Citizens' Band (CB) Radio
Citizens’ Band (CB) radio – Authorising Amplitude Modulation (AM) modes of operation Permitting AM double and single side band CB radio in the UK Statement Publication date: 10 December 2013 Contents Section Page 1 Executive Summary 1 2 Introduction and background 2 3 Consultation Responses 5 4 Conclusions and next steps 10 Annex Page 1 List of non-confidential respondents 11 Citizens’ Band (CB) radio – Authorising Amplitude Modulation (AM) modes of operation Section 1 1 Executive Summary 1.1 This Statement sets out Ofcom’s decision to proceed with proposals made in our Consultation “Citizens’ Band (CB) radio – Authorising Amplitude Modulation (AM) modes of operation”1 (the ‘Consultation') which was published on 7 October 2013 and closed on 8 November 2013. 1.2 The Consultation proposed to amend current arrangements for Citizens’ Band (CB) Radio in the UK to allow the use of Amplitude Modulation (AM) Double-sideband (DSB) and Single-sideband (SSB) transmission on CB radio. 1.3 Ofcom specifically proposed to: • Authorise the use of AM emissions on European Conference of Postal and Telecommunications Administrations (CEPT) harmonised channels in line with European Communication Committee (ECC) Decision (11)032; and • Authorise such use on a licence exempt basis (in line with our authorisation approach for other modes of operation for CB). 1.4 These proposals followed on from work carried out in Europe. In June 2011 the ECC, part of CEPT, published a Decision, ECC/DEC/ (11)03 (the ‘Decision’) on the harmonised use of frequencies for CB radio equipment. The Decision sought to harmonise the technical standards and usage conditions relating to the use of frequencies for CB radio equipment in CEPT administrations. -

Citizens' Band (CB) Radio Spectrum Use – Information and Operation
Citizens’ Band Radio equipment– information and operation Citizens’ Band (CB) radio spectrum use – information and operation Of 364 Guidance Publication date: March 2018 Citizens’ Band Radio equipment– information and operation Contents Section Page 1 Regulatory and equipment information 1 2 Frequently asked questions 5 3 CB operating practice 8 Citizens’ Band Radio equipment– information and operation Section 1 Regulatory and equipment information Citizens’ Band (‘CB’) radio 1.1 Citizens’ Band (‘CB’) radio operates in the 27 MHz band. It is a short-range radio service for both hobby and business use. It is designed to be used without the need for technical qualifications. However, its use must not cause interference to other radio users. Consequently, only radios meeting certain specific requirements may be used. These are described below. How Ofcom authorises the use of CB radio 1.2 Ofcom seeks to reduce regulation, where possible. In 2006, we therefore made exemption regulations1, removing the need for a person to hold a licence to operate CB radio equipment using Angle Modulation (FM/PM). 1.3 In 2014, Ofcom made further exemption regulations2, which permitted the operation of CB radio equipment using two additional modes of Amplitude Modulation (AM) - Double Side Band (DSB) and Single Side Band (SSB). This followed an international agreement3 made in 2011.”. 1.4 CB users share spectrum in a frequency band used by the Ministry of Defence (MOD). CB users must therefore accept incoming interference caused by use of this spectrum by the MOD. 1.5 CB radio equipment must be operated on a 'non-interference’ basis. -

Part 95 is unique in that some of it’s Subparts don’t require an station license. These Subparts which require equipment approval but not operator license are the family radio service, radio control service, citizens band service and multi- use radio service. Background of Part 95 is that originally included devices which all required licenses. Over time some of the license requirements were dropped as the technology became more stable. Then some additional subparts were added which required equipment authorization but no licenses. 2 Part 95A- General Mobile (GMRS) Frequency Bands: – 462.55-462.725 MHz & 467.55-467.725 MHz General Technical Requirements – 95.621 - Frequency Tolerance – 95.631(a), (e), & (f) - Emission Types – 95.633 - Emission Bandwidth(s) – 95.635 - Unwanted radiation – 95.637 - Modulation Standards – 95.639 - Maximum Transmitter Power – 95.655 - Frequency Capability October 2005 TCB Workshop 3 This slide shows an overview of 47 CFR part 95 Subpart A General mobile radio service. -

VIRGINIA SECTION HAM RADIO NEWS QSL! #17 September 2020
VIRGINIA SECTION HAM RADIO NEWS QSL! #17 September 2020 Dave Minyard KM4FOX, Newly- Minted VA ARES PIO ,Gets the Word Out! Dave Minyard KM4FOX has hit the ground running in his new position. VA ARES PIO. Over the past few months, Dave has worked hard on getting the word out. When the new VA Section ARES-VOAD relationship developed, Dave sent out Press Releases and Letter to the Editors to a plethora of news outlets in the Commonwealth. During the first week of August, Dave Williams K7HMP out of Stafford saw the VA ARES-VOAD article in the Fredericksburg Free Lance-Star and Dave Minyard discovered a Letter to the Editor he wrote in the Brunswick Times. His work shows that there are many ways to get the word out and we must MUST market ourselves in order to protect our self- interests. It’s not enough to hand out wallpaper to each other; we must honor and thank those who will publicize our efforts. So, while you make friends with local politicians and Emergency Managers, take the time, like Wayne Rash N4 HCR of Lynchburg and Manassas and Dwight Rohr W4SPJ of the Covington, VA area to get to know your local newspaper reporters and editors. Jim Merritt KK4IUH and his Powhatan club got to know Laura McFarland at the Powhatan Today and as a result, an article about their Winter Field Day was placed in that paper and the Richmond Times Dispatch. Just a little effort reaps great rewards. Please send me any published articles . Dave Minyard’s LTE: See next page Virginia ARES update provided Aug 3, 2020 To the Editor: Virginia ARES (Amateur Radio Emergency Service) is pleased to announce that they have been accepted and are now officially members of the Virginia VOAD (Virginia Voluntary Organizations Active in Disaster – https://vavoad.org). -

April 27, 2017 FCC FACT SHEET* Part 95 Personal Radio Service Reform Report and Order - WT Docket No. 10-119 Background: The Commission’s Part 95 Personal Radio Services (PRS) rules address a wide variety of wireless devices that are used by the general public to satisfy personal communications needs. These devices generally use low-power transmitters, communicate over shared radio frequencies, and (with a few exceptions) do not require an individual FCC license for each user. Some common examples of PRS devices include walkie-talkies; radio control toy cars, boats, and planes; hearing assistance devices; CB radios; medical implant devices; and Personal Locator Beacons. This draft Report and Order completes a thorough review of the PRS rules in order to modernize them, remove outdated requirements, and reorganize them to make it easier to find information. As a result of this effort, the rules will become consistent, clear, and concise. What the Rules Would Do: GMRS/FRS Reform. General Mobile Radio Service (GMRS) and Family Radio Service (FRS) devices are both used for personal communications over several miles. The public may be most familiar with FRS walkie-talkies. While GMRS and FRS share spectrum, GMRS provides for greater communications range and requires an FCC license, while FRS does not require a license. The rules will increase the number of communications channels for both GMRS and FRS, expand digital capabilities to GMRS (currently allowed for FRS), and increase the power/range for certain FRS channels to meet consumer demands for longer range communications (while maintaining higher power capabilities for licensed GMRS).
