453.300 is listed as Oneida County Highway Department. I am hearing bursts of noise from time to time
but no audio. Anyone know if this frequency is correct and in use? Could the noise be a data mode?

I have that frequency tagged as Oneida NXDN, but haven't confirmed that they are using NXDN. Looking at their license WPWM474 (ONEIDA, COUNTY OF) FCC Callsign Details they have emission designator 4K00F1E which should be NXDN 6.25 and 11K2F3E which should be analog FM voice. If they are using NXDN, that would explain the data bursts you're hearing.
I've seen what appears to be (weak) narrow NXDN on the spectral display here in Phoenix ... assuming that it's coming from Oneida.
