Re: [chirp_users] Input out of range freq channels
I have used mine successfully, TX/RX, above 512 MHz.

I can listen to WWV in FM mode and hear the broadcast perfectly fine.
I can listen to the various NOAA FM weather stations in AM mode and hear the broadcast perfectly fine.
In Los Angeles I could listen to the (very near) local AM broadcast station on any frequency on some radios (including FM broadcast-only receivers).

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.
