I was thinking those 453's were part of the old radio system. The trunk system went into service around 2002 or 2003 (correct me if I'm wrong). I remember 2002 was about the time the older buses got the new MDTs and radio system placed in them. SEPTA uses the 131.8 PL on the inputs for the PD, MoW, BSL, and MFL repeaters along with the 504.1375 frequency used in simplex mode for yard operations on the MFL.
