I have 155.220 in the scanner as CSQ so I could heard Life Guard out of Cedar Rapids but they moved to Linn ECC and have not heard anything at all from anyone, I checked and didn't have the channel set to digital or have attenuation on.
I was just checking Whiteside Co in the database and they have 153.860 listed as Ambulance Dispatch not sure this is just CGH's or what. No tone is listed.
Below is from my records:
CGH Hospital Medical Center, Sterling IL
N 41,48,6.1 - W 89,41,49.2
