CHIRP

Currently it is impossible to copy a memory channel from one radio to another when the channel in the first radio uses a setting that doesn't exist in the second radio.

Example: UV-5R has a "duplex off" option to disable transmitting but KG-UV8D does not. Trying to copy a channel using this option results in an error message and the channel can not be copied at all (even though the frequency, name, tone, etc settings should be able to transfer). This is probably not what anyone ever wants. A more sensible behavior would be to revert that setting to the default value and copy everything else if possible, or ask the user what value to use on the new radio (and remember that translation when copying a group of channels all at once).

The second option would also make a different, less severe, manifestation of the bug easier to resolve: names for power levels are not standardized at all between models. One of my radios has "High" and "Low", another has "H" and "L", yet another has "Hi", "Mid1", "Mid2", and "Low." In this case the user could to choose to convert all "H" channels to "Mid1" and all "L" channels to "Lo" without manually changing everything later.
