The purpose of this blog is to gather, aggregate, summarize and preserve the colorful stories that make the American Radio Relay League’s DXCC program the fascinating program that it is. First post: KH5K – The Kingman Reef Mystery! LINK

Astrobiology and the Search for Extraterrestrial Life
Learn about the origin and evolution of life and the search for life beyond the Earth.
Over two thousand years ago, the ancient Greeks wondered if other worlds were habitable. In the coming years this question will be experimentally tested. This course is an introduction to astrobiology. It explores the origin and evolution of life on the Earth and its potential to exist elsewhere. Astrobiology addresses compelling questions of wide interest such as: How did life originate on the Earth? Is this an inevitable process and is life common across the Universe? Astrobiology is an interdisciplinary science that bridges fields as diverse as astrophysics, biology, geosciences and chemistry.

Astrobiology is an interdisciplinary science that bridges fields as diverse as astrophysics, biology, geosciences and chemistry.
In this course we will explore what we know about life’s ability to live in extreme environments on the Earth, we will look at different hypotheses for how it originated. We will look at some of the missions to search for life in our own Solar System and on planets orbiting distant stars. We will discuss some of the extreme environments on the Earth that help us understand the limits of life and how life has adapted to cope with extremes. We will explore the possibility of intelligent alien life and some of the implications of its detection. The course will provide a foundation in astrobiology and introduce students to concepts in a diversity of scientific fields.

What is WRTH?
What is WRTH?
World Radio TV Handbook or WRTH is now in its 66th year. It is the most accurate and complete guide to the world of radio on LW, MW, SW and FM, available in any form.
It is divided into the following sections
Features - This section is in full colour and contains reviews of receivers and ancillary equipment, articles on topical issues such as digital radio, interviews with broadcasters, reception conditions, colour maps showing the location of SW transmitters, and other topics of interest to Listeners and DXers.
National Radio - This section covers the world's domestic radio services. The listings are by country and include all stations broadcasting on LW, MW and SW, and most stations broadcasting on FM, together with contact details.
International Radio - Full details of all broadcasters transmitting internationally are given in this section and are listed by country. The schedules shown are the 'B' or 'winter' SW frequencies as supplied by the broadcasters and confirmed by monitoring, together with any LW or MW frequencies used. It also contains a sub-section showing Clandestine and Other Target Broadcasters arranged by target country. The 'A' or 'summer' schedules, along with updates to broadcaster details, are available as a pdf download from this website in May each year.
Please note - International broadcast SW frequencies change twice a year. The 'B' season comes into effect at the end of October each year and the 'A' season at the end of March. It typically takes 4-6 weeks after the start of the season for the broadcasters to settle on the final frequencies they will use, although changes do continue to be made. We monitor all the frequencies and changes before releasing our information.
Frequency Lists - This section contains MW frequency lists grouped by frequency within regions, lists of all international and domestic SW broadcasts in frequency order, and international SW broadcasts in English, French, German, Portuguese and Spanish, and DRM transmissions shown by UTC.
Television - The TV section has details of the main terrestrial national broadcasters, large regional networks, and some local stations, arranged alphabetically by country.
Reference - This section has tables and listings of: International and Domestic Transmitter sites, Standard Time and Frequency Transmissions, DX Club information, International Organisations, and other essential information.

SkyCube: The First Satellite Launched by You!
Southern Stars Group, LLC, maker of the SkySafari astronomy apps for iOS, Android, and Mac OS X, is developing a nano-satellite as the focus for a global education and public outreach campaign.
This satellite, called SkyCube, is a 10x10x10 cm "1U" CubeSat intended for launch as a secondary payload on a SpaceX Falcon 9 rocket in Q1 2013. The CubeSat will take low-resolution images of the Earth, broadcast simple messages uploaded by sponsors, and deploy a 3-meter reflective balloon to make itself optically visible to observers on the ground.
Sponsorship opportunities begin at $1, and are open to anyone with a smartphone or web browser. Sponsors may follow the satellite in the sky, upload messages for it to re-broadcast, and request Earth images from the satellite, using their smartphone or browser. Southern Stars will develop server infrastructure and mobile/web apps for sponsors to follow the mission.
The mission will utilize a 915 MHz CubeSat ground station communication network operated by the US Navy, the Boeing Corporation, and Utah State University. During ground station passes, the satellite will transmit images to the network, which are then forwarded via internet to sponsors who have requested them. The satellite will also broadcast sponsors' messages every 10 seconds as data pings - "tweets from space" - detectable to anyone with inexpensive (sub-$200) amateur radio equipment. LINK

Interface for Android Smartphones to Yeasu
Wolphi-Link is an Android Smartphone to Ham Radio interface similar to the interface shown in the QST 5/2011 article. Wolphi-Link works with DroidSSTV, DroidPSK, DroidRTTY and Morse Decoder. It will work with radio’s which don’t have a VOX. “Audio in” and “Audio out” levels are adjustable. The interface connects with a 4 pin 3.5mm (both ends) to the Android Device and with a 6 pin Mini DIN (both ends) to the FT817, FT857 or FT897. The interface should work with other radios as well but the cable needs to be customized. For customized cables please contact us at info@wolphi.com.

Fly your name on F-1 CubeSat!
.jpg)
We have sent F-1 CubeSat out to Japan for integration with HII-B rocket and preparation for launch. Thank you for your interest and support! As there are many people who still want to fly their names and messages to space, we will continue to collect your names and will fly them on the next flight opportunity (as soon as 2013). To the stars! FSpace team. LINK
