To my knowledge WM is not using radios But EDCO,EDI Disposal and Republic use radios.
Most voice traffic is in spanish
1-19-030 I believe is EDCO as well this talkgroup could be for EDCO trash/recycles
1-11-040 is EDCO this could be used for green waste pick up (green bins)
They might have some UHF also which might be for yard dump operations
463.850 PL 82.5
463.400 PL 82.5
936.125 LTR frequency This could be something also
