Remote Controlled Short-Wave Receiver

By using a web page, remote control of a short-wave receiver located in the University of Twente, Netherlands can be achieved.

In contrast to other web-controlled receivers, this receiver can be tuned by multiple users simultaneously, thanks to the use of Software-Defined Radio.

This site, which in 2008 was the very first WebSDR site ever, was finally reactivated in July 2012 after an interruption of more than 1.5 years.

ARRL Partnership Added to RFinder

The ARRL has established an agreement with RFinder, the creator of a web and app-based directory of Amateur Radio repeaters worldwide, to be its preferred online resource of repeater frequencies.

RFinder is a steadily growing worldwide repeater directory with over 50,000 repeater listings in over 170 countries. An annual $9.99 subscription to RFinder provides access to repeater data through its collection of apps for Android and Apple devices, and from nearly any web browser.

The RFinder team is honored to be ARRL’s partner, providing the very latest online repeater information and directory technology for radio amateurs in the United States. We look forward to working with ARRL to make RFinder even better for US hams.
— Bob Greenberg, W2CYK, creator of RFinder — The Worldwide Repeater Directory.

With one subscription, users have access to repeater data worldwide from computing devices on Windows, Mac, Linux, Android, Apple iOS, and popular GPS systems. A growing list of third-party memory programming applications support radio programming. RFinder provides integrated support for EchoLink on Android and iPhone, allowing users a one-click connection to repeaters worldwide from the directory.

ARRL will receive a portion of each annual subscription to RFinder. 

US radio amateurs who subscribe to RFinder will have online access to its entire worldwide directory while supporting ARRL.

ARRL will discontinue its own products that had supported digital listings of repeater data including the TravelPlus for Repeaters™ software and its own apps. ARRL is working with RFinder on a plan to migrate existing ARRL app users to RFinder, in order to support remaining subscription terms.

“Rest assured that the printed ARRL Repeater Directory, updated and published each year, will continue to be produced,” said ARRL Marketing Manager Bob Inderbitzen, NQ1R. Inderbitzen explained that The ARRL Repeater Directory, available in pocket-sized and spiral bound desktop editions, is especially popular with new radio amateurs, mobile and portable operators, and public service volunteers who rely on the printed copies when they are offline and on the go.

ARRL’s source of repeater data for The ARRL Repeater Directory is voluntarily contributed information from repeater owners and frequency coordinators in the US and Canada. RFinder, on the other hand, assembles its data from worldwide sources, including repeater owners, national and regional coordinating bodies, and carefully reviewed crowd-sourced contributions. RFinder uses dynamic data, allowing users to access listings that regularly reflect new, updated, revised, and deleted information.
