What are some oil company frequencies in Middlesex county? (Hudson, Marlboro, boston ish area..)
I'm looking for Juniper farms, Bolton Oil, and a few others.. Are they mostly Lowband? Any insight would be appreciated..
A clue to the frequency band would be the type of antenna on the trucks.
Other than that, I'd suspect that a lot of that traffic has moved to a commercial system like the ICE or Comtronics MotoTrbo trunk systems.
You can always go to the FCC Advanced License Search page and search there using company names.
