My 83 was deaf in the airband until I switched from the stock antenna to a
Diamond RH77CA.

The Diamond RH77CA is an excellent scanner antenna, much better than the
short stock duckie of the Pro-83. I just picked up the RH77CA for my 83 and
lo and behold, it "hears" much better now on all frequencies. I got the
antenna at Universal Radio. I would suggest that Pred02 pick up one of these
as it will probably make a noticeable difference in reception.
