Eavesdropping on Police Channels, Guard Frequencies: Old Radio in Basement, Obstacles & Tips

Question

Hello.
I found an old radio in the basement with such frequencies that theoretically should give advice and overhearing police channels, etc. and I wonder if you could overheat the police channels or guard for it if it supports such frequencies or there are some obstacles I do not know, because in All in all I do not know electronics very much

Frequencies are not everything. The type of signal modulation (amplitude, frequency, phase) is also important.
You must also know that any use of information obtained through such a watch is punishable.
I must also worry you. These services are provided by mobile phones and provide important information in this way. :-)

The police use communication equipment that encrypts the calls you will not hear anything.

I recommend to buy a terrestrial digital TV receiver based on the RTL2832U scalpel allows you to listen to the frequency of 22MHz - 1.7GHz and ksoztuje about PLN 40 (generally, I am interested in the topic of rtl sdr). Are we talking about the Polish police? I think only in Warsaw there is a digital radio being used, and in most cities it is just an analogue analogue narrow band FM, unprotected (for example, in my area it is 173.115MHz and you can easily listen).

Interesting things, Waćpan, you write ... Except for the exceptions (Tetra, Ericcson, Hytera, etc.) in our country in the blue bands FM modulation reigns supreme. The same in Health Service, PSP, PKP. Apparently there are plans for switching to the Tetra system, but how many years have you heard about it ...

A few years ago, I heard such a conversation in a regular FM radio, of course, in the radio band they had to set something wrong because they were stifling the reception of the radio. As for legality, it is rather legal that it is not like the air band.

The listening is completely legal, you can not transmit in these frequencies.

penpen · Answer

That's right, the listening is legal. In addition to the fact that you can not transmit it, you can not share the information heard on this band.

You will not hear anything interesting, as you mentioned from the Police, you will only hear messages of the type that the patrol will go to an address without details, the investigators use their cells. You will not hear much from the Fire Brigade, I only heard messages that the unit, eg number 1, goes to the action and how many people in the car and that they arrived at the action, maybe because I had a weak antenna and I did not hear the messages from the base. You can listen but you can not share the information you have gained from listening, so you can not use the radio in public so that the outsider can not hear it because the relevant services can include confidential information .

In Warsaw, just a few years ago, nothing could be heard, perhaps even in any province, you can read all the texts openly. The ambulance sends data to the ambulance through the terminal after GPRS including the street and the description of the patient.

The topic seems to have been exhausted and all important information has already been heard. @ death15331 If you want to play, buy a frequency scanner.

^ToM^ · Answer

You can listen without interruption, but you can not pass on the information you hear. You have to remember about it. Whereas now the services have gone digital, so you will not hear too much. You can play because you can learn something about how the radio works.

Ambulance Service or Border Guard will you listen? All of Kujawsko-Pomorskie, most of Podkarpackie, Podlasie, Warmian-Masurian and many other regions have long been in DMR. In Fire Brigade and on the railways yes. He would play if he led the discriminator and the receiver connected to a computer with a special softphone, eg DSD. What kind of equipment and what frequencies does it cover?

_siekier · Answer

In Dolnośląskie, still a lot of human harm flies in analog, but for someone to listen to passionately for hours, because sensitive data does not fly in the open ether, only digital communication or cellular networks. * Human harm - blue, PSP, health service. One could listen to analogue telephone radiolinks in villages - heh, life itself, good hstorie, and even wishes for various occasions could be learned quite well.

And to think that the NMT450 has long since shut down, and the bandwidth to this day is unused. They have been poisoning about LTE450 for several years, but nothing comes of it.

ptero · Answer

I once listened to several nearby hams, a few VHF repeaters, the Straż, Police, PKP, PMR, Radio Taxi, sentries at a nearby polygon, a military airport tower with nearby airplanes (in AM), ISS station, motor hangers, ships on the Oder river, several captains and ports.
And a passing balloon.
