hey another thing im not sure about . i pick up ithaca line on a different frequency but my scanner is haning out on 152.0975. is that how there sapose to do because its the strongest signal ? if i go into ithaca terratory will the scanner lock on to there site if it has a stronger signal
When you have more than one Control Channel programmed, the radio will lock on the FIRST active CC frequency it finds. It doesn't do anything smart to determine which of many frequencies may be the strongest.
As you travel, you 'may' travel out of the area of coverage for that site. Once the radio no longer receives that frequency, it will resume scanning the programmed CC frequencies until it finds an active one. Then it will stay on that site until the signal is lost again.
(On the BCD996T for example, you could also turn the dial to cause it to scan the other frequencies.)
As far as the D.E.C. frequencies go, it doesn't surprise me that you would hear NYSEG on them. Especially if you have the radio in the truck with you. You would very easily get into the front end of the radio. I'm not aware of any NY DEC changes.

Edit: I forgot to mention that I believe 152.0975 MHz is NYSEG Site 0105. I can receive that one when I'm in the Owego area.

You can go to this Wikipedia site for some basic information about how a trunking system works:
Trunked radio system
The controller sends a digital signal to all radios monitoring that talkgroup, instructing the radios to automatically switch to the frequency indicated by the system to monitor the transmission. After the user is done speaking, the users' radios return to monitoring the control channel for additional transmissions.
