I don't think you are understanding the point I'm making. Just because a given radio can do a given thing in a certain circumstance, doesn't mean that it's generally "usable" in those conditions, in any practical meaning of the word.
Who knows what power output you really had.
Who knows what the SWR was, and whether you are damaging the radio by transmitting out of the band that the radio was designed for. Do you think that perhaps the radio manufacturer might have mentioned that the radio is "usable" where you think it is, if they could support such an assertion?
Who knows whether it was in compliance with FCC spectral/bandwidth requirements.
These are all things that go into whether a radio is "usable", in any commercial sense.
