Hytera DMR Tier I
Hytera presents: The world's first DMR handheld radios for digital PMR446 radio The new license-free digital handheld mobile radios from Hytera are among the first license-free DMR handheld radios in the world. They operate in the 446-MHz frequency range and were developed in accordance with the open Digital Mobile Radio standard. Their compact design and intuitive operation make these DMR radios the ideal companion for day-to-day business. www.dmrtier1.com Radios PMR446 Digital DMR handheld radio The open mobile radio standard DMR Digital Mobile Radio (DMR) is an open digital mobile radio standard for professional mobile radio (PMR) that was developed by the European Telecommunications Stan- dards Institute (ETSI). DMR mobile radio systems use a channel range of 12.5 kHz and, as such, are compatible with the frequency spectrum of analog mobile radio. As a result, mobile radio solutions based on the DMR standard enable a simple and cost-saving migration from analog to digital mobile radio. The DMR standard differentiates three different graduations in functionality and performance. The license-free DMR radios from Hytera correspond to the level DMR Tier I. Products in accordance with DMR Tier I are used for simple radio communica- tion in the license-free 446-MHz band and support a maximum transmitting power of 0.5 watt. For users who require a higher scope of functions, Hytera also offers conventional DMR mobile radio systems. Furthermore, DMR trunked radio systems are also part of the Hytera product portfolio. PMR446 – License-free radio for everyone PMR446 radios can be operated by any user without a special proof of need or a license. -
ECC Decision (15)05
ECC Decision (15)05 The harmonised frequency range 446.0-446.2 MHz, technical characteristics, exemption from individual licensing and free carriage and use of analogue and digital 1 PMR 446 applications Approved 3 July 2015 Amended 2 March 2018 1 Comparable technical specifications to those given in this ECC Decision are given in the amended EC Decision 2006/771/EC for SRD. EU Member States and, if so approved by the EEA Joint Committee, Iceland, Liechtenstein and Norway are obliged to implement the EC Decision. ECC/DEC/(15)05 Page 2 EXPLANATORY MEMORANDUM 1 INTRODUCTION The free circulation of radio communication products and the provision of equipment in Europe for radio communications are only achievable if there are common regulations throughout Europe regarding the availability of frequency bands, harmonised technical conditions and border crossing procedures. The main requirements for fulfilling these objectives for analogue and digital PMR 446 radio equipment are the Europe- wide availability of a suitable frequency band, harmonised technical conditions and the implementation of national regulations based on the Harmonised European Standard EN 303 405 [1]. PMR 446 is intended to operate on collective frequencies shared by many users on an uncoordinated basis. The equipment is hand portable (no base station or repeater use) and uses integral antennas only in order to maximise sharing and minimise interference. PMR 446 equipment operates in short range peer-to-peer mode and cannot be used neither as a part of infrastructure network nor as a repeater. The transition to digital technology in all sectors of radio communications is required in order to meet the user expectations whilst improving spectrum efficiency. -
Mhz As a Primary User
Response to Ofcom Consultation Q1. What future uses might this spectrum support? The availability of this spectrum is a rare opportunity. As such, the benefits should be made to the general public, as well the business stakeholders. 1. Amateur Radio:The UK Amateur Radio service is allocated the 2m band from 144.000 to 146.000 MHz as a Primary User. In comparison, the USA has an allocation from 144.000 through to 148.000 MHz. An expansion of this band by 0.5 – 1 MHz immediately above 146.000 MHz will be beneficial to the amateur radio community. 2. VHF Citizens' Band service: The UK only CB Service at 934 MHz was withdrawn in 1998, with the loss of 20 channels to GSM 900 Mobile operators. This is an opportunity to re-introduce a 20 channel CB service, at a frequency range which does not have the propagation characteristics of the 27 MHz band. An allocation at VHF will allow practical antenna lengths to be used in vehicles and buildings. In comparison, ACMA (Ofcom's counterpart in Australia) has sanctioned the use of a 77 Channel “UHF CB” service at around 476 – 477 MHz. 3. Simple UK (Business Radio): The business radio Simple UK licence permits 15 spot frequencies to be used at a 12.5 kHz bandwidth. The addition of more frequencies for this licence type will ease congestion. 4. A “personal use” radio service: There are a number of licensable and licence-free radio services available for individuals. This include PMR446 (licence-free) and the licensable Business Radio (Simple UK), as well as CB Radio on 27 MHz and a number of low-power allocations. -
PMR446 License-Free Radio Frequencies Following ECC Decision (15)05 and What It Means to You
White Paper August 2016 A guide to the new PMR446 license-free radio frequencies following ECC Decision (15)05 and what it means to you PMR446 (Personal Mobile Radio 446) was conceived as a European licence- free two-way radio system and was introduced in Ireland in 1998 and a year later in the UK; where it successively replaced the former licensed Short-Range Business Radio (SRBR) service. It was intended as a simple and cost-effective basis for instant voice communication between users with both transmission and reception taking place on the same channel (single frequency, simplex traffic). Unlike mobile phones, with PMR446, calls are unlimited and free and there are no subscription charges or licence applications to complete making them ideal in situations where instant voice communication is required over distances of up to 6km (actual PMR446 coverage depends on terrain and environment) and where GSM signals can be patchy. Another benefit of PMR446 is that compliant equipment may be used in the following CEPT (European Conference of Postal and Telecommunications Administrations) territories and their overseas or semi-autonomous territories without restriction: Austria Iceland Portugal Belgium Ireland Romania Bosnia and Herzegovina Italy Russian Federation Bulgaria Latvia Serbia Croatia Liechtenstein Slovak Republic Cyprus Lithuania Slovenia Czech Republic Luxembourg Spain Denmark FYRO Macedonia Sweden Estonia Moldova Switzerland Finland Monaco Turkey France Montenegro Ukraine Germany Netherlands United Kingdom Greece Norway Hungary Poland Includes the overseas or semi-autonomous territories of Denmark, France, Greece, Italy, Netherlands, Norway, Portugal, Russian Federation, Spain plus the constituent parts of the United Kingdom as well as the Channel Islands and the Isle of Man Please note: Assignments for use of licence free radios may change from time to time and the user is advised to check if PMR446 equipment can be used in the destination country. -

Catalog of Dynamic Electromagnetic Spectra Observed with Callisto, Phoenix-3 and ARGOS
Physics, Astronomy and Electronics Work Bench Catalog of dynamic electromagnetic spectra observed with Callisto, Phoenix-3 and ARGOS Christian Monstein1 1 Institute of Astronomy, ETH Zurich, Switzerland e-mail: [email protected] Draft 30.04.2011 / Updated 15.12.2013 Abstract. This catalog demonstrates dynamic electromagnetic spectra observed by Callisto radio spectrometers. In the first part natural spectra are presented while in the second part we concentrate on artificial (man-made) spectra. This catalog shall help the scientist to detect and identify weak flares in highly interfered spectra. In addition, Callisto spectrometers have proven to be a cheap and reliable instrument for radio frequency monitoring of terrestrial interference. Key words. Callisto, spectrum, cross modulation, inter- ference, solar flares. 1. Introduction A catalog of different electromagnetic spectra is presented for the convenient interpretation of dynamic radio obser- vations of solar flares in view of ISWI (International Space Weather Initiative). Spectra are observed at different loca- tions worldwide and with different antenna systems within the e-Callisto network (Benz , 2004). Observations took place since 2004. The catalog consists of spectrograms all produced in the same way: bad channels with high σ elim- inated, background subtracted, and zoomed to the inter- esting part. Fig. 1. Noise storm of solar radio emission observed at Bleien 2. Solar spectra observatory, Switzerland. Antenna = dish 7m, circularly po- larized. A chain of type I bursts is shown. In the collection below most of the typical solar radio bursts will be presented and shortly discussed. A detailed description of the physics behind the bursts can be found bandwidths of a few MHz and lifetimes extending from 0.1 in the publication by Kundu (Kundu , 1965). -
