One of the original goals of P25 was spectrum efficiency. The radio spectrum is a limited resource. There are only so many radio channels that can be licensed in a given area. Analog FM channels used to be 25 kilohertz wide. As the spectrum became more congested, narrowband channels were introduced.

With the old 25kHz channels halved to P25 Phase 1 was designed to use the same bandwidth as a narrow band FM channel, meaning they could be used side by side, and narrow band FM channels could gradually be replaced by P25 digital channels. Phase 2 is more spectrally efficient than Phase 1, providing two effective channels per In P25 Phase 2, each physical base station provides two effective voice channels.

Another benefit of P25 Phase 2 is longer battery life. For radio to radio and conventional P25 operation, Phase 1 is still used.

This is a really good product i'm able to pick up all my local public safety frequencies and then some. This one needs programming before you scan so make sure you have someone program it if your a novice.Introduced in the spring of and finally available in June, we sold every one we had and were promised and just now are able to keep them in stock for regular purchases.

What makes the SDS so special? Why does it work so well? Why is it worth all the extra money it costs? Glad you asked! Traditional scanners do not work very well often with LSM systems but the SDS handles them much better, almost as well as a regular system radio like the police use. Other scanners tend to break up, miss words or phrases or just not hear it al all. Why, you might ask, does this happen? Simply put, a simulcast system transmits the same traffic on the same frequencies at the same time from 2 or more locations.

A simulcast system would transmit from multiple sites to provide better coverage within its intended operational area.

These signals then tend to arrive at your scanner with slightly different time delays. This causes interference and sometimes the interference is so bad as to block the entire conversation. This means that the SDS will receive these simulcast systems with little to no distortion or interference.

It allows other features and capabilities to be added down the road. While Uniden has not announced any of these features yet the possibilities are endless. The other big feature with the SDS is the color display.

The Detail mode is entirely customizable. You can place any of dozens of different fields almost anywhere on the screen and assign any color to just about any item. You can switch back to Simple mode and just have the basics, still in color or even switch to a simpler black and white scheme that works better in bright sunlight. The SDS is an amazing radio. If you have simulcast systems in your area then it works much better than other scanners.

While it is more expensive than other scanners it is well worth it! You hear that your system has upgraded to a Phase 2 system but your old Phase 1 scanner still works?

What gives? When a system upgrades to Phase 2 not only does the infrastructure have to be upgraded base station repeaters, controllers etc.Project 25 P25 or APCO is a suite of standards for digital mobile radio communications designed for use by public safety organizations in North America. P25 radios are a direct replacement for analog UHF typically FM radios, but add the ability to transfer data as well as voice, allowing for more natural implementations of encryption and text messaging.

P25 radios are commonly implemented by dispatch organizations, such as policefireambulance and emergency rescue service, using vehicle-mounted radios combined with handheld walkie-talkie use. Starting aroundproducts became available with the newer phase 2 modulation protocol, the older protocol known as P25 became P25 phase 1. The two protocols are not compatible.

However, P25 Phase 2 infrastructure can provide a "dynamic transcoder" feature that translates between Phase 1 and Phase 2 as needed. In addition to this, phase 2 radios are backwards compatible with phase 1 modulation and analog FM modulation, per the standard.

Public safety radios have been upgraded from analog FM to digital since the s because of an increased use of data on radio systems for such features as GPS location, trunkingtext messaging, metering, and encryption. Various user protocols and different public safety radio spectrum made it difficult for Public Safety agencies to achieve interoperability and widespread acceptance.

However, lessons learned during disasters the United States faced in the past decades have forced agencies to assess their requirements during a disaster when basic infrastructure has failed. To meet the growing demands of public safety digital radio communication, the United States Federal Communications Commission FCC at the direction of the United States Congress initiated a inquiry for recommendations from users and manufacturers to improve existing communication systems.

Interoperable emergency communication is integral to initial response, public health, community safety, national security and economic stability. Of all the problems experienced during disaster events, one of the most serious is poor communication due to lack of appropriate and efficient means to collect, process, and transmit important information in a timely fashion. In some cases, radio communication systems are incompatible and inoperable not just within a jurisdiction but within departments or agencies in the same community.

P25 is a collaborative project to ensure that two-way radios are interoperable. The goal of P25 is to enable public safety responders to communicate with each other and, thus, achieve enhanced coordination, timely response, and efficient and effective use of communications equipment. P25 is applicable to LMR equipment authorized or licensed, in the U. Although developed primarily for North American public safety services, P25 technology and products are not limited to public safety alone and have also been selected and deployed in other private system application, worldwide.

Pcompliant systems are being increasingly adopted and deployed. Additionally, the deployment of Pcompliant systems will allow for a high degree of equipment interoperability and compatibility. It is rumored that the licensing cost for the voice-codecs that are used in P25 standard devices is the main reason that the cost of P25 compatible devices is so high.

P25 may be used in "talk around" mode without any intervening equipment between two radios, in conventional mode where two radios communicate through a repeater or base station without trunking or in a trunked mode where traffic is automatically assigned to one or more voice channels by a Repeater or Base Station.

P25's Suite of Standards specify eight open interfaces between the various components of a land mobile radio system. These interfaces are:.

I read that this model has been discontinued and another article about upgrading the firmware. Thank you in advance. Last edited: Apr 29, RoninJoliet Member.

I have the xt and a GRE psr These are my phase 1 workhorses and handle starcom monitoring quite well where I'm at. Depending on where you monitor and if your system is simulcast, the XT may work for you. Even in a simulcast system, the "may" work for you if you are closer to one of the towers than the other ones in the system. If you take it in the car though, that may go out the window and your reception may vary.

I have used my XT on Starcom 21 and it has been fine. SMF said:. It sounds like I'll have difficulties monitoring any non-encrypted phase I Police and Fire because of my location. Would you agree? Thanks for all the input.P25 digital decode threshold adjustments allow user to control of how digital system are decoded inside the scanner. The P25 Threshold is a kind of "digital squelch setting". There's three variants in the Menu to help for the "novice", the "intermediate," "advanced' users, at least try to enable a 'bit' better decoding than standard Auto settings.

It is likely "the most important thing," besides good reception, of how well, the digital system, will be decoded. There are the additional caveats explained further in this article.

The adjustment s mentioned below must be done while you have good reception. The other side of that coin is, that the maunal adjustment s do absolutely nothing to fix reception issues. If you have bad receive, you'll have bad decode, regardless. Once optimized for a System, the threshold settings shouldn't be changed in the x96T or x36HP series, regardless of future interference or signal conditions, unless you have confirmation that the system engineers have actually made changes to the system itself which is highly unlikely.

Lets start at just viewing the screen, then onto defining and adjusting, and lastly additional digital decode refinements. Let's first make sure we have the P25 Level set option is set to Auto. While you viewing the typical scanner system talkgroup on an active digital channel on a receivable System display:. The next to last line on the display, should now show the "current threshold level" model dependentwith "AUTO" on the right, and in between with an active voice transmission, the digital bit error rate.

The last line on the display shows the 3 millivolt values in a 3-digit representation 1. The error rate should begin drop for each transmission and the threshold levels should have adjusted to its best setting. Then, once it's seem to have stabilize or with LSM P25 Phase I and II at least, where you can see and hear the best decode values, write down the values from the screen.

This is that System's "optimum decode threshold". You can generally see it doing this. Thresholds don't change. Most likely you can do better!!! The radio will remember this setting for that System and use it every time it has to decode digital audio.

Higher numbers are more permissive the thresholds for decoding are wider while smaller numbers tighten the threshold ranges. Go into the Menu and set the P25 Threshold to Manual, then change the number that most closely matches the System's "optimum decode threshold" that you wrote down, moments ago. Now I can offer a slight refinement: If you're having trouble with a P16 Moto type 2 system decoding digital P25 audio, slightly offtune the automatic setting.

Frequently the radio will auto tune to a setting that is halfway between the values that you can set manually. For example, it might finally settle to a low threshold of 1. Well, the trick that helps stop the motorboating is to pick the looser threshold side. In the example, instead of picking 1. Think of it as similar to setting the squelch looser for a conventional channel.

Even if it typically tunes to an even value, like 1. Works for a lot of people. During the beta test, we convinced Uniden to implement a slight change to the "Auto" functionality.The type of scanner you will need will depend on the type of radio technology being used in your area.
