Shouldn't the restriction be placed on the use of the shared resource (the air)? That is, modifying the transceiver should be fine on its own. What I'm trying to point out is that your comment seems to suggest restricting users from making any (all) modifications, even if they wouldn't affect anyone but themselves, because they might make a modification would affect others. I think one should be allowed to make any modifications as long as they're made responsible for how those modifications affect others. And even if a modification potentially (not through every use) negatively affects others, they should only face consequences when the use actually affected others or went against regulations of the shared resource (the air).
