Been looking myself, not sure if they bought First Student but the 502.9125 is dead, nothing heard anymore. All of ASD schools are Analog systems so they would of needed to supply schools with radios.
Hopefully can keep searching with school starting back up tomorrow.

Northwestern Lehigh VHF Digital
Northern Lehigh - UHF digital (school ops)
Whitehall Coplay - uhf digital
Catasauqua School- VHF digital
