MON VALLEY POLICE, FIRE, EMS ONLINE SCANNER ON RADIOREFERENCE.COM Ever wonder just what the hell is going on in Monongahela? Well this link is the next best thing to having your own scanner. You can monitor Mon Valley public safety live radio communication by local Police, Fire, and EMS services. Scroll down and you will find links to four online feeds. I use the first one but one of the others may suit your needs better. If you wish to listen to all four feeds simultaneously then click on the “Launch The County Web Player” link at the upper right hand side of the page next to the map of Pennsylvania. I just let it run in the background while surfing the web. Happy snooping!
