Hi & welcome to the RR forums:
If you're aiming to monitor ICORRS, you'll need a handheld that can monitor P25 Phase-II. Note: All law enforcement is encrypted in Butler County, as is every talkgroup here identified as mode "DE" or "TE". It appears as if simulcast distortion could be a factor while monitoring the Butler County sites so my recommendation would be the Uniden SDS100 to best mitigate this.
I can say the SDS100 works the HP436HP can also work depending on where you are. In fact, I use to use that for the feed for butler county until I stop providing it. I have also used a Home Patrol 2. I used all three. But the only one that leaves the house is the SDS100.
