World's largest antenna



China is building the world's biggest radio telescope that's the equivalent of 30 football pitches so it can ‘listen to the UNIVERSE’

  • Construction for the telescope started March 2011 and should finish 2016
  • It will be able to collect radio signals beyond our own solar system
  • The astronomy project cost approximately 1.2 billion Yuan  -£120 million
  • China is building the world’s largest radio telescope in Guizhou province, south west China.
    Construction for the Five hundred metre Aperture Spherical Telescope, shortened to FAST, started in March 2011. The project is now expect to be completed by September 2016.
    The gigantic radio telescope will cost approximately 1.2 billion Yuan (£120 million), making it the biggest astronomy project China has ever had. 
    It will allow scientists to get weaker radio signals from outer space, even further than our solar system.
  •   
  •  Gigantic radio telescope: Scientists told local residents that the telescope can reach aliens in outer space. It will reach outside the solar system
  •  
  •  
  •  Construction: It takes more than five years to build the world's biggest single-aperture radio telescope. It's on schedule for completion in 2016
  •  
  •  Location: Scientists scouted more than 30 locations until they landed on the Dawodang Depression, a natural depression in the landscape
  •  
  •  Location: Scientists scouted more than 30 locations until they landed on the Dawodang Depression, a natural depression in the landscape
 New science: physicists say the data can help prove Einstein’s relativity theory once more data of gravitational waves can be retrieved

  •  The Arecibo Observatory in Puerto Rico built in 1963 will lose its title as the largest radio telescope on earth when FAST is completed in 2016
  •  
  •  The Arecibo Observatory in Puerto Rico built in 1963 will lose its title as the largest radio telescope on earth when FAST is completed in 2016
 Every reflective panel is controlled by cables to ensure radio signals can be recorded from every angle. There will be 4,450 panels altogether

  •  
    The telescope is made up of 4,450 reflective panels. The size of the dish will be about thirty football pitches.
    Cables are attached to every reflective panels to control its coordinates.
    The intricate design allows scientists to shift the dish to receive radio signals from different angles.

     River basin: The telescope is built in a natural depression, lowering the cost which is estimated to be 1.2 billion Yuan (£120 million) in total

 The Arecibo Observatory in Puerto Rico will lose its title as the largest single aperture radio telescope ever constructed.

 As big as thirty football pitches, the radio telescope is expected to get data from outside our solar system. Here it's in early stages of the build

 The unknown: Data retrieved from the telescope will help scientists to understand the universe better. It's especially useful for  astronomers

FAST is built in the Dawodang depression in Guizhou Province.
The natural landscape provides the perfect size and shape for the construction of the telescope. The ground also provides enough support for the gigantic telescope. 
The porous soil forms an underground drainage system that protects the telescope.
With only one town in the 12 miles radius, the Dawodang depression is extremely isolated from magnetic disruptions.
The remoteness of the location also protects the surrounding landscape from any damage.

 Enormous: It will take up to 40 minutes to walk around the telescope which measures more than 1 mile in diameter and spans 30 football pitches

EMI Filter

  EMI Filter for HamRadio. Used the old computer EMI filter. You just have a well-shielded it, and this been achieved with the old box of brass.

       In this project I am using  DELTA ELECTRONICS,INC  Emi Filetr ,model ME42- 2Amp.



 An EMI filter, or electromagnetic interference filter, is an electronic passive device which is used in order to suppress conducted interference that is present on a signal or power line. EMI filters can be used to suppress interference that is generated by the device or by other equipment in order make a device more immune to electromagnetic interference signals present in the environment. Most EMI filters consist of components that suppress differential and common mode interference.

2m GP Antenna - Cheap !


                                           
                                                          144MHz. GP by  9A7PJT


This is very inexpensive GP Antenna for 2m band. Material for making antenne is,
One Conector S0-239
4X50cm AL. rods of 2.8mm
1X50cm Copper rod 2.8mm
4 couplings for creeping cables


NOTE - you can use 3mm rods - not critical .

Simply connect coupling with a screw on its SO conector and tighten. At the other end putting AL rods, tighten and bend at an angle of 45 °.
In the radiating element, use a copper rod, but also we can use and Al. rod.

The recommended length for the frequency 145.MHz. are
radials 50cm
radiating element 49.5cm

Length is not critical, and we can leave the elements a little longer. By connecting antenne on the SWR meter can is easily adjusted to 1: 1.1 to 1.2. SWR. Just
 cut the elements a few mm.
 
This antenna is not of sufficient strength to withstand high winds, but as a backup, portable or balcony antenna will be very useful. I recommend the power up to 50W FM.

BaoFeng Buys Tokyo High Power Labs !

                                                           Unfortunately

                                 HOAX HOAX HOAX HOAX HOAX HOAX 


Quietly, without much fanfare, BaoFeng (the marketing name for PoFung Technologies) has purchased the remaining assets from the holding administrator representing Tokyo High Power Labs.
This acquisition, completed just before the end of 2014, signals the entry of BaoFeng into the HF radio market.  This was discussed in detail on QRZ.
RUMORED NEW PRODUCTS
In recent weeks, Factual Amateur Radio Technology Services have learned of a product roadmap for both amplifiers and a new HF transceiver.  We’re still gathering details, but what we’ve learned so far includes:
  • Three New HF Amplifiers, modeled after Tokyo High Power Labs models.
  • Three New HF Transceivers, with features to delight even the most critical of operators
  • A new remote base protocol
Details are still a little sketchy, but the rumored HF Transceivers are reportedly being labeled:
  • BaoFeng Hurricane (SDR with knobs, 250 watt all band transceiver)
  • BaoFeng Tornado (SDR with knobs, 400 watt all band transceiver)
  • BaoFeng Tsunami (SDR no front panel, 100 watt all band transceiver)



IMG_0602


KILLER PRICING
The rumored pricing suggests BaoFeng intends to dominate the HF Transceiver market in a similar fashion that they have supplanted the VHF and UHF handheld world.  We could not verify at this moment, but the suggested retail price for the Tsunami is $180.00 US!

MORE DETAILS TO COME
Watch this site for further information and potentially some prototype photos!

Norway to switch off FM in 2017 ? !







Within two years from now, the shutdown of national FM-networks begins in Norway. The switchover will begin in the North and will be implemented region by region.




Thursday, the Ministry of Culture announced a national FM-switch off, to complete the transition to digital radio. Norway is making an historical move into a new radio era, being the first country in the world to decide upon an analogue switch-off for all major radio channels. With DAB and digital radio, listeners will be provided with more radio channels and greater diversity in content.
Thor Gjermund Eriksen, head of NRK, says:
- This is an important day for everyone who loves radio. The minister`s decision allows us to concentrate our resources even more upon what is most important, namely to create high quality and diverse radio-content to our listeners.
The DAB-coverage in Norway now exceeds FM-coverage. DAB provides Norway with 22 national channels, as opposed to five channels transmitting nationwide on FM.
Switch-off begins 11th January 2017
The decision gives Norwegians a final date for the transition to digital radio, a process persisting for several years. Trygve Rønningen , CEO and editor in chief P4, says:
- We can finally complete the work that has been on-going for many years. This is the best solution for all listeners throughout Norway, as they now have a better radio.
Switch-off starts in Nordland county 11th January 2017 and ends with the northernmost counties Troms and Finnmark 13.12 2017.
Coordintated
NRK, P4 Group and SBS Radio will turn off all its FM broadcasts simultaneously in two of six regions. In four regions however, NRK Radio will lead the way in FM-switch off. Lasse Kokvik , CEO of SBS Radio says:
- The national radio industry have agreed upon a rapid and coordinated plan for the transition, with considerations taken on not giving unreasonable competitive advantages through FM-closing.
Look to Norway
Today’s decision makes Norway the first country in the world to set a final date for FM-switch off. Several countries in Europe and Southeast Asia, however, are in similar processes, choosing DAB-technology as the backbone of future radio distribution.
Ole Jørgen Torvmark , CEO of Digital Radio Norway says:
- The White Paper from 2011 and a unique collaboration between the radio industry is the main reason why Norway is far ahead in the transition to digital radio. Many countries are now looking to Norway to learn.
Ensures a long life for radio
Radio on digital platforms ensures the radio media a long life for years to come. The Radio Industry is better equipped to evolve with listener`s needs and are thus better enabled to adopt to the ever changing patterns of media consumption.
Norway began the transition to DAB in 1995. In recent years two national and several local DAB-networks has been established. 56 per cent of radio listeners use digital radio every day. 55 per cent of households have at least one DAB radio, according to Digitalradio survey by TNS Gallup, continuously measuring the Norwegian`s digital radio habits.

Link to the announcement


Background
Norway is in a transition from analogue to digital radio for all national channels and some local channels. Digital radio expands radio reach and multiplies the number of national channels. More than 90 per cent of the population can now listen to 22 national radio channels. The national DAB networks have equally high and partly higher population coverage than national FM networks. DAB coverage along roads is generally better than FM-coverage .

STATS FOR DIGITAL RADIO IN NORWAY *
- 56 % of radio listeners use digital radio daily
- 44 % of listeners only use FM radio daily
- 20 % of private cars are equipped with DAB radio
- 55 % of all Norwegian households have at least one DAB radio.
-  7.9 million radio sets will be affected by FM-extinction. FM radios can be upgraded or recycled.
* Digital radio survey , TNS Gallup 2015
DAB COVERAGE
NRK: at least 99,5 % coverage on DAB
Commercial radio: 92.8 % coverage on DAB
Community radio: 50 % DAB coverage on DAB
DAB-covarage on roads are generally higher than on FM. All FM-transmitters in tunnels will be replaced with DAB.

World Amateur Radio Day 2015






Every April 18, radio amateurs worldwide take to the airwaves in celebration of World Amateur Radio Day. It was on that day in 1925 that the International Amateur Radio Union was formed in Paris.

Amateur Radio experimenters were the first to discover that the short wave spectrum — far from being a wasteland — could support worldwide propagation. In the rush to use these shorter wavelengths, Amateur Radio was “in grave danger of being pushed aside,” the IARU’s history has noted. Amateur Radio pioneers met in Paris in 1925 and created the IARU to support Amateur Radio worldwide.

Just two years later, at the International Radiotelegraph Conference, Amateur Radio gained the allocations still recognized today — 160, 80, 40, 20, and 10 meters. 
Since its founding, the IARU has worked tirelessly to defend and expand the frequency allocations for Amateur Radio. Thanks to the support of enlightened administrations in every part of the globe, radio amateurs are now able to experiment and communicate in frequency bands strategically located throughout the radio spectrum.  From the 25 countries that formed the IARU in 1925, the IARU has grown to include 160 member-societies in three regions. IARU Region 1 includes Europe, Africa, the Middle East, and Northern Asia. Region 2 covers the Americas, and Region 3 is comprised of Australia, New Zealand, the Pacific island nations, and most of Asia. The International Telecommunication Union (ITU) has recognized the IARU as representing the interests of Amateur Radio.

Today, Amateur Radio is more popular than ever, with over 3,000,000 licensed operators!

World Amateur Radio Day is the day when IARU Member-Societies can show our capabilities to the public and enjoy global friendship with other Amateurs worldwide.

We have provided a poster for World Amateur Radio Day 2015.  Any club may download it and use it to promote WARD in their area.  The poster comes in two sizes: 61cm x 91cm and a small (A4) flyer.

Groups should promote their WARD activity on social media by using the hash tag #WARD2015 on Twitter and Facebook. IARU will list all WARD activities on this page. To have your WARD activity listed, send an email to ARRL  Public Relations Manager Sean Kutzko, KX9X.

April 18 is the day for all of Amateur Radio to celebrate and tell the world about the science we can help teach, the community service we can provide and the fun we have.

We hope you will join in the fun and education that is World Amateur Radio Day!
