I feel the same had many good years of listening.
You know, I could listen to anything in those days, and I just listened for enjoyment and my interest in communications. Didn't divulge anything, did not cause anyone any trouble. Kept it to myself.
Would never in a million years stream it to the public. That is just shooting oneself in the foot.
Most of what I heard was in the public domain anyway, (court records etc)
If I was listening in public I used headphones and it looked like I was listening to music. Would try to keep the scanner out of site.
Then when MDT's came into use there was much less private information given out. Next, in car computers, cellphones, so even less on the radio.
Anyway, I am grateful for those years, not complaining.

Re: crypto comm

I have been a radio hobbyist since the 1970’s. Started listening to scanners back in the old crystal days. I have seen the introduction of voice inversion systems followed by the Motorola DVP systems on the local police systems. Our local police service went full time encryption (DES-OFB and AES256) back in 2012. When that happened, the media (and scanner hobbyists) switched to monitoring the EMS and Fire comms and learned of all the major police events that way.
In 2017, Police and Fire went full time encrypted. As the comms system admin for all three services, we noticed a few very important benefits.
No one has “the right” to eavesdrop on another person’s or parties communications. For those that feel somehow that it is their duty to monitor the local law enforcement comms because they feel that will prevent some form of police corruption, Grab a brain. Have you ever heard anything on your local comms that could even suggest this was going to happen? If some officer was going to do something they shouldn’t, they are not going to disclose or discuss this on a radio channel that is most likely recorded.
If you were that paranoid, I would also think you would be in favor of secure comms. Do you want all your neighbors hearing that the local police, fire or ems were dispatched to your home. Oh what would the neighbors think? The gossip that could be started!
Secure comms protect everyone’s rights to privacy. The first responders and the general public whom they are serving. Does the scanning public need to know that you had a grease fire on your stove? Do they need to know that you fell off a ladder and broke your leg? Do they need to know that a relative in your home is stressed out, and having anxiety issues? Of course the scanning public doesn’t have a right to know these things.
As much as I have enjoyed monitoring, it is not my right to hear anything. I miss the comms and knowing what is going on around town. However I also realize that my fellow citizens have a right to their privacy as well.
Secure comms are here, face it, accept it and move on.

I think some just don’t understand the whole encryption process
toggle quoted messageShow quoted text
Most newer systems rekey over the air. Which means a radio has to authenticate with the system , be part of a crypto net to get the correct key. Then be available to get the new key , which can be sent at Will. A scanner will never be able to do this Introduction to P25Call Types and FeaturesINTRODUCTION TO P25 ENCRYPTIONEncryption in radio communications enables secure communication between parties and is achieved by loading the same key into all radios in a group. The key is like a secret number or password that must be known in order to decrypt the call. Radios in their group can then talk amongst each other privately, and no outsiders can intercept the communications. Although analog encryption is possible, this typically degrades the audio quality and also results in a reduced coverage area, as stronger RF signals are needed to clearly receive the encrypted calls. One of the key benefits of P25 Digital Radio over analog radio is the ability to securely encrypt calls without impacting the coverage area. Enabling P25 encryption is easy. A channel or group is programmed to use encryption and a key is loaded into each radio that uses that group. DES uses a 56-bit encryption key and AES uses a 256-bit encryption key. The type of encryption to use depends on the type of information you’re protecting. AES is a more secure form of encryption, however maintaining the security of that channel is more complicated. Policies and procedures will need to be put into place to determine who is allowed to access the secure channel. In addition, plans will need to be in place to determine what to do if a radio with the key is lost or stolen. Often this is easily managed by having more than one encryption key. Tactical teams that require a higher level of security may generate their own encryption keys for specific operations. They can tightly control or manage those radios, and have an up to date knowledge of their current status. A different key is used to encrypt general day-to-day communications and is available to a wide group of people. Because a large group of people have access to this channel and the key, it is considered to have a low-level security. If the radio is lost, it could take some time for this to be reported and disabled. And replacing the key and all of the radios will be a time consuming, costly exercise and may only happen on rare occasions. Larger systems may use a feature called over the air rekeying, or OTAR. This allows the updating of the key over the air and dramatically simplifies the process of rekeying the radios in the field. You do not need to physically touch each radio to load the key with a key-loader. However, OTAR still has an administration overhead to track down and follow-up on any problem radios that could not be rekeyed. This is common where multiple shifts, spare radios, and specialist vehicles mean radios are not powered on and active on the radio system all of the time. In summary, P25 makes it very easy to add encryption to a radio system. However, it is important to have a good plan in place to ensure communication stays secure and the administrative overhead of managing the radios is in line with the level of security required. This concludes our introduction to P25. We hope it was helpful for you. If you’d like to contact us please follow the link below or post in the P25 forums.

Agreed, some places like in North Dakota, and some places down south go as far as encrypting public works and parks and rec. I noticed that in a lot of areas around Chicago they’ve encrypted, but not in Chicago itself. I’ve noticed that a lot of places down south more then anywhere else they do a lot of encryption. In a couple of weeks I’ll be going to see my mom and she lives in Louden County Tennessee. The last few years I’ve been down there they have had some encryption, bbut upon checking rr it looks like both police and fire are encrypted now full time? On the county law talkgroups encryption would come and go but not on fire/EMS. I’ll let everyone know, but I don’t know what to expect there. I know that all law enforcement in Knox County is encrypted, and that is the nearest major city she is near. What are people doing in places that have a lot of encryption who want most of the coms to be in the clear? There never has been any posts anywhere to indicate any activity that has taken place as far as protesting the encryption.

The officers need encryption for secure communications. There are all sorts
of reasons why for example the following things are common over the air:
-victim info (sexual/Juvenile/domestic violence)
-NCIC (CJIS protected)
-Key holder info
-Suspect names (NOT proven convicted people)
-Officer locations/calls
-Officer to officer discussions (trying to figure out
options/enforcement)
-Medical info/conditions
This goes on. These guys are being attacked on a regular basis. The least
we can do is give them secure comms which is dirt cheap and included in just
about every radio off the shelf nowadays.
Also, question why you hold grudges with your local police and think they
