Pocket Prefix for Android

Pocket Prefix has been updated to version 2.4.2 and is available from the Google Play Store, along with an update for pre-installed versions.

Pocket Prefix is an Android app that was designed by Derek G4SWY initially to provide easy offline decoding of Amateur Radio prefixes but with continued development it has evolved into a multi-featured tool for all DXers and shortwave enthusiasts.

Pocket Prefix provides offline lookup of detailed information for callsign prefixes including special event, club, contest and rarely used. It displays DXCC Country, Continent, CQ zone, ITU Zone/Region, DXCC most-wanted rank and UTC offset, as well as whatever geographical and licence detail can be deduced from the prefix.

It uses GPS to obtain your Maidenhead locator (and Worked All Britain square if in UK) and so is able to calculate beam headings and distances from your location to the prefix location.

When connected to the web it integrates real time DX Cluster spot listings (courtesy of DXlite from G7VJR) with easy intelligent filtering and a graphical tuning display with band plan and choice of callsigns or DXCC entity names.

Other features include QRZ.com logon and lookup, Q Codes lookup. Beam heading and distance from your QTH to a Maidenhead locator. On screen UTC. Web search based on country regional detail.

This app for Android is completely free. It has no ads and no in-app purchases.

Map of Italian Ham Radio Repeaters

Andrea Nuzzi IZ8WNH has made available an interactive map of amateur radio repeaters in Italy 

By selecting a place of interest, the application displays the results on both map and a table. The data can be downloaded as a CSV file for programming your transceiver memories using CHIRP or ADMS (for Yaesu radios).

VHF/UHF DX Book Replica Edition

'The VHF/UHF DX Book' was written in the early to mid-1990s by a team of experienced VHF/UHF DXers and equipment developers, in an effort to pass on our knowledge and stimulate further developments.

But eventually the book went out of print, and information of lasting value became trapped on the printed pages.

To keep that information alive for future generations of VHF/UHF DXers, a digital replica of the Second Printing (1995) has now been released as a free download, by kind permission of the copyright owner TR Publishing and its proprietor Trevor Preece.

As with all older books, the challenge for the reader is to separate the parts that are of lasting value from other parts that have become dated. But we make no apology for that; even the outdated parts remain an accurate snapshot of VHF/UHF DXing in its heyday.
