SDRanywhere

Operate RFSPACE SDRs anywhere in the world
on your Android tablet, Windows, Linux or Mac OS



The SDRanywhere application is an Android app that allows remote operation of an RFSPACE SDR-IQ or CloudSDR radio anywhere in the world. The demodulated audio and waterfall information is compressed and sent to the client application using a low bandwidth internet connection. The upcoming CloudSDR has a built in server and it connects directly into an ethernet jack or WIFI client. It can serve as a remote sensor node or remote RX point. The SDR-IQ requires a computer running the server app.

The server application for the SDR-IQ is part of the Windows RemoteSDRClient project inSourceforge. This client application is open source. The RemoteSDR download also includes a PC, Linux or Max OS client to connect to the SDR-IQ and CloudSDR radios.


Ham band 20 Mt.

The instructions for the RemoteSDRClient and server setup are available here:


The Android application is currently in beta and will expire on February 1, 2014. It is a .APK file for Android 4.0 and newer devices it can be downloaded here:



RFSPACE maintains a Web Server list showing the radios that are publicly available. Any user with the Android or PC clients is welcome to connect.

Radio Free Asia Releases 18th Anniversary QSL



Radio Free Asia (RFA) announces the release of our 18thAnniversary QSL card. RFA’s first broadcast was in Mandarin on September 29, 1996 at 2100 UTC. RFA is a private, nonprofit corporation broadcasting news and information to listeners in Asian countries where full, accurate, and timely news reports are unavailable. Acting as a substitute for indigenous free media, RFA concentrates coverage on events occurring in and/or affecting Burma, Cambodia, Laos, North Korea, the People’s Republic of China, and Vietnam.  RFA does not express editorial opinions but provides news, analysis, commentary, and cultural programming in the languages of the country of broadcast. This is RFA’s 55th QSL design and will be used to confirm all valid RFA reception reports from September 1-December 31, 2014.



Created by Congress in 1994 and incorporated in 1996, RFA broadcasts in Burmese, Cantonese, Khmer, Korean to North Korea, Lao, Mandarin (including the Wu dialect), Vietnamese, Tibetan (Uke, Amdo, and Kham), and Uyghur. RFA strives for accuracy, balance, and fairness in its editorial content. As a ‘surrogate’ broadcaster, RFA provides news and commentary specific to each of its target countries, acting as the free press these countries lack. RFA broadcasts only in local languages and dialects, and most of its broadcasts comprise news of specific local interest.  More information about Radio Free Asia, including our current broadcast frequency schedule, is available at www.rfa.org.

RFA encourages listeners to submit reception reports.  Reception reports are valuable to RFA as they help us evaluate the signal strength and quality of our transmissions. RFA confirms all accurate reception reports by mailing a QSL card to the listener.  RFA welcomes all reception report submissions at http://techweb.rfa.org (follow the QSL REPORTS link) not only from DX’ers, but also from its general listening audience. 

Reception reports are also accepted by email at qsl@rfa.org and by mail to:

            Radio Free Asia
            2025 M. Street NW, Suite 300
            Washington DC 20036

Radio Free Asia - QSL News




Dear friends, We are changing the way we send QSL card information by email for our friends and listeners; we believe this will improve our handling of QSL information and reception reports.  This week we will distribute the press release for our new QSL card design which will be used for all confirmed reception reports from Sep 1 - Dec 31.  

There may be some bumps as we start the new method but we hope you will be patient with us.  As always, please let us know if you want to be removed from our email list. 

Thank you for continued interest in RFA, our programming, and especially for your interest in our QSL cards.   
73.
