Not a problem...
Just chick on this link.... Mercer County Sheriff, Police, Fire, EMS, and EMA Live Scanner Audio Feed
That http;//www. should be blue and you should be able to left click on it and it should you you another page. On that page look for a speaker on the left side of the feed description and click on it. That should open up your media player and put you into the ballgame.
Your son is correct that SWR PD is going digital sometime soon. But when? I have been keeping tabs on Farrell within the FCC Database and as far as I can tell they have not even submitted and application for any type of license let alone any type of changes to their old ones.
Now Hermitage went digital and with total encryption. I can decode it with some software just as you can if you can pick up their signal. Living where you do you would be able to do it. If SWR PD goes in the same direction as Hermitage did I will decode it and it will be online for all to hear.
Ask you son for any and all info on the new radios they will be getting. Ask if he has seen them or knows anything about what they are going to be doing. Any and all info is good before they do anything. Try and stay on top of tgings if he will give up any info. If you want you can just send me a private message or and email if you have any info to throw my way. Let me know if you need any other help and I hope you can figure out how to listen to the feed. It is really easy to do. Good luck!
