You mean the closed sky network that didn't work in the 70 % of the state for years.
Our PSP just started last year using the system in the car and as a working radio system. Bad design for PA just too much hilly terrain.

All it would take would be for someone to get access to the radio receiver portion of the system - such as surplus equipment that is sometimes sold at auction or on the internet, that could be hooked up to a computer and then rebroadcast over the internet.
It's all digital - one's and zero's - so there has been many people who have tried to decipher the binary codes necessary to make a radio capable of receiving those signals. The problem is - even if you did figure it all out - all they have to do is change one thing in the codes every day to make your system not work again. Similar to what the Dish Network had to do with it's smart card technology.
To go one step further, where I live, it is very mountainous and in order to get the system to work most of the times, they had to put up one antenna every 5 miles out in the woods. In all actuality - it would have been cheaper to just give them regular old cell phones and call them or keep using the radios they already had in the car and stay on the 150 mhz frequencies they already occupied.
My guess is that the digital doesn't like the low bands because there is too much interference and that the 800 mhz is a lot cleaner then the 150's and so it is pointless to keep two redundant systems around when it can all be done with one system.
At some point the energy consumption inside the car is going to get too great and they will have to find an alternative system that works. There is only so much that you can do with a 180 amp alternator. Especially when it takes 100 amps - just to run the car with all the on board computers that most new vehicles has in them these days.
Add their radio, their computer, their printer in the glove box, power supply to charge their cell phone and all the other junk in the car and pretty soon they are going to need a generator the size of 3 mile island to run it all.

We're working on it, trust me when I say that.
Just remember that OpenSky also is a radio based IP network, meaning the radio gear has it's own IP address and each user has their own login/password combo. Anyone on the system can use anyone else's radio, as long as they login as themselves, they will see their own radio profile, not anyone else's.
Also, remember, OpenSky has docs available to read. They can be found all over the Commonwealth's website.
Some counties also have patches from the OpenSky system into their system. None have the major action, mind you, but there are some things that are semi-monitorable via certain counties.
I'm not going to do all of the footwork for you and tell you everything, but needless to say, read those docs, and look at some Central PA counties talkgroup lists.
What I will leave you is this: Each county that has an OpenSky tower also has UHF interop frequencies. They are UTAC41: 458.4625, UTAC42: 458.7125 and UTAC43: 458.8625. They also have an 800MHz simplex that they can use as a unit-to-unit channel. That frequency is 851.4375.
Let me know if any of you find anything else. I will let you know if I do as well. Happy scanning!

Every day, I hear PSP do their radio check at shift change... Every day, their radio system that required small antennas be erected on poles all over the county, is "unreadable". So, they switch to VHF, and they're loud and clear. I think that PennDOT is the only one that actually uses it, here.
