That would mean if you would implement ros or similar in a multimode soft like multipsk or dm780 you would not be allowed to use it (the whole soft) in us ??? I think if only a part of the soft is forbidden to use (on transmit) all other modes can be used
If for instance rtty was forbidden in germany but no other mode I can use all other modes in a given software So if in us ros hf is forbidden (but not ros mf) you could use it in us . right?? Just my understanding of laws ,, but I may be wrong Sigi
