I'm not aware of any particular shortcomings of the '780. For what it's
worth, the two I own are pretty long in the tooth and both are still
working well. If it has been a 'long time' since last used, is it
possible that something in the shack (or nearby) is affecting the '780
front end. Move the '780 to another location (far away) to see if there
is any improvement.

If you have come here to find out about the Uniden BC-780 you have come to the right place! In fact the discussion of the BC-780 is the only acceptable topic on this list. Please. I hope this is clear to all group members.<BR>
