The Low Frequency Experimenter's

-- by Peter Dodd, G3LDO
Written to meet the needs of amateurs and experimenters who have an interest in low power radio techniques below 200 kHz. Most of the techniques described are targeted at those using the 136 kHz band, but they are also of great interest to readers in New Zealand and Australia with the 183 kHz band and the Lowfers in the USA on 180 kHz.

The bulk of the material in the book comprises contributions from experimenters world wide and covers antennas, propagation, transmitters, special modes and test equipment, and discusses some applications such as communication with caving enthusiasts.

All those interested in exploring the new frontier of the LF bands will welcome this invaluable and unique reference, whether they tend to transmitting or are content just to receive. 112 pages

L F TODAY - RSGB

2nd Edition

A guide to success on 136 and 500kHz
New 2nd Edition
By Mike Dennison, G3XDV and Jim Moritz , M0BMU

The low frequency bands are relatively new to amateur radio. LF Today aims to help you get the most out of operating in this part of the spectrum by passing on the accumulated experience of those who have already found that low frequencies are both challenging and fun.

Based on the experience of the LF experimenters this LF Today provides the reader with a firm knowledge of these frequencies. This edition has been expanded to include the many revisions and updates that reflect the experimental work has been done on the 136kHz band, including gaining a greater understanding of low frequency sky-wave propagation. For the first time there are details of the special research frequencies using low power just above 500kHz. This book includes practical information on antennas, transmitters, receivers and propagation for these experimenters.

Written by the leading authorities on LF, Mike Dennison, G3XDV and Jim Moritz, M0BMU this book is aimed at those who want to try out this fascinating amateur allocation, but it is also of great value to anyone already active on the band. In short, LF Today contains all the information needed to succeed in 136 and 500kHz amateur radio.

International QRP Collection - RSGB

NEW
A compendium of QRP articles from around the world
Compiled and edited by Rev. George Dobbs, G3RJV and Steve Telenius-Lowe, 9M6DXX
QRP (or low power) operating is practiced by many radio amateurs across the globe. Much is published by these QRP enthusiasts detailing great designs, best practice and much more. The authors of the International QRP Collection have scoured the world for the best of these and compiled them for you, into this great scrapbook.
The International QRP Collection contains articles from well known amateur radio magazines such as RadCom, QST, Sprat, Break In and many others, as well as some original material. By far the largest section of the International QRP Collection is that devoted to construction. This will please most QRP enthusiasts, who are also keen equipment builders. To complement this, there are also sections on modifications to QRP equipment, reviews of commercial equipment, QRP theory, and articles on QRP operating. There is certain to be something of interest to all low-power enthusiasts within the pages of this book.
With authors from Europe, Africa, Asia, North America, South America and Oceania, the International QRP Collection is truly an international window on today's QRP construction and operating practices.

Il fai da te di radiotecnica
di Roberto Galletti

Che cos'è una radio? Come funziona? Quali sono i suoi componenti essenziali? Come e perché è possibile ricevere e trasmettere segnali da e per ogni parte del mondo? Quali le tecnologie che ne rendono possibile l'attuazione? E quali i fenomeni fisici che lo consentono? Questo libro è una guida pratica e semplice per chi con l'elettronica non ha ancora preso confidenza. Il testo scorrevole e immediato e le numerosissime figure (oltre 170 tra schemi e disegni), ne rendono immediate le idee e i contenuti.

Amplificatori e alimentatori - Ediradio

L’intento degli autori è stato di raccogliere, in un solo testo, alcune delle più interessanti pubblicazioni di RadioRivista, ma non solo! Il manuale racchiude anche una parte teorica che funge da ripasso delle nozioni che a distanza di tempo possono essere dimenticate.
Infatti, la progettazione e la realizzazione è trattata ampiamente in maniera semplice e con l’ausilio di formule ove necessario.
Gli articoli pubblicati in questo volume sono l’espressione, nel campo degli amplificatori e degli alimentatori, degli studi e delle esperienze di Radioamatori che si dedicano con entusiasmo all’autocostruzione. I progetti presentati sono realizzabili con relativa facilità in quanto supportati da disegni, schemi e fotografie.
Un libro molto utile da cui ricavare spunto per dedicarsi all’autocostruzione nel campo dell’amplificazione e dell’alimentazione ma anche per chi non è pratico e vuole cimentarsi in qualcosa di sicuro funzionamento per provare la soddisfazione di veder realizzato un circuito da lui costruito, seppur suggerito da altri.
Un libro per aumentare le proprie conoscenze, approfondire le nozioni tecniche e contemporaneamente trovare soluzioni a problemi di autocostruzione, sia per chi ha esperienza che per chi è alle prime armi.

Radiotecnica per Radioamatori - C&C

di Nerio Neri

È, questa, la versione completamente riveduta e aggiornata, nonché opportunamente ampliata, di quello che ormai da 20 anni costituisce il testo base per lapreparazione all’esame per il conseguimento della patente di radio operatore. L’attuale revisione, nella sua nuova impostazione, meglio inquadrata l’ampia materia, facendone un vero e proprio vademecum di teoria circuitale sugli argomenti che ne costituiscono il programma, sempre però restando a livello piano e accessibile. La materia risulta inquadrata in 5 ampie parti: Elettrologia ed elettrotecnica, componenti attivi, Elettronica e radiotecnica, Dispositivi per radiocomunicazioni, Misure e strumenti, guidando passo-passo il lettore dall’elettrone all’antenna, sottolineando sempre più sia l’aspetto fisico dei fenomeni che la loro giustificazione matematica, corredando anche gli argomenti più significativi con un certo numero di esercizi esemplificativi. I regolamenti radiantistici e concernenti le radiocomunicazioni, (nonché diverse utili tabelle), completano la trattazione. 308 pagine
