At the April 2018 business meeting, Bob, K1KVV mentioned that the local NOAA Weather Radio broadcasts (162 MHz) were are having technical difficulties since the move of the National Weather Service Forecast Office from Taunton to Norton. Bob mentioned he had a list of frequencies for local AM aircraft band weather observation station frequencies, including the one at the New Bedford Airport.
The frequency list is available online at the Federal Aviation Administration (FAA)’s Air Traffic section. There, you can search down to the state level with an interactive map and listing of frequencies. You can also search by airport ID and the results will also inform you of the weather station type (ASOS/AWOS).
