 and Part 95 rules.
Sorry it upsets you but I doubt you'd stand by if someone decided to tell people on a public forum where and how to drive on routes closed to motorized users. Whether any of this is a crime that's actively enforced is aside the point. Publicly on the RS forum is not the place to encourage it, that's what prompts me to comment.
