Thanks for the additional info and comments, Delta.
Although I have logged 36832 in use before, on this occasion the comms were between two separate mobile units - F1 and F2 - who were trying to find their way to the scene from I-77 via Hwy 97.
The talkgroup is digital.
For mobile units, the Lancaster site seems to do quite well to the southwest, as I occasionally will hear a Fairfield County SCHP unit on the interstate off the site ... even from below Hwy 34. Unfortunately, the Chester site is not consistant-enough to monitor here.
