It appears that WestCom Fire Dispatch (Forest Park, Oak Park and River Forest FDs) is currently transmitting on 159.120, which was their legacy VHF dispatch frequency. I was under the impression that this freq went silent after they moved their dispatch traffic to STARCOM21 TG 34417.
For those unable to listen over the air, transmission can be found here OpenMHz .
