Shiplake and the Banks of the Thames
Shiplake and the banks of the Thames Introduction The walk takes us from Shiplake (strictly speaking Shiplake Cross), through Lower Shiplake, along the banks of the Thames as far as Shiplake College and then back to the start. Key points are numbered on the map and correspond to the numbered sections below. Shiplake is a two-village parish. The oldest part is the area known as the village of Shiplake Cross. It is close to the parish church of St. Peter and Paul, Shiplake College (formerly Shiplake Court and farm), the local primary school and the Plowden Arms pub. The newer part, near the river and the station, is Lower Shiplake which is the "commercial centre", with all the shops, a post office etc. The name Shiplake most likely stems from 'stream where sheep are washed‘ (sheeplake) but it has also been suggested that it could be named after the final resting place of a Viking ship (ship loss) as the river was too shallow to navigate above Shiplake. 1) Shiplake Memorial Hall and Institute Shiplake Memorial Hall was built in 1925-6 as the gift of the Mardon family in memory of their son killed in the First World War. It was prominently supported by the Thames Lodge of the Freemasons. It was used as a temporary classroom for evacuees from London during World War Two, as the local primary school was not big enough. In 2013 a complete refurbishment and expansion was undertaken costing £450,000 (almost the same as it cost to build the original). At the western end of Memorial Avenue is a primary school, originally built in 1847 but replaced in 1963 and extended since then. -

This book cannot be expected to please everybody, and it makes no attempt to conciliate those who prefer sentiment to truth, or who allow their reading of historical events to be distorted by present-day controversies, whether ecclesiastical or political. In that respect it tries to live up to the dictum of Samuel Butler that 'he excels most who hits the golden mean most exactly in the middle'. -
Consultation Document Spectrum Allocation Strategy for Other Radio
FOREWORD Botswana Telecommunications Authority (BTA) is mandated by the Telecommunication Act, 1996 [No. 15 of 1996] to ensure the rational use of the radio frequency spectrum in Botswana. The BTA assisted by the Teleplan AS from Norway in association with ICT Consultants (Pty) Ltd from Botswana, is in the process of developing a comprehensive Spectrum Management Strategy. The spectrum management strategy has the following components: • Review the current national radio frequency plan; • Develop a spectrum allocation strategy for various radio services; • Develop a spectrum licensing policy for various frequency bands; and • Develop a spectrum pricing policy In January 2007, the BTA issued a consultation document for radio services dealing with preliminary views and recommendations relating to high demand spectrum . A workshop was held on 14 – 15 February 2007, during which the consultation document was presented and comments/input received from stakeholders. The consultation process for the high demand spectrum has been finalised and the BTA has already communicated it to the industry stakeholders. This consultation document contains information and recommendations on other radio services that were not included in the first round of consultation. The document summarises the key findings from technology reviews, analysis of regional radio regulations, frequency plans (national, regional and international) and available radio equipment.

LONG-WAVE AND MEDIUM-WAVE PROPAGATION The general purpose of this Supplement is to explain the main features of propagation at low and medium frequencies i.e. 30-3000 kc/s, and in particular in the bands used for broadcasting viz. 150-285 kc/s and 525-1605 kc/s. In these bands, the signal at the receiver may have two components: they are (a) a ground wave, i.e. one that follows ground contours (b) an ionspheric wave (sky wave) which is reflected from an ionised layer under certain conditions. In the vicinity of the transmitter, the ground wave is the predominant component, and for domestic broadcasting, the service ideally would be provided by the ground wave only. In fact the limit to the service area is often set by interference from the sky wave. -
WBU Radio Guide
FOREWORD The purpose of the Digital Radio Guide is to help engineers and managers in the radio broadcast community understand options for digital radio systems available in 2019. The guide covers systems used for transmission in different media, but not for programme production. The in-depth technical descriptions of the systems are available from the proponent organisations and their websites listed in the appendices. The choice of the appropriate system is the responsibility of the broadcaster or national regulator who should take into account the various technical, commercial and legal factors relevant to the application. We are grateful to the many organisations and consortia whose systems and services are featured in the guide for providing the updates for this latest edition. In particular, our thanks go to the following organisations: European Broadcasting Union (EBU) North American Broadcasters Association (NABA) Digital Radio Mondiale (DRM) HD Radio WorldDAB Forum Amal Punchihewa Former Vice-Chairman World Broadcasting Unions - Technical Committee April 2019 2 TABLE OF CONTENTS INTRODUCTION .......................................................................................................................................... 5 WHAT IS DIGITAL RADIO? ....................................................................................................................... 7 WHY DIGITAL RADIO? .............................................................................................................................. 9 TERRESTRIAL -
Chapter 1 Background of the Project
CHAPTER 1 BACKGROUND OF THE PROJECT CHAPTER 1 BACKGROUND OF THE PROJECT Currently, the radio transmitting station of MRTV is obliged to operate the transmitter at about half load of their capacities. This is due to such backgrounds as superannuation of equipments, shortage of spare parts, and increase of operation and maintenance cost. As the result, the broadcasting service area has contracted quickly each year (For the current service area, refer to Appendix-6(4) “Estimation of Project Effects”). Especially, transmission to the remote area cannot be fully performed in satisfactory and the means of information distribution towards the nomads is being lost. In order to cope with such situation, the Government of Mongolia selected three (3) stations (Ulaanbaatar, Altai, and Murun) among the existing seven (7) radio transmitting stations as for the Project objective location. The Government of Mongolia expects to restore the ratio of service area to the whole country up to 93% by installing a new 50kW transmitting system to Ulaanbaatar Transmitting Station, and 10kW transmitting system to Altai and Murun Transmitting Stations. In order to procure and install the above-mentioned equipments, the Government of Mongolia requested the Government of Japan for the assistance through Japanese Grant Aid. 1 - 1 CHAPTER 2 CONTENTS OF THE PROJECT CHAPTER 2 CONTENTS OF THE PROJECT 2-1 Basic Concept of the Project At the existing radio transmitting stations, some transmitters have been forced to stop operation due to technical failures, and, in other cases, superannuation of transmitters are advancing near the life limit of the transmitters. Furthermore, it was obliged to reduce the power output to nearly half of normal operation due to shortage of the spare parts and increase of operation and maintenance cost. -
