They're still very active here in NE PA on their 37 mHz channels. However, I know for certain they have some other channels. Reason is that I was parked near a PPL truck with all of the workers outside on poles, etc. They had the truck radio up very loud. I recognized the dispatcher's voice as the same I always hear on 37 mHz. But the scanner in my car was picking up nada. So I went into search mode up/down around 37 mHz, 450-460 mHz, and some 800 mHz. Still nothing. Unfortunately, I did not have my Close Call capable scanner with me, just my BCT-8 in the car.
