Please file a bug with detail to reproduce the problem and an image file 
on http://chirp.danplanet.com/projects/chirp/issues/new I'll take care 
of this next monday.

You are right, this is the way ft857 and 897 work.
During development I discovered that setting those bits in invalid 
combination is safe, I mean it does not brick the radio in any way, 
maybe they are ignored but they are harmless. This is why I decided not 
to limit user actions here.
If you have indication of any harmful effect please let me know.

Tnx
