White space between TV signals could save lives at sea.

Source:  Southgate Amateur Radio Club.

Russ Roberts's insight:

According to the BBC, the leftover white space between TV signals is raising the hope of saving lives at sea and providing broadband for remote communities.  Coast Guard stations in the UK have been using the same VHF technologies for years, with coverage problems created the line-of-sight properties of the VHF marine bands.  Jeremy Blake, a coxswain of the Freshwater Independent lifeboat group, tells the BBC, the technology works fairly well , "but we're still limited by line of sight...we can only have one-way communication at a time, and if someone else is talking on the radio that will drown us out if they've got a stronger signal."  That situation will change shortly as the lifeboat group has been an active participant of a new technology that supporters say could not only save lives but bring superfast broadband to rural communities that so far have been cut off from the information age."  The new technology uses something called "White Space" and takes advantage of unused parts of the spectrum reserved for television transmissions.  Thanks to Stephen (G7VFY) for the story.  For details, visit http://www.bbc.co.uk/news/technology-28957172. ; Aloha de Russ (KH6JRM).

Japanese asteroid mission to carry Amateur Radio.

Source:  Southgate Amateur Radio Club.

Russ Roberts's insight:

A Japanese news report says the asteroid mission Hayabusa 2, planned for a December 2014 launch, will carry  the amateur radio satellite Abyss 2 (Shin'en 2).  The small polyhedron satellite was built by students at Kyushu Institute of Technology and carries a Mode 3 linear transponder for amateur radio communications along with CW and WSJT beacons. Shin'en 2 will have an elliptical orbit around the Sun and will journey through space between Venus and Mars.  Another amateur radio satellite known as ASTSAT2: DESPATCH is also on the launch.  Shin'en 2's IARU coordinated frequencies include:

 

437.505 MHz CW beacon; 437.385 MHz WSJT telemetry; an inverting SSB/CW transponder (145.940-145.960 MHz uplink LSB and 435.280-435.260 MHz downlink USB.  Aloha de Russ (KH6JRM).

Graphene as the Next Great Miracle Material for Space | The Commercial Space Blog

Graphene as the Next Great Miracle Material for Space | The Commercial Space Blog | KH6JRM's Amateur Radio Blog | Scoop.it

On August 20th, Ottawa-based Grafoid Inc, a company involved in the research, development and production of graphene, opened a 225,000 square foot production facility in Kingston, Ontario. The move has Canada positioned to become a world leader in the production of the much-hyped super-material, with effects on many industries, not the least of which is aerospace.


Via Stratocumulus
Russ Roberts's insight:

This Ottawa-based company has just opened a 225,000 square-foot graphene facility, which could make Grafoid, Inc. a major player in the production of this material.  Graphene will have a tremendous impact on the aerospace and communications industries.  Graphene will also affect the type of amateur radio equipment we buy in the future.  According to Grafoid, Inc. graphene will replace silicon in microcircuits and computer chips.  The graphene chips will be smaller, use less power, and could be used in sensor displays and solar batteries.  Our equipment is about to get smaller and lighter.  Interesting development.  Aloha de Russ (KH6JRM).

Race to Build NASA Space Taxi Down to the Wire | DNews

Race to Build NASA Space Taxi Down to the Wire | DNews | KH6JRM's Amateur Radio Blog | Scoop.it

A three-way race to build a commercially operated spaceship to shuttle astronauts -- and other paying customers -- to and from low-Earth orbit is close the finish line, with NASA aiming to award development and flight service contracts as early as next week.

 

So far, two companies favoring capsule designs -- Boeing and Space Exploration Technologies, or SpaceX -- have won the lion’s share of NASA’s Commercial Crew program funds. The effort, which began in 2010, is intended to provide a U.S. alternative for flying crews to the International Space Station, which orbits about 260 miles above Earth.

 


Via Stratocumulus
Russ Roberts's insight:

The so-called "Space Taxi" is an effort to cut reliance on Russian launch vehicles to supply the International Space Station orbiting about 260 miles above Earth.  So far, Space Exploration Technologies (SpaceX) and Boeing have garnered most of the NASA contracts to develop a commercial crew program.  It's about time we developed our own support system and became more self-sufficient in launch and resupply vehicles.  If the cost of launches can be reduced, the U.S. could attract more space customers from the world of business, education, and even amateur radio (i.e. AMSAT).  Aloha de Russ (KH6JRM).

Ham radio equipment for base and mobile operation

Tom Fuszard's Business Builder (Ham radio equipment for base and mobile operation http://t.co/CJoIDApH6j)
Russ Roberts's insight:

Don't let the lack of a tower or an expensive transceiver stop you from enjoying amateur radio.  Even a simple rig and a basic antenna can do wonders for your station if they'r e installed carefully. In Tom Fuzzard's essay, he describes the very simple station  he has assembled:  a Kenwood 820 HF transceiver, basic power supply, a power/swr meter, a telegraph key, and a Butternut 6V vertical connected to about 80 radials.  His 2 meter mobile activity is conducted through a Radio Shack HTX-252 transceiver connected to a 5/8 wavelength mag mount antenna.  With this arrangement, Tom says he works " a number of HF bands without expending a lot of money or disrupting the natural beauty around our cabin."  Keep it simple and have a lot of fun for very little money.  Aloha de Russ (KH6JRM).

US-to-VK Transpacific Reception on 630 Meters Reported
ARRL
A radio amateur and medium-frequency (MF) experimenter in Australia has received a 630 meter (475.62 kHz) transmission from a radio amateur and Part 5 Experimental operator in Texas.
Russ Roberts's insight:

The 630 meter band is providing lots of excitement these days.  Take the case of an Australian ham who received the weak 630 meter signal from a Texas amateur radio operator.  John Langridge (KD5NJD), who holds a part 5 Experimental License (WG2XIQ) said the reception of his WSPR signal by Australian ham Davide Isele (VK2DDI) was a "huge surprise."  While the 8,710 mile distance between the two stations is not a record, "It does represent the sorts of accomplishments that the amateur radio community in the U.S. could enjoy if a band at 472-479 kHz ever becomes a reality."  Isele's antenna is fairly modest:  "a 30 meter thin, galvanized iron vertical wire, strung between a ground rod and a high tree branch for receiving on 630 meters...it has no radials and no antenna tuner." This slice of the rf spectrum just below the standard AM broadcast band has some intriguing possibilities.  Aloha de Russ (KH6JRM).

The program "aims to convey the genuine human drama behind the invention which saved the nation in the Battle of Britain."  Just a note:  Overseas viewers who see the program via the internet may need a UK-based proxy server.  After 04 September 2014, the program will be available for internet broadcast at http://www.bbc.co.uk/programmes/b04gnhv7. ; This sounds like a fascinating program.  Aloha de Russ (KH6JRM).

The U.S. Fish and Wildlife Service has agreed to allow an amateur radio operation from Navassa National Wildlife Refuge (KP1).  The operation will occur within the next 18 months and will be coordinated with the USFWS work flow.  During the past year, the KP1-5 Project has worked with the various levels of the Fish and Wildlife Service to get the operation underway.  The team reports that Wildlife officials have been receptive to the idea of an amateur radio presence on the protected island.  According to DXpedition members,"We have been treated with sincere interest and respect and believe that amateur radio operations may no be viewed as partners and not adversaries."
