Yep. I've played that audio back a dozen or so times. "6301 on Quad EMS". It was very muffled, but also matches apparatus number on Quads website. Thanks for the help sleuthing this.
My buddy in East Rochester called me today to tell me it sounded like Quad also. We then tuned to it and heard Squad 61 talking to dispatch about problems that Squad 62 was having last night (which turned out to be some issue with the button on the radio).
45129 MOMAQUAD - Mohawk Valley JFD Radio IDs (that I've seen thus far) are:

- plus 7600831 (Medic 61 - Quad)
In DSDPlus, in the DSDPlus.Radios file the radio IDs are only shown under the last talkgroup they were using. Medic 61 was definitely on 45183 as well as the MOMAQUAD talkgroup.
So Quad EMS does sound like a winner to me for 45183.
