There are far too many questions here that need answers - first off, where is your grandmother? (county/state is fine).
What system are you trying to hear? Go up to the top left, select DATABASES, then FREQUENCY DATABASE, then use the various pulldowns and maps to get to what you want.
How did you program it? By hand or using software? Which package (if you used software)?
The object oriented scanners - of which the 1065 is one - isn't quite a plug and play like old scanners were. There are any number of possibilities here that might be causing issues, and even being too far away from what you are trying to hear is a definite possibility.
Too many questions, not enough answers...Mike
