They would say . you know the rules and you have to follow the rules The thing is . who has to make the technical decision if ros is spread spectrum so forbidden in us (answer: the user)
Next thing is . is ros really ss??? What I know about ss is sender and receiver are spreading the data very wide Factor 10 is minimum to say it is ss but normally far more is used In ros the spreading factor is very small . and so it looks more like mfsk on the air For me as I am no professional in data transmissions it looks like it is afsk (like many other soundcard modes) Does the ham need to have the knowledge how the tones are calculated??? If the tones are spread spectrum or not?? What about digital sstv modes?? How can a user know if the used bandwith is (much) more as needed?? Any fec mode uses more bw or more time as needed for a non fec transmission Why not just modify the rules a bit Frequency hopping or wide spread spectrum only above 220 And the narrowband ss modes like ros and all other modes (incl. chip, Olivia and similar) can be used on shortwave if the bw is lower as 3kc (like her in dl)...surely with sdr wider ss modes could be used . but not allowed Synced frequency hopping with sdr would also be possible . but not allowed Just say . any mode bw <3kc ..(exceptions possible like >0.5kc on 30m or historical am transmissions) That would be easy All modes should be free available to anybody (so fcc cia mi6 etc can download the soft and use it too) Modes where you need special hardware are only allowed if the developer also gives a free software solution (for receive only) (hello d-star, hello scs) ..for monitoring Think about > changing your rules is easier as trying to tel ros is not ss .. Cause next new mode will come soon . and story returns . so change your laws in us 73 Sigi Ps: I am glad that I live not in the land of freedom hi hi :-)
