Ok, I created a FreeScan programming file with just the NYSEG control channels and put it into a ZIP file for unloading here.
Download it and unzip the .996 file. (48_ALL_NYSEG_CCs.996)
The file has ONLY the NYSEG system so you can program that into your BCD996XT without disturbing the rest of your current programming.
Two things to keep in mind.
1. The file I created has System Quick Key 48 assigned to it. If you already are using that SQK, you'll need to open the file in FreeScan and change it to a quick key that you aren't using.
2. If you program it using the settings in the screen shot below, FreeScan will just add that system to your scanner without changing or erasing any other settings.
Assuming it's programmed into your BCD996XT successfully, have the radio scan or search only that system.
Press HOLD and rotate the tuning knob to the first frequency in the file. (151.730 mHz)
Then slowly rotate the tuning knob one step at a time. Let it sit on each frequency for a few seconds.
You 'should' eventually see a signal meter indication on the scanner.
At that time, if it's a NYSEG control channel, it will display the System ID and Site similar to the following.
SID:0269H-0109
The last four digits will be the site number. (0109 in the case above)
Repeat that for each frequency in the file. (There may be more than one site that you can receive.)
Once you've identified the active control channels, you can create a System File for each site.
You can PM me if you have additional questions.
Good luck,
Rich
