Scanner was on and got a little bit of what sounded like yelling on the pasp frequency in pike county . Was coming on the PSP SERT 453.0750. Who uses this frequency ?
That's UCALL 40 UHF Interop channel. As discussed in some other threads these interop channels are often used as talk around channels by various public agencies. Chances are the conversation you heard was between two school buses from the Cumberland area.
