A subreddit for the low-cost, DIY software defined radio (SDR) community. While originally dedicated just to the project, relevant legal content related to general SDR, RF and similar projects is also welcomed.

Feel free to ask questions but please. Rtl-sdr 'rtl-sdr' is a generic term for cheap USB digital TV (DVB-T) receivers that use the Realtek RTL2832U chipset, which can function as general purpose software defined radios (receive only). All rtl-sdr compatible devices employ the RTL2832U as an ADC and USB controller, but different RF tuners may be used.

Note that rtl-sdrs do not transmit! Typical specs (some depend on specific tuner): • Cost: ~$5-45 USD • Frequency range: 24 - >1760 MHz (100 KHz - 24 MHz in direct sampling mode) • Max sample rate: 3.2 MS/s (2.6 MS/s in practice) • Resolution: 8 bits/sample • Noise figure.

Take a look here: What agency/system are you referring to? Forgive me, but I've run across many instances in the past where folks confuse digital voice with 'encryption' Best case scenario you need to look at using software like DSD+ with your RTl SDR dongle. If its truly encrypted voice your ability to crack the crypto is probably going to be quite an undertaking. There are some references to breaking encryption on a P25 system that I have come across. However if the agency in question changes the 'keys over the air' routinely its going to be a whole lot more trouble.

Sep 10, 2011. APCO P25 encryption is now (publicly) vulnerable to. View and Download E.F. Johnson Company 5300 SERIES operating manual online. DIGITAL/ANALOG MOBILE RADIO. 5300 SERIES Portable Radio pdf manual download.

As far as I know there are no 'stand alone' apps which can do the job for you. Most of the research I have seen regarding breaking voice crypto has been very technical and requires more than an above average understanding. (Proof of concept code is usually self censored by the researchers to protect from malicious abuse) I'm not saying 'give up, its not worth your time.' Although you might be unsuccessful in you endeavor to listen to 'encrypted' transmissions you might learn a few things along the way. One final note: In the US there may be legal ramifications to consider with breaking encrypted law enforcement traffic. But I'm no lawyer so Ill leave that aspect to someone else that thinks their google skills constitute a Bar Association certification.

It wont hurt to ask an officer about their radios, however don't be discouraged if they say 'our radios cant be monitored.' About 4 years ago I was talking to one of my classmates who happened to be local law enforcement. He was completely shocked when I told him that I had a scanner at home that could monitor their agency.

(a GRE PSR500 I got off of amazon.com) Apparently, either from a misunderstanding, or lack of training he was under the impression that the trunked Motorola system with P25 digital voice, was not able to be monitored by anyone. Although this may have been true when the system was first implemented many years ago, there have been many scanners on the market capable of monitoring such a system for quite some time.

As someone who has worked in public safety, I can tell you many of the people who I worked with considered their radios to be a 'magic brick' which allowed them to talk with their coworkers. In general most LEA training does not include the technical aspects of their radio system.

Instead training is focused on the basic operation and care of their radios. How to change the battery, select talk groups, and sites. Really basic stuff. Of course it never hurts to ask. Ive known a few folks in the public safety world that actually take interest in that sort of thing. I think, however, you will find the forums/database on radioreference.com to be more helpful. TETRA is more a European thing.

Filipino Movie Download Website more. More likely to be DMR or APCO P25 in the States. Give a try, it's entirely possible it's digital but unencrypted (unless you have reason to believe otherwise). I live in a town where no information is relayed to the local population even freedom of information acts seem to be bypassed. Spare a thought for us in the UK where it's countrywide and Airwave (our TETRA implementation) is about as locked down as a comms system is possible to get, 256-bit AES with TKIP (IIRC), monitored by the security services, and if you dare question why you're a terrorist.

The PSR800 is (was) GRE's introduction to the 'simple' digital scanner made for people with limited programming knowledge. The menus are fairly simple but not all self explanatory. We now have unlimited memory available on a microSD card along with the for the US and Canada.

Like the PSR500/310, the PSR800 uses for storing channels but now has 201 scan lists. The scanner also has 20 scan sets that allow you to group your scan lists into sets to make it easier to select them. More V-Scanner folders too, 200 vs. 20 in the older models.

It has a few new features including a recent firmware update that allows you to add channels to scan lists based on your zip code/city/county, the nicer 'Bold' font the 310/410 uses, programmable flash patterns for the alert LED and/or the backlight, and a real-time battery meter. There are options for dealing with encrypted talkgroups that include silence, an adjustable tone, or hearing the garbled transmission as is. You can also record specific channels then save and playback the audio later.

And, a power-on timer that can be set to turn on in scan, weather, or channel monitor mode. It comes with free software required for uploading/downloading and for updating the firmware or database. The advanced features (notably beta Motorola X2-TDMA and Phase II TDMA support, more memory, and the scan sets) make it prized by advanced users but the incomplete menus, lack of a full keypad, and the absence of many key features from the 500/310 models turn a lot of people away.

The scanner is really made for the 'set it and forget it' type of user. While you can edit objects and import from the library with just the scanner, there are some things you can't do with the scanner and have to do with the software including program/edit single frequencies, set receive mode, set/pre-store CTCSS/DCS/NAC tones/codes (you can store on the fly), set delay time, toggle audioBoost, channel digital mode, toggle LED latch, update the scanner firmware/DSP, and then programming and settings of all trunking systems and sites. And then oddly, all the searching/Spectrum Sweeper options can only be set in the scanner, there are no settings for those in the software. What happens when you plug the scanner into the computer has become quite strange if you are used to older scanners. Turn off the scanner and connect the USB cable to upload or download. Depending on what you are updating or transferring, it could take up to 10 minutes to complete.

Gone is the high-speed interface we had with the 106/197/310/410 models. An optional card reader may be faster if you are going to be transferring a lot of scan/play lists. Turn off the scanner to charge the batteries when plugged into the computer (only if you enable the charger on first) unless you're using the (optional) AC or DC USB adaptor. Pretty complicated. I think they went overboard on some of the features for an 'EZ' scanner like light colors and flash patterns and most people won't be programming their IDs in HEX format. There are quite a few settings that are dependent on other settings and make it confusing for even experienced users.

Example: one setting for alerts on, another for the alert volume, and then another for the object to use an alert, all in different places in the menus. Attenuation is another setting that is in multiple menus (global, system, site, object) that has to be carefully checked along with the AGC settings.

There are quite a few things that just don't make sense. Unless you are in a very bright room, the display is hard to see without the backlight on. Anytime you want to do a quick edit for a channel, i.e.

Attenuate, lockout, set priority, the scanner spends too much time re-writing to the SD card. The ATT key won't attenuate a channel; it just toggles global attenuation. While it boasts a clock, it only works when the scanner is off and plugged in and with no backlight (unless you press the power button). Another quirk is that the bandplan setting has to be set to 'USA' to for the 'Set Location' option to be visible in the main menu (no location database for Canada), but I still prefer to use the Canada bandplan for searching in the US. Then you have just the manual on CD, no printed manual.

Seems a bit ridiculous that you need to have a PC (and what about MAC users?) to fully program or edit a hand-held (i.e. Mobile) scanner.

Again, two steps forward, three steps back. The Pro-668 is basically the same radio as the PSR800 but the newest firmware will allow you to charge the scanner when connected to the USB cable (only when there is no audio-not receiving). Like the WS1080, the backlight is a bit more purplish. Because only a few settings/options are available in the scanner itself, this manual will also explain how to use the EZ-Scan/iScan software which is required for any custom programming.

Purple text will refer to the PSR800/Pro-668 instructions, and Green text will refer to Software instructions to make it easier to find steps with the scanner or software. In the table of Blue will pertain to both. Fgt Rumble 3 In 1 Driver Windows 8. The manuals that come with the scanners are still poorly organized IMHO and is only a pdf for the PSR800.

This manual should make it easier for most people to use the features of the radio as I will try to explain procedures a little more clearly and in a more logical order. And, thanks to the many people who have posted their valuable insight on the and. An overview of the features can also be viewed at my page.

There are better antennas out there to use than the one that comes with the scanner. RS has the for $15 - better for VHF/UHF. The for $25 - 100% better for 700+ MHz but keep your stock rubber duck handy for areas with a lot of 800MHz overload, especially with digital. You may be able to find others on the web but RS is convenient so you can buy it and take it back in the same day if you don't like it. Read the reviews for each at the site.

For those of you who are new to or haven't had a scanner in the last 10 years it is a good idea to read the respective sections on those topics. You really have to know how trunking works in order to program a trunking system. It won't do you any good to try to program a trunking system unless you know what the radio needs and is going to do with the data (control channel, IDs, LCN order, etc.). I will assume you know how to obtain the basic information from the original manual such as following safety procedures, putting the batteries in, connecting the antenna, etc.

As I will concentrate on the operation and main functions of the scanner. I hereby absolve myself from anything that happens to anyone or the scanner as a result of the information you will be reading. You are welcome to copy and/or print these pages and use them in the scanning hobby as long as you don't change, redistribute, or charge/accept money for them. I have tried the best I can to make sure everything is accurate here but if I missed a step, you see something that's obviously wrong, or have any other information you would like to contribute to make this manual better for everyone, please me. Check back often as this document will be updated and revised from time to time.

Searching- the process of searching for frequencies in pre-programmed service searches, Spectrum Sweeper bands, and the limit search. Pause Mode- used for monitor single objects or frequencies. Update Mode- used for updating firmware, the library (database), and uploading/downloading to/from scanner using a computer.

Playback Mode- used for playing recordings. Understanding Object Orientated Memory First we had 'Dynamic Memory' to get used to and now we have 'Object Oriented Memory' to figure out. Memory organization is nothing more than a large collection of scannable objects assigned to scan/play lists. A scannable 'object' is any frequency or ID. Trunking systems and sites are configuration objects that are used to scan ID objects.

Trunking systems/sites are not assigned to scan/play lists because you don't scan a trunking system/site; you monitor the IDs it generates. You only have to program any object once, then it can be scanned from any list(s) it is assigned to.

Like Dynamic Memory, you use only the amount of memory you need. Unlike Dynamic Memory, you don't have to 'build' systems or groups first to program them.

They are 'created as you go'. Also, there is no limit (except total memory) to the number of conventional systems, IDs, or conventional channels for each list. Each scannable object can be assigned to one or more of the main lists (1-200) or the ' ' (201). Each list is scanned like a traditional bank.

The main lists can be scanned with any other list but when the 'Skywarn' list is selected, only objects in that list will be scanned and no other lists. 20 Scan/Play Sets Scan/Play Sets you let you quickly select large groups of scan/play lists to enable or disable just by enabling or disabling the scan/play sets that contain the scan/play lists instead of individually selecting each group of scan/play lists. Firmware version 1.6 (PSR800) added a 'Scan/Play Sets Opt' setting. If enabled (checked), Scan/Play Sets alone govern whether a scan/play list is scanned and the master scan/play list enable array is ignored.

The allow you to save complete radio configurations. 200 V-Scanner folders are provided (plus the main memory in the scanner). Total memory capacity of main memory combined with V-Scanner folders is limited only by the amount of memory on the SD card. V-Scanner II folders are a new feature that update automatically in the scanner as you change/use them. Any changes that you make to the current V-Scanner folder in the scanner will be automatically saved to the microSD card.

Any changes that you make to the current V-Scanner folder in the software will be automatically saved to your computer. Unlike the V-Scanner folders in the Pro-106/197, it is not necessary to “save” and “load” them each time. Understanding Trunking. Trunking systems let a large group of 2-way radio users (or even different groups of 2-way radio users) efficiently use a set of frequencies.

Instead of selecting a specific frequency for a transmission, the user’s radio selects a programmed trunking bank in the system when that user presses their PTT (push to talk) button. The trunking system automatically transmits the call on the first available frequency, and also sends (on a different frequency called a Data or Control channel) a code that uniquely identifies that transmission as a talkgroup ID (or just ID). So when you are trunktracking a system, you are listening to active IDs transmitting in the system (each using the first available frequency in the system). Trunking systems in general allocate and use fewer frequencies among many different users.

Since the trunking system might send a call and its response on different frequencies, it is difficult to listen to trunked communications using a conventional scanner. These scanners let you monitor the control channel frequency so you can hear calls and responses for users and more easily 'follow' conversations than with a conventional scanner. These trunking scanners trunktrack the following types of systems: • Motorola Type I • Motorola Type II • Motorola Type IIi Hybrid • Motorola Type II Smartnet • Motorola Type II Smartzone • Motorola Type II Smartzone Omnilink • Motorola Project 25 Standard • Motorola Project 25 X2-TDMA • Motorola Project 25 Phase II TDMA (PSR800 with firmware >1.7) • EDACS Standard (Wide) • EDACS Narrowband (Narrow) • EDACS Networked (Wide/Narrow) • EDACS SCAT • EDACS ESK (not ProVoice) • LTR Standard. When you program Motorola frequencies into the scanner, one frequency is the control (or data) channel, and the rest are voice frequencies shared by all the users. There may be 3 or 4 frequencies assigned as (primary or alternate) control channels but only one control channel will be active at a time. These scanners will allow you to program just the Motorola control channels into the trunking system and the voice channels will automatically be found. EDACS systems need all the frequencies for the system programmed and in the correct LCN (Logical Channel Number) order.

The control channel is continually transmitted to the field units and has a sound similar to listening to a boat engine over the phone (in manual mode; you won't hear this when you are trunking the system). This control channel is also a good check to see if you can trunktrack the system. If you can't hear a control channel when you step through the trunking frequencies (in manual mode), you either don't have all the frequencies or are too far away to receive the control channel and the system. Motorola systems are limited to a maximum of 28 frequencies per system, Ericsson EDACS systems are limited to 25 frequencies per system. LTR systems work a little differently. This type of system encodes all trunking information as digital subaudible data that accompanies each transmission.

LTR systems typically do not have a dedicated control channel. The frequencies also have to be in LCN (Logical Channel Number) order or the correct 'slot' for the system to trunktrack properly. These radios have a ' ' feature that allows you to enter the frequencies in any order in the scanner will position the frequencies in the proper 'slot' base on the received subaudible data. Each repeater has its own controller, and all of these controllers are synchronized together. Even though each controller monitors its own channel, one of the channel controllers is assigned to be a master that all controllers report to. Each of these controllers sends out a data burst approximately every 10 seconds so that the subscriber units know that the system is there. This data burst is not sent at the same time by all the channels, but happens randomly throughout all the system channels.

If you listen to the frequencies of an LTR system in manual mode (not trunking), on every channel in the system you will hear this data burst that will sound like a short blip of static like someone keyed up and unkeyed a radio within about 500 ms. LTR systems are limited to 20 frequencies per system.

Trunkscanning is basically scanning IDs that are programmed into ID locations (same concept as frequencies into channels). You can then trunkscan just the programmed IDs.

Trunktracking is searching for all IDs in a system (same concept as searching for frequencies in a band). Understanding Multi-Site Trunking Some Motorola and EDACS systems covering a very large geographic area use multiple antenna sites that each operate on different frequencies and use the same talkgroup IDs for traffic. Each site will have its own set of trunking frequencies and is monitored like a single system. All talkgroups in the system are available to every site so they don't have to be reprogrammed for each site. Each talkgroup object can be assigned to one or more scan/play lists but only assigned to one trunking system. Radio Reference.com has an excellent page explaining the various types of trunking systems in more detail.

Understanding IDs ID Formats Motorola IDs come in two formats: Type I and Type II. Each format displays and uses Talk Group IDs in slightly different ways.

Type I/II hybrid systems use both Type I and Type II formats for Talk Group IDs. Type I IDs are in the format BFF-SS where B is the block, FF is the fleet, and SS is the sub-fleet. Type I systems are usually organized with different IDs assigned to different fleets.

For example, a valid fleet/subfleet ID identifying all detectives within a police department might be 000-12, where 000 identifies all police IDs and 12 identifies the Detective division. To properly trunk a Type I system, you have to program the fleet map for the system. Type II IDs are identified by a 5-digit number. EDACS IDs come in two formats: AFS (Agency-Fleet-Subfleet) and Decimal. AFS IDs are in the form AA-FFS where AA is the agency, FF is the fleet, and S is the sub-fleet.

EDACS systems are organized with different IDs assigned to different fleets and agencies. For example, a valid agency/fleet/subfleet ID identifying all detectives within a police department in an agency might be 06-101, where 06 identifies the agency (Police), 10 identifies the Police division (East side), and 1 identifies the Detective division. Decimal IDs are shown as a decimal number from 0 to 2047. You can find a chart showing Decimal and AFS equivalents here:.

LTR IDs are in the format A-HH-UUU where A is the area code (0 or 1), HH is the home repeater (01-20), and UUU is the user ID (000-254). ID Types Group Wildcard IDs will monitor all talkgroup IDs on the trunked radio system. A wildcard TGRP object allows you to receive IDs that are not already stored as objects in the radio's memory.

Group IDs will only monitor talkgroup radio traffic on that specified TGID. Private Wildcard IDs will monitor all private IDs on the trunked radio system. Private IDs will only monitor private radio traffic on that specified private TGID. Radio IDs are group or private IDs associated with individual radios. Understanding Receive Modes Each conventional channel can have its own receive mode: Auto, AM, FM, or NFM. Auto - Receives transmissions in the modulation sent.

AM - Receives transmissions in AM modulation. FM - Receives transmissions in FM modulation. NFM - Receives transmissions in NFM modulation.

Understanding CTCSS/DCS/NAC Each conventional channel can have its own squelch mode: None, CTCSS, DCS, P25, or Search. None no codes will be searched. CTCSS - PL codes appear (if received) in the format xxx.x, where xxx.x is a frequency in Hz. DCS - DPL codes appear (if received) in the format xxx, where xxx is an octal code. P25 - NAC codes appear (if received) as a 3-digit hexadecimal number.

Search - the scanner will search and display any codes (if received). Continuous Tone Coded Squelch System (CTCSS), Digital Coded Squelch (DCS), Network Access Code (NAC), are three methods used to prevent interference by other radio communications. Your scanner can receive transmissions that use these codes (or sometimes referred to as tones). Coded squelch techniques involve the transmission of a special 'code' signal along with the audio of a radio transmission. A receiver with coded squelch only activates when the received signal has the correct 'code'.

This lets many users share a single frequency, and decreases interference caused by distant transmitters on the same channel. In all major metropolitan areas of the United States, every available radio channel is assigned to more than one user. Public safety radio systems on the same frequency are usually set up at a distance of 40 miles apart, or more. This means that you may hear transmissions from a distant system when your local system is not transmitting. By programming the code (or tone) for a local channel the scanner will not stop on transmissions from the distant system.

With few exceptions, such as the VHF Aircraft and Marine bands, almost every other VHF or UHF radio system uses some form of coded squelch. By far, CTCSS is the most popular mode among non-trunked systems. Usually, but not always, VHF channels will use CTCSS and UHF channels will use DCS. P25 (digital) conventional channels will use only NAC.

NAC, similar to CTCSS/DCS, has a 3 digit hexadecimal code that can be broadcast along with the digital signal being transmitted.
