Got this quote from Haledon's July 12, 2018 council minutes:
"Repeater radio at William Patterson University for OEM will be used now by Police Department, In case of an emergency OEM will use it."
So I'd check Haledon's listed OEM frequency of 154.995 PL 107.2 first. Now I don't know if the OEM radio mentioned in the quote refers to Haledon's OEM radio or OEM for the campus so if you have an OEM frequency for WPU I'd check that too.
Also, Haledon accepted a donation of 20 XTS-1500 radios from WPU at their October 25, 2018 council meeting.
