Fundamentally, P25 is not inherently interoperable because there are different frequency bands you can use it on. Some of the non-technical people in the government do not get this. Thanks for adding to my point. It does not matter what type or radio/system you have. There are ways to interconnect them that are very inexpensive. Not to mention that the Kentucky interop standard is analog!

Anderson Co. Board of Education is doing test today on 157.680, analog and NXDN. It sounds like they are impressed with the improvement in coverage.
Garrard County Law Enforcement
As of yesterday, Garrard County Sheriff and Lancaster PD are now Nexedge digital. 155.580
Alot of people in Garrard county going to be disapointed they cant listen anymore......Sorry.

A government I can't monitor is one I don't trust. A government hiding behind NXDN or encryption is one that needs to be questioned.

I was told Hopkins County will be switching over to NXDN the first week or 2 of Aug.. Where is the best place to buy a Kenwood NX-200 ?

I agree, if the government dose'nt want you to know THERE HIDEING SOMETHING!!!!!!!!
When "Unit A" goes on a mutual aid call into Applebee County, what channel should they use? They should probably use Applebee County Channel 1 because it probably has the best coverage. That might be Channel 127 in Unit A's radio. If "Unit A" goes on a mutual aid call into Bumbletweed County, they probably need to switch to Channel 203. If "Unit A" goes on a mutual aid call to Ohio, they probably want to use Summiter County Ohio Channel 1 which might be Channel 1011 in Unit A's radio.
Programming all of these various radio channels in hundreds of different public safety radios must take a very long time. Writing the operators guide for the radio must take a long time also.
If all of the public safety radios in the USA had the same 100 channels, then training would be simplified and programming would be tremendously simplified.
The USA can either have one unified nationwide radio system - or the USA can have 100,000 different public safety radio systems. Something tells me the one unified system would be much much much better than having 100,000 different radio systems.
Does anyone have direct experience dealing with large complex computer systems? How are technological advances incorporated into the existing systems? How is new gear engineered into a 20 year old system? If 1 out of every public safety agencies in the USA start using NEXEDGE, and 2 out of 100 use Mototbro, and 3 out of 100 use P25 Phase 2, and others use TETRA or Tetrapol or LTE or whatever - everyone on different bands - I dont think the outcome is going to be pretty.

Can you monitor all the other information and communication that your government is exchanging on a day to day basis by snail mail, faxes, email, telephone calls and whatever but which is not made public?
What do you mean you can't!? - Well, I guess then you don't trust your government already and there is need to worry about encrypted radio traffic.

The government only wants you to know as much as they tell you and beleive only what they tell you. Anything else is illegal for you to hear. I understand the need for encryption for sensetive material such as for peoples privacy and national security. The state and government keep tabs on you, changing address when you move registering a vehicle ect. WE HAVE THE RIGHT TO KNOW whats going on in our community!!!!

I am afraid unless these scanner companies can get an agreement with these commercial radio company's to make scanners that will decode nxdn and the many other formats being developed..As far as scanning we are at the beginning of the end with all this encryption and i am tired of buying these 500 dollar scanners and soon to be bricks for a lot of folks..I agree with unit charlie,Why must every agency be encrypted?or digital?It's our gvmt at it's best doing what it can to keep the american people in the dark.Socializem at it's best they want you under their control like never before and depend on them for every aspect of your life.Folks its all down hill from here..
Not sure how you are hearing NXDN on 800 MHz. Neither Kenwood or Icom make NXDN 800 MHz radios at this time.
Range
I will say one thing in defence of digital. It does have much further range. There is a mixed mode P25 ham repeater here in Detroit. Handhelds programmed both ways, and runnng the same power, are getting about triple the range into the machine in digital mode, than they are in analog mode.

Boyle County EMS is using new NX-200's, wonder when they are going to switch to NXDN?
It's not just public safety radio going encrypted, but EVERYONE. I work on computer networks and now even the data on wired cabling between computers and servers in our work environment is configured for encryption. Encryption is used by cell phones, satellite TV, cable TV, DVDs (although easily defeated), web browsing (SSL), and many other modern technologies. After 9/11 and the resulting increased paranoid attitudes as well as documented hacking and interception of data from counties like China, everyone wants to protect their data. Even just 10 years ago, implementing encryption was a major cost, but today encyrption is nothing more than just another IC chip and small circuit on a motherboard turned on by simply enabling an option on the configuration menu.
The radios today are specialized computers with D/A converters linked to transceivers. Since the voice is already digitized, it requires little effort to encrypt/decrypt the data stream in real-time, especially with the faster microprocessor in these radios. When public safety organizations spend millions of dollars for new radio systems, they would probably like to use every available feature, including encryption. Many police departments know very well that the criminals as well as honest citizens monitor their radio communications. Encryption probably makes them feel safer knowing unauthorized personnel can't track their activities and some of this is probably being pushed by Homeland Security. Just as you wouldn't want some unknown person monitoring your wireless telephone or Internet buying using your credit card, many radio users don't want others to monitor their communications either.
I've been listening to scanners for nearly 40 years, but I've just about given it up even though I have several digital scanners. With the majority of nearby agencies using a Simulcast system (which is so garbled on my scanner that I stopped listening to them) and the increased use of in-car computers and cell phones by the officers, my scanner has gone nearly silent - especially now that our police dispatch all calls via their in-car computers. I miss the days when everything was discussed over the air and it was easy to monitor, but those days started dying when cell phones became affordable to use in the late 90's. There will come a day within the next 10 - 15 years when all radio communications are encrypted - whether by choice or by law.
For those that believe that they have a right to monitor public safety radio traffic in the clear, do you also feel you should be able to monitor all phone calls (both wired and wireless) as well as their in-car computer communications? At some point the hand held radios used by the cops will be replaced with smartphones so they can work just as effectively out of their vehicles. Their radios will likely become integrated into the smartphone (push to talk) and used only as a last resort.

Dakota91 - Thanks for your perspective on encryption. But - private conversations by private citizens are much different than conversations between public agents who carry guns. Peter Sz
PS - not to be a total downer - but if you dont think that government agents with guns can be a major problem, please read these 2 paragraphs - http://www.newser.com/story/100776/mao-greatest-mass-murderer.html - Mao (45M), Hitler (?10M), Stalin (?200M)
