Little field trip today to Monmouth Park Racing in Oceanport, this is what I came up with: (1) 152.385 DPL 023 - this was referred to as " Dispatch "; they use two operations channels (2) 159.835 DPL 152 and (3) 151.585 DPL 032. The first aid room was on this channel. I noticed a maintenance person with a UHF antenna, but no UHF transmissions were detected. It is unknown whether that was due to another frequency or a radio with the wrong antenna. If anyone wants to submit them, feel free.
