DMR and Digital Voice Modes
DMR and Digital Voice Modes Presented by N7MOT – Lenny Gemar Amateur radio began with spark gap transmitters, evolving to Morse code and analog voice communications, all originally in the Low Frequency (LF) and High Frequency (HF) bands. Since those early days, many new modes, both analog and digital have been developed. These modes now span from the Very Low Frequencies (VLF) to the Extra High Frequencies (EHF). This presentation is designed to acquaint amateur radio operators with the Digital Mobile Radio or DMR format of digital audio communications, used primarily in the VHF and UHF bands. We’ll briefly discuss the other four Common Air Interface formats (CAI) before diving into the specifics of DMR.

Project 25 and Interoperability in Land Mobile Radio
WHITE PAPER 2014 PROJECT 25 AND INTEROPERABILITY IN LAND MOBILE RADIO • The Project 25 standard is unique in that it is a USER driven standard. • Multiple vendors support the P25 standard. • Motorola Solutions equipment interoperates with other vendors equipment. • Customers can and do have a mix of vendor’s equipment. • As technology and customer needs move forward, so too, does P25, which is an open and continually evolving standard. WHITE PAPER PROJECT 25 AND INTEROPERABILITY IN LAND MOBILE RADIO P25: A UNIQUE USER DRIVEN STANDARD Public safety agencies are challenged with keeping communities safe and protecting the lives of their officers, both in normal day-to-day operations as well as when a disaster strikes. Often, it requires agencies to work not only within their jurisdictions or agencies but also across multiple jurisdictions and agencies. Interoperable wireless communications is critical to coordinating joint and immediate response. The public safety community and mission critical land mobile communication providers have been working hand-in-hand for many years and have developed the Project 25 (P25) standards for interoperable mission critical communications. WHAT IS THE PROJECT 25 STANDARD AND WHO MANAGES IT? According to the Project 25 Interest Group (PTIG), “Project 25 is the standard for the design and manufacture of interoperable digital two-way wireless communications products. Developed in North America with state, local and federal representatives and Telecommunications Industry Association (TIA) governance, P25 has gained worldwide acceptance for public safety, security, public service, and commercial applications.” PTIG continues, “The published P25 standards suite is administered by the Telecommunications Industry Association (TIA Mobile and Personal Private Radio Standards Committee TR-8). -

Using the BCD996T with a GPS
Precautions Before you use this scanner, please read and observe the following. IMPORTANT! This scanning radio has been manufactured so that it will not tune to the radio frequencies assigned by the FCC for cellular telephone usage. The Electronic Communications Privacy Act of 1986, as amended, makes it a federal crime to intentionally intercept cellular or cordless telephone transmissions or to market this radio when altered to receive them. The installation, possession, or use of this scanning radio in a motor vehicle may be prohibited, regulated, or require a permit in certain states, cities, and/or local jurisdictions. Your local law enforcement officials should be able to provide you with information regarding the laws in your community. Changes or modifications to this product not expressly approved by Uniden, or operation of this product in any way other than as detailed by this Operating Guide, could void your authority to operate this product. EARPHONE WARNING! Be sure to use only a monaural earphone or 32 Ω stereo headset. Use of an incorrect earphone or stereo headset might be potentially hazardous to your hearing. The output of the phone jack is monaural, but you will hear it in both headphones of a stereo headset. Set the volume to a comfortable audio level coming from the speaker before plugging in the monaural earphone or a stereo headset of the proper impedance (32 Ω). Otherwise, you might experience some discomfort or possible hearing damage if the volume suddenly becomes too loud because of the volume control or squelch control setting. This might be particularly true of the type of earphone that is placed in the ear canal. -

Special Report 396XT
Special Report The Uniden-Bearcat BC396XT Digital Scanner Features, Operation and Competition A Scanner Master Ultimate Review Copyright 2009, Richard Carlson/Scanner Master Corporation Introduction The Uniden Bearcat BCD396XT is the follow-up to Uniden’s premier handheld scanner, the BCD396T, which has been discontinued. The ‘XT has more memories (up to 25,000 channels!) and many new features while retaining the 396D’s small form factor and price. The BCD396XT directly competes with the GRE PSR500 and Radio Shack Pro106 The BCD396XT adds such new features as allowing up to 500 talkgroups per trunked system (compared to 200 for the 396D), NAC decoding, Fire Toneout Search and GPS Support. Some of these features have never been available on any scanner before. The BCD396XT uses Uniden’s Dynamic Memory Architecture (DMA) instead of fixed Banks and Channels. This method of programming was introduced a few years back with the BC246T and is also used on such scanners as the BCD396T and BCD996T. While it has a similar effect as the GRE “Memory Object” system, the Uniden method is somewhat easier to fathom and program for many people. DMA allows you to program as many Channels, Systems and Groups as you can until the memory runs out instead of locking you into a fixed amount of banks and channels. The radio resembles the BCD396T but has a silver faceplate. Otherwise the general layout is identical, with a single multi-function control knob on the top, 16 button keypad on the front and 2 side buttons on the left side. The right side has the same computer interface jack and power jack, the earphone jack is on the top between the multi-function knob and the antenna.
