Anyone know what system/freq SW&B uses? Wanted to see if I could monitor comms related to the pump system. Just curious what that looks like.

They are licensed for a trunked system (WROE402) using the following frequencies:
856.7875
856.8125
857.7875
857.8125
858.7875
858.8125
859.7875
859.8125
860.7875
860.8125
From the emissions codes, it may be encrypted. There are 2 talkgroups on the LWIN statewide trunked system.

26550	67b6	D	SWBNO Disp 1	Sewerage and Water Board of New Orleans Dispatch 1	Utilities

Thanks! Just getting started figuring RF out with my HackRF and an RTL-SDR. Appreciate the help!

As far as I can tell, those frequencies are an LTR type system and only 1 or 2 frequencies are regularly used. Regular monitoring is normal installs of water meters, main line leaks, etc.. Would have to monitor during storms to see what else is on it.
