Could also be interference from Washington County's EMS Repeater output 158.760. There are towers on both Willard and Colfax, depending on when you were listening, Radio Repair was working on the Colfax tower yesterday including the Local Govt station. Saratoga 911 can be audible on Washington County mobile without the RX PL programmed and on Minitors while in Saratoga.
There are several cases of poor coordination of frequencies.
158.760/158.775 Washington County Local Govt (EMS)/Saratoga 911
154.145/154.160/154.175 Essex County Alert/Washington County Alert/Warren County Alert
It is not uncommon (not so much now with both systems being updated) that Warren and Washington Counties would set off pagers from the other county due to the proximity of the alert frequencies.
It will continue to get worse with the narrow frequencies. When Bethlehem put in their new radio system in with narrow frequencies, their police repeater 154.1675 was load and clear at the Washington County Communications Center on the Fire Alert station 154.160, until the stations were replaced and PL'd.
