hows that frank?
you call bs, well then, explain. enlighten me and others with some wisdom and not call wolf and close the door.
If my info is wrong then I want to hear the correct answer so that me and others won't trip over our shoelaces.
Or do you call wolf, shut the door and only worry about your own protection and not that of others.

Here you go. from the man himself:The signals are sent out scrambled, reach the intended radio that has the software installed to descramble and that's it. If it was something magical you wouldn't be able to buy USED municiple/police radios of the net. They have just been deprogrammed:
NLETA
Trunked radio in its simplist terms is this. Your agency has a group of frequencies. Lets say your trunked system has four frequencies. There are 12 people talking to each other, and all are on the radio talking at the same time, but they are sharing the four trunked frequencies.
The trunked system is taking the senders voice and breaking it up into a digital language string, of 1's and 0's. It now sends this digital string over one of these channels to the other radio which changes it back to a audible voice. When the reply is transmitted back the system may automatically choose different channel. The system is so sophisticated that it looks for a channel with no activity and routes the signals back and forth using any available channel. Because of the compression and being digital the 12 (OR FAR MORE)conversations can go alternately over the four channels so quickly that nothing is lost and people are unaware of the other conversations going on. I'm sure someone can explain it better than me,and I hope someone does.
800 Trunking is is actually a very elaborate way to utilize the available bandwidth. It is also being forced upon many agencies as they grow out of their current systems and need larger systems. I can't help but think that the big radio providers ( Motorola, Erricson/Comnet,Johnson) didn't have their fingers in the FCC /Government cookie jar because they will profit greatly from all the new systems being required.
The FCC has new frequency use plan that they refer to sometimes as refarming. The government is trying to pack more users into
the same space by using tight bandwidth restrictions etc. big trouble is that the systems don't play well with each other. Motorola has a system. ComNet has a system, etc etc.

You know, the man has websites/forums just like we do. And yes they can be viewed partially by the general public. Although the juicy information can't be seen unless your a member (verifiable LEO), know someones log in and password, or hacked into it.
Perhaps instead of sitting on weed sites 24/7. Folks should read/lurk around other sites and get the 411 on them. Like us, there's always a few that run their mouths to much and give away info.
Just use common sense and don't visit from your own computer/connection in case they store info.

I will tell you what if you can (or have access to) a way to beat 128bit encryption lets get together and get rich.

haha. I wish I did 'bro. I sure wouldn't have to worry about whether I'll get S.S. in a few years. I'd go BIG one time, get my share and the USA could kiss my a*% and that would be it.
And if it is not done the way wiseone posted...LEO's simply use their cell phone if they want to eliminate the chance of anyone listening in.

i know this much my step father use to be an undercover cop and was deputized alot in other cases he owned a police scanner after gettin out of that it was probably five to ten years old that still worked fine we used it for years and never had to have it reprogramed. just my two cents and sorry to add to all the paranoia but i'm no cop so chill lol.

wiseone
Many do.
It's harder to use a scanner to pick up the cells even though they broadcast in a range that can be scanned. Imagine being in NYC or LA trying and trying to figure out which conversation is a cop or not from all the cell phones you'd listen to. Most major cities would probaly overload the scanner with to much transmissions to make it worth it to use a scanner on a cell.
A good website to lurk on is OFFICER.com
here's a little more tidbit from their public viewing forums about the radios and how the transmission Can be decoded:
AGAIN....ALWAYS USE A DIFFERENT COMPUTER/CONNECTION IF YOU VISIT. I can't stress this enough
Originally posted by slolightbar:
<STRONG>I have used 800 mhz. products, and think their crap. There are ways of decoding the encryption, dont need calgroups as there are more and more radioes that have huge channel banks (256 channels and more), and Ive also found MANY dead spots where NO TRANSMISSION goes out. At least with analog, a scratchy signal will go out that might be understandable in a case of 11-99, etc.
VHF for example, stands for Very High Frequency. It is made for long range transmission - sort of line of sight. more for SO's, racetracks, things like that that are outside. UHF stands for Ultra High Frequency. You must understand that the higher the frequency, the better it penetrates objects. SOOOOOOOOO... thats why most PD's are on UHF, as they are in and out of buildings and in highly populated areas where there are buildings. Places like Costco, Walmart, etc. use UHF freq. radios, as they penetrate the building better. Repeaters also play a big part in transmission. BTW, next time you go into Wal-mart, look up in the center of the building, there is a white ball hanging, its a repeater!! I find that kind of pointless, because those little spirit radios they use dont need a repeater in a small building like that!!! ANYWAYS.... hope I cleared up some confusion. </STRONG>
I totally agree, our 800mhz are pretty crappy, but they are better than the UHF we had before. We also have better features for officer safety including a "Code 33" button and transmission prioritizing through the director. We still run seperate channels or talk groups for our PICs, but we also now have features such as unit identification as soon as the mic is keyed; barring the radio banks assigned to certain plain clothes units which can be randomly signed out to different units.

I was under the impression that the latest and greatest digital LEO radios used encryption and frequency hopping or spread spectrum. Neither the analog or digital scanners that Radio Shack, etcetera sell will do much good in those circumstances.
It may do more good to be situationally aware, observe appropriate security measures, and avoid any sort of visible profile. Instead of spending | wasting money on scanners, how about installing small solar-powered Wifi cameras and Wifi repeaters around your neighborhood?
You may not "hear them coming", but you could certainly see them.

That old would have made it analog. No problem there. He knew what the restricted frequencies were and probaly punched them in himself.
Now days a lot are digital which is the area this conversation is focusing on.

In the military we had iether single channel commo or we could program our radios to frequency hop for operational security. With frequency hop we would get a new program for the radios usually every 24 hour depending. We would give a device called a plugger to the commo section every morning and the would give it back with the codes loaded on. We would then plug the plugger into the radio and program our hop for the day. What is going on is the radio is bouncing back and forth through numerous channels very rapidly. Unless you knew the random code or had acess to the person who wrote the hop code listening in is impossible. I asume police have the same equipment on the swat and drug task force levels. Older scanners can however be used to listen in on cell phone conversations quite easily. New scanners have the cell freq. blocked out on them. Under the battery you will see the freq. your cell phone operates at. Punch that into a old scanner and you will hear some of the damdest conversations.

^^^^ That could be true...hmmmmmmmm........time to find a secure wifi, get the dirty computer out and investigate/research.
Nothing is impossible.......just need to keep hunkered down until you find a answer.
Remember if it was programmed it can be unprogrammed and the military has a lot more to lose than a cop in some city going after street corner dealers.
I will investigate and see what I can find.

Its not illegal to listen to or have a scanner at home, it is illegal to talk about or record the information heard in scanner transmissions. Police systems today are mostly trunked. You can pick up anything as long as you put your local city's trunk frequencies in order. You can pick up everything from narc/gang/vice to city water department or maintenance. You need to know what talkgroups are what because on most scanners they only show up as ID numbers... It doesnt help having one around when you get in trouble for a felony that might benefit from you having a scanner.

That's why one needs to get one of the used radios from the net. They are on Ebay left and right. Problem is making sure it's compatible with what LEO is using in your area and having someone program them. If they have Motorola's and you have Ericcson then that's like me having an orange and you an apple.
Radio Shack scanners are good if you just need to listen to whats happening around the area with uniformed officers and maybe the jump out boys, but for narc/vice then yea you need a regular radio that has been re-programmed.
I know a lot of this info might be a waste of time for some who are in a mmj state and only have to worry about the Feds kicking in the door ( and if the feds are coming for you a scanner sure as hell ain't going to save your ass), but for folks like me, here in NOVA who can get 35 years for one freaking plant, I want all the insurance I can get.

If one thinks a scanner is enhanced insurance then that person is just fooling himself.
Probably the only way to monitor a digitally encrypted radio system is to "social engineer" a working radio in other words a give away and even then with a modern trunking radio system if that radio is listed as missing or stolen the system administrator can brick it (make it not work) as each radio is individually addressable. a hardware hack while not impossible is difficult enough that if you could do it you would doing something much more lucrative I'm not trying to troll here just telling the truth

touche' strainhunter.
Its not the only method I use to protect myself, just one.
For myself I have rules that I live by that have kept me safe in the 27 years I've been growing (KNOCKS ON WOOD LOUDLY).
1. Never tell no one
2. Never show your grow in person or in pictures (past/present). In fact don't take pictures at all. That shit ALWAYS comes back to bite one in the ass when you least expect it.
3. Any electronics are ALWAYS bought under a false name in a different state. For me I can be in DC or Maryland in minutes.
4. Register them under the false name as well. And I NEVER keep that computer in my home or at my grow.
5. Always surf these sites/seed banks and other deeds I do from a connection that is not associated with me or anyone I know.
6. Maintain a normal lifestyle. You know the bit.....normal hours, clothes, 1 car. No excessive spending of $$$$$. ( This violation is usually what gets folks busted....they bring attention to themselves)
There is other rules but I'm sure everyone gets the idea.

True and really not worth the trouble unless someone was really growing some weight. And in that case if someone is growing/selling like that they esp. in a major city, I'm pretty sure they have the connections to give them the heads up to dismantle and chill for a while.
Just trying to show that things can be done.
It's been fun, but I need to get ready for work.

Most departments have made the "switch" to digital radios, rendering your old piece of shit scanner you bought at a garage sale "useless".
There are currently 2 models of radios that are capable of picking up the new action, both available in hand held and stationary at home units.
There may be more available now, but the best without a doubt would be the Uniden Bearcat BCD996XT . The new digital signal for scanners is called APCO 25.
So if shopping for a scanner, as long as it can pick up APCO 25 then your in business.
There is a company called scannermaster. They offer a service to pre program a scanner to your area(s), I would recommend this, You can pick up plenty of action depending what type of area your in.
I was on a trip in Chicago and brought my scanner with to the hotel and picked up great shit. Its entertaining to me. And I have heard plenty of Vice type stings,raids, car chases, and even a bank robbery.
In major cities with high crime, you'll get more of that. Don't expect to pick up raids if you live in the burbs.
It is nice to have at home though, and learn the codes, I like knowing whats going on around me.
Anyhow ...just a rant.

Ps. channels and systems like the most used APCO 25 "CAN" be picked up by modern scanners. And in the privacy of your own home are legal in many states.
