simple way is to call a few signal hunting HAM guys and boom, this guy would have been caught and silenced quickly... but the police would be like, call WHO??? LOL

You are correct. The problem would be solved immediately. But the damage has been done. This is not the first time this has happened in the past on other systems. This crack head found a gap in the system and transmitted. This has happened on USCG Channel 16 before on coastal regions and The USCG has measures in place to pin point your immediately and they will murder you if you do this kind of BS.

Now the city or county has to re-evaluate their comm system. Maybe its just a blip on the radar and problem goes away. If not, and it continues then it will not be good news for the hobby down the road for people in your area. Keep in mind that systems in our area have been closed up and the gaps have been filled almost two decades ago.

Guessing you have not spent a lot of time in Chicago. And throwing crackhead out proves you are quite behind the times.

As far as the non-standard DPL not being a permanent fix goes, I have used this solution for many customers when I was in the business. One of which was a campus police department-that was in 1995 and they haven't had an issue with rogue operators since.

There are CCRs that can do any DPL, standard or not, like the Anytone 3318UV.

Perhaps quoting in context would be appropriate.

Yes, it's not completely undefeatable, but the effort involved goes beyond what most people are willing to expend for the cheap thrill.

I never said it was impossible, but you seem to want to make it look like I did.

I also don't consider a radio that costs more than my FT-60 to be a CCR....CR yes, but not cheap and most definitely not one that is being pushed hard in mainstream retail. Add to that the difficulty in determining the non-standard tone and it becomes not worth it for most that are currently causing the problems.

If a system is working, and a minor tweak keeps it working, there is no need for a radio shop to push a switch to a completely new digital system other than profit, which is my point. When you alienate customers, as seems to be the quoted case, as indicated by the statement:

Danny37 said:
My radio shop has been pushing DMR so hard and everytime I turn it down, nothing works as good as analog period.

all you do is push business to another shop.

Also, take a look at FEMA's Voice Radio Communications Guide for the Fire Service

https://www.usfa.fema.gov/downloads...communications_guide_for_the_fire_service.pdf

If analog is so decreased in performance compared to other modes, why does NFPA 1221 (as quoted on page 24) mandate analog fireground communications? EMS performs in many similar high noise environments.

After a similar type of incident on the old analog CFD channels, they switched to a "secure" digital system which many feared were going to be the big "E". Fortunately this ended being non-secured but their were channels made available that could be "secure". (I don't know if anyone really remembers on CFD how to get there).

I'm hoping once the dust settles and cooler heads prevail, the CPD will switch to the new Digital Trunking system sooner rather than later and have dispatch channels remain non-secured while tact and other sensitive communications are secured as many systems are, like DuCom.

But...only time will tell.

I was listening to this rogue radio and to be honest, it was terribly broken up and even when he spoke, it couldn't be heard. Many Zone dispatchers ignored him as he tried to make it sound like real CPD chatter.

No need for encryption Chicago...just join the rest of us in the 21st century and go P25, problem solved.

This analog radio system has been around since.......1970's and not much has changed. A few Zones added etc. But, they're getting there...slowly, but it's going to happen.

There's a slight chance this transmission was done by someone working for a major radio company, for the purpose of showing the department why they need to go to a trunking system at the very least. "See how easily people can interfere? Buy these 5000 dollar radios from us and there'll be no more of that!"

The city is already in the process of setting up a new digital system to move the CPD and all other city services to so if a salesman is doing that they're behind the times.

I don't trust Digital for urban environments like NYC and never will, we have a tough time as it is with analog.
P-25 has been proven sound in urban environments, like any system, depends on how it is engineered, implemented and maintained.



The system I was involved directly with implementing is a 15 site linear simulcast 12 channel 800MHz P25 phase 2 capable and blew the doors off the 30 year old Smartnet II it replaced. In building coverage is superb. Having encryption (and in the near future authentication) means you won't hear some turd calling fake "officer down" calls or playing recordings of anything, unless it's an actual subscriber, in which case, we'll go into RCM and kill it and deal with it internally.


We have over 6,000 subscribers and growing from countywide agencies to Federal law enforcement on our system. Not one has complaints that you describe.
Can't imagine what a mess it would be for digital.
It wouldn't happen to begin with, With authentication NO ONE can just clone an ID and access the system. Add AES-256 and you're as locked down as you can be from external sources of unauthorized access and system utilization. The ATIA captures everything a radio does when it hits the network, so if someone internal goes rogue, you've got forensic evidence to nail them to the cross.
Yes digital offers more features then analog but are they really used?
Let's see, we can dynamically regroup radios or groups of radios in an instant from a console in case of say, a major incident or terrorist attack (NYC would benefit from that I am sure). We can encrypt to AES-256 for COMSEC. We can ping a radio and verify it's on and what TG it's sitting on. (If we had location service enabled, we'd see where it is). We can private call between two radios (like iDEN) both in the clear and secure. We have emergency alert with revert and voice. We have wide area roaming with other metro area systems on talkgroups with a console presence that require ZERO operator intervention to use. We have the ability to produce DETAILED radio subscriber activity reports down to when a radio was turned on and off, what talk groups it was affiliated to, what sites/zones it registers with, detailed logs of each transmission made by that subscriber and who they interacted with talkgroup/private call wise, and match up with audio captured from our logging system from a single piece of software? Advanced noise reduction on fire radios makes them clear and crisp despite SCBA and engines blaring in the background. No static, clicks, pops, distortion, or listening to comparators working...shall I go on?

Analog has reached it's zenith years ago. Now with the proliferation of CCRs being mass marketed to consumers, you can rest assured what happened in Chicago will continue there and anywhere else uncontrolled wide open analog FM systems are used. Thanks FCC for allowing these road apple radios to flood the market. That should concern you more than "radio salesman" selling public safety products it wants: better, secure and reliable radios and systems to keep public safety employees safe on the job.

RDF is not impossible in the big cities, but in the urban canyons of Manhattan, or downtown Chicago, or anyplace similar? There's no much great multipath that you can easily get a stronger signal from a reflecting building BEHIND you, than you do from the real signal obstructed by a shorter building in front of you.

Calling some hams won't do it. The way to respond is by having a number of RDF units permanently installed on the roof tops of several command vehicles (i.e. one or two officers per precinct for a number of precincts) and then when there's a problem, you treat it the same way that LoJack responses are treated. You tell the lieutenant, whoever, use your RDF and give us some bearings. And you do this with multiple teams at once, so you can do it effectively.

Then you try to actually locate the party, and you bring charges for EACH transmission. Put one guy away for ten years. Put another guy away. Sooner or later, people start to realize there are other ways to get their kicks. And yes, that means selling the DA and the court on the concept of "public safety".

Anything less is just *icking around, and that's precisely why pretty much every ham radio club and the ARRL all say "just ignore the guy" rather than trying half-assed measures.

Or, of course, you could do it the military way. When they get an active jammer, they fire one anti-radiation missile. Which removes the jammer, the jammer's radio, and about a fifty meter circle of whatever was around it.

But in Chicago, that might tend to get the Mayor upset. And someone has to pay for that missile.

This thread is about the rogue radio incident and it's aftermath.

Please keep it on topic and civil.

There've been a few new incidents with racial epithets coming through the rogue radio - a few that really got the dispatcher riled up.

I always have wondered why CPD doesn't use a MDC Repeater tone/code to keep unwanted radios off of the UHF repeaters. It's very simple to implement and secures repeaters quite well. You would have to have the proper equipment plus be close enough to a transmitting radio to get the input audio and MDC signal. It's almost impossible. I mean there are ways to combat this on a analog system. I just wonder why more steps haven't been or weren't taken in the past to combat these attacks on the cities radio system. [emoji53]
