The future of shortwave

 

The future of Shortwave is looking bright as the BBC Shortwave transmissions service of two decades ago is being revisited.

 

In a time where people are distancing themselves and experiencing isolation. Shortwave may just be what the world needs to unite all cultures!

 

People who enjoy shortwave and for those who are interested in shortwave radio something interesting has emerged from the  High Frequency Co-Ordination Conference (HFCC), a non-governmental association.  

 

Due to the fact that many of the old transmitters needed to be replaced or upgraded a decision to revisit the need for shortwave and consideration to re-launch the BBC shortwave broadcast  service (cut 20 years ago) has been undertaken. Modern technology allows greater coverage and lower operating costs, re-energising the enthusiasm for shortwave broadcasting.

 

Even in this high tech world, there are still so many developing and free world countries relying heavily on Shortwave radio. Not everybody in the world has smart phones, broadband, connected cars or enough disposable income.

 

Shortwave defies cultural, religious and geographical barriers, Shortwave is free and unlike most platforms available it can be consumed anonymously.

For some countries, much of their information and media is censored, so receiving updates through shortwave from neighboring countries can be the only source they can access.

 

Many, especially in North Korea which are rated as the second most censored country in the world, tune in to cross border broadcasts despite serious consequences if caught by the Kim Jong-Un regime.

The BBC Shortwave transmission services used to broadcast to most of the world, over time however, many were cut, limiting broadcasts  to larger audiences in Africa and part of Asia. 

Currently, the major shortwave broadcasters are BBC, Voice of America, All India Radio, China Radio International, Radio Japan, Radio Romania, Radio New Zealand, Radio France International, Radio Taiwan International, KBS Korea and Voice of Turkey and many more.

 

Reinstating the previous BBC Broadcasts would mean the world of shortwave could be enjoyed cross culturally again especially in a time where boarders are closed to each other and people are feeling isolated.

 

 “Shortwave is just short of a miracle, actually. When it is beamed at an angle, it hits the ionosphere. A mirror around the Earth and then it falls like a ball at great distances, beyond the horizon. Thus these transmissions reach listeners over large areas, continents and beyond. Two or three high-power transmitters can potentially cover the entire world.”

                                Ruxandra Obreja ( chairman of Digital Radio Mondiale.)

Easily identify shortwave stations

For those of you who have ever been scanning shortwave radio and happened across an interesting station but have no idea what it is or where it is coming from there are a couple of phone apps that can identify what you are listening to.

 

These 2 apps (depending on what type of phone you have) will help listeners identify who they are listening to.. All they need to do is lookup the frequency they are receiving  and these Apps will show what stations are on air at the time. This is an easy way to identify who you are listening to.

 

                                                                                                                                          For Android: Click here

Radio licence applications soars.

Tecsun Radios Australia has set up a Software defined radio (receiver) in Araluen, a rural town in NSW, Australia. It’s a quiet location for radio “noise”, far away from high density population and the accompanying RF noise generated.

You can listen to the Tecsun Radios Australia SDR here.

The SDR itself is called a “KiwiSDR” and is a commercially available unit, costing around $500. The Kiwi SDR compared to others has 2 advantages: (1) it allows the user to observe the entire shortwave spectrum in one screen, and (2) it can easily be connected to the internet to allow remote operation.

Other SDRs only receive a narrow portion of the radio spectrum, and require extra equipment to connect to the internet.

With the Kiwi SDR, it is easy to remotely identify that a signal exists from the “waterfall” display and then accurately tune and receive it.

The SDR is connected to an onmidirectional wideband antenna, so that all signals across the shortwave band can be equally well received (however this is dependant on signal propagation at different times of the day). The antenna itself is a modified Tecsun Radios Australia discone, with some of the radials removed to give the antenna a higher angle of radiation. The central active element has been replaced with a 3 meter spiral wound helical element. This simulates a much longer piece of antenna wire needed for lower frequency reception.

The antenna has been located as far away from man made noise sources as possible, is fed with special double shielded coaxial cable and a variety of matching transformers and attenuators, to ensure local stations do not overload the sensitive “front end” of the SDR. Careful attention has also been paid to the grounding of the antenna.

Because the location is remote and in a bushfire affected area, mains power is supplemented by a diesel generator and UPS.

Connectivity to the www is achieved via a Ka band NBN satellite link.

The Kiwi SDR can be used to receive AM, AM Narrow, USB, LSB, weatherfax, CW (Morse Code) and DRM signals (when a suitable decoder is used).

You can listen to the Tecsun Radios Australia SDR here.

Or, simply logon to the SDR (go to https://sdr.hu/ for a worldwide list), select an SDR located close to the transmission source you’d like to listen to, select AM mode and the desired frequency.

In 2017, the shortwave radio airwaves fell silent with the cessation of Australian domestic and international shortwave radio broadcasts. This was the culmination of withdrawing funding from a variety of Australia Government Departments including the Department of Foreign Affairs and Trade and ultimately the Australian Broadcasting Corporation.

The ABC labeled shortwave radio an antiquated technology and opted instead to reallocate resources and funding to local FM transmissions focused in Papua New Guinea. As a result of this, China promptly and actively moved to fill the Australian Government’s earlier role of broadcasting Shortwave Radio into the Asia Pacific region via the ABC. A large number of the people living in some of the most remote communities of the Pacific Islands actively rely on shortwave radio broadcasts to keep in touch with the world.

Without Shortwave Radio, many individuals are left isolated. The positive impact shortwave radio can have on many individuals in the Asian Pacific region is demonstrated through the example of  Chief Ben Lovo and his family of Bongkil Village on Erromango, Vanuatu, said that “shortwave broadcasts from RNZI during Cyclone Pam, allowed him to warn four villages of the danger and save hundreds of lives.”

Shortwave radio is so effective at providing long range communications because the radio waves bounce off the ionosphere and back down to the ground allowing a single shortwave radio broadcast to be heard thousands of kilometres away from the transmitter. It is because of this that shortwave radio works particularly well distributing signals to the many remote islands throughout the Pacific region, where there is no other means of low cost mass communication.

China, already aware of this and in light of Australia’s withdrawal from shortwave broadcasting, increased their existing broadcasts into the region fully understanding that if shortwave coverage is present, their sphere of influence and subsequent “soft power”would be immediately increased. The notion, that the Chinese immediately adopted the frequencies that the Australian Government, and indeed the ABC cut funding towards, “comes at a time of heightened speculation in Australian media and the commentariat about the motives behind China’s growing influence in the Pacific.”

The growing Chinese interest in the Asia Pacific region has led to the Australian Government,  to conduct a review of the broadcast services available in the region and whether Australia should reintroduce Australian international Shortwave Radio broadcasts.

The Review, will analyse:

  • The coverage and access of existing Australian media services in the Asia Pacific region, including examining whether shortwave radio technology should be used

The review will cover:

  • All media distribution platforms (i.e. Television, radio and online)
  • Commercial, community and publicly funded services and
  • Different types of technologies such as analogue, digital and satellite radio and television services and online services.

Supporters of Shortwave Radio, are encouraged to engage in the review hosted by the Australian Government. Tecsun Radios, as firm believers in the vital service that shortwave provides, believes that this review will act as a catalyst in encouraging Australia, to re-enter the Asian Pacific market in providing the vital service that shortwave allows.

Tecsun, will actively engage in the review process, in the hope that this reinvigorates Australia’s interest in the Pacific region. We firmly believe that shortwave radio through its modern evolution digital radio mondiale (DRM) provide the optimum technology to delivery broadcast style communications to island in the Pacific region.

The review is open until the 3rd of August. You can use the link provided below to add your comments and ‘Have your Say Now’, in regards to re-establishing Australia’s presence in the Asia Pacific region, for shortwave radio broadcasting.
