I, too, have not heard anything from Cleveland State University PD for some time. They are on a trunked system but no activity there. They did just move into new facilities on campus.
I am now hearing CSU Police at 463.7625, I don't detect any PL/DPL. It does sound like a UHF trunked system, I will hear police most of the time, then parking, housekeeping occasionally.
The database has been changed to reflect a DPL of 152 for certain CSU conventional frequencies, such as 452.05 and a few simplex channels.
The frequency you mentioned [ 463.7625 ] is part of the CSU LTR system. That is a trunked system. You can program the LTR frequencies in conventionally if you don't have the capability of programming an LTR system into your scanner, but it does not transmit a PL tone and you will not see the talkgroups displayed on your scanner [although you'll hear them]. For those who can program an LTR system into your scanner, you are probably better off doing that since you will then see the various talkgroups.
