Doesn't an ID originating on the 70-cm link end up being
transmitted on *both* frequencies? Am I missing something?

Not on the 70-cm side coming OUT of the mobile radio. That's why you
come in on the 2 meter input.

No matter which way you slice it, when you give an ID
it goes out on BOTH bands concurrently. Still don't see
that there is even any issue here?
