 This is Roger Harrison VK2ZRH with a quick story on fast radio bursts

 This weekend, I am attending the Gippsland Technical Conference,
 otherwise known as GippsTech. This annual event comprises
 presentations by amateurs for amateurs, with an emphasis on
 VHF-UHF and microwave technology and techniques, especially for
 weak-signal working. 

 However, my news is about really – really weak signals – radio
 astronomy.

 There has been a lot of effort by the global radio astronomy
 community in studying fast radio bursts since they were discovered
 in 2007. Fast radio bursts last less than a millisecond, making it
 difficult to accurately locate just where they have come from.

 Not only are they weak signals, they dont last long !

 Most are single, one-off bursts, but some are known to repeat.

 Well – finally, an Australian-led international team of astronomers
 has determined the precise location of a powerful one-off burst of
 cosmic radio waves. The phenomenal discovery was made with the
 C S I R O's new Australian Square Kilometre Array Pathfinder radio
 telescope in Western Australia, generally known as ASKAP.

 The galaxy from which the burst originated was then imaged by three
 of the world's largest optical telescopes and the results published
 online on 27 June. 

 Want to know the full story?
 Google “Astronomers make history in a split second”.

 Why am I interested in this? 

 Well, I once wrote a series of articles on “Radio Astronomy for
 Amateurs”, published in Electronics Today International – or,
 E T I to the cognoscenti.

 What will the clickeratti make of this ?

 WIA ANNUAL CONFERENCE 2020

 Call for Presentations
 
 At the WIA Annual Conference in Sydney it was announced that the 2020
 WIA Annual Conference will be held in Hobart on the 8-10 May 2020.

 The theme is Antarctic Gateway and so the tours and visits during the
 weekend all revolve around Antarctica and Radio.

 This is a request for anyone who would be prepared to give a
 presentation on the Saturday afternoon on any aspect of amateur radio,
 Antarctica, radio, electronics, experimentation or all of the above.
 The presentations slots are 30 to 40 minutes in length with 5 to 10
 minutes of questions at the end or throughout the presentation.

 If you have a topic and or presentation or just an idea for one then
 please contact Justin on vk7tw @ wia.org.au 
 




 It is Aidan here with this weeks board comment.

 At the recent WIA Open Forum, held during AGM weekend, it was made
 abundantly clear by the members that "something needed to be done"
 to ensure the survival of the hobby.

 The WIA Board committed to drive a program of change that is intended
 to return our hobby, which some would call "the original electronics
 experimenters club" to its rightful position within our community. 

 For roughly  100 years, (beginning in October, 1933), AR Magazine has
 been a staple for radio and electronic enthusiasts around Australia.
 The results of the 2017 board's survey into Amatuer Radio clearly
 demonstrated that, of those who responded, the publication of a 
 stimulating and relevant journal was of utmost importance.

 When speaking to members regarding AR Magazine during the recent
 AGM one of the matters that was repeatedly raised was the slow shift
 of the journal from being a journal of technical excellence that
 educates others and demonstrates our contribution to society to one
 that was becoming more of a social journal.  One member observed that
 this is not restricted merely to our Journal, and argued that it is
 representative of the hobby migration from one of technical discovery
 to that of a social activity. It should be noted that this view was
 not held by all involved in the discussion with others citing the
 progressive activities of their clubs to educate and cultivate
 tomorrows members.

 It is the view of your Board that the WIA and it's Journal should
 lead, not lag the community and with a vision of delivering, once
 again, Australia's premier radio and electronics journal. I am here
 to ask, on behalf of the Board, and Harry, our recently appointed 
 "Editor in Chief", for your assistance.

 The WIA is looking for contributors for the WIA Magazine.    If you
 have a technical article (whether previously submitted to AR magazine
 or not), a construction project, or you or your employer are involved
 in the design, construction, manufacture or delivery of technology or
 technology based products that you believe would be of interest to
 the radio and electronics experimenters in Australia we would love to
 hear from you.   

 If you can assist, or know someone who can assist, please email
 wiamag@wia.org.au

 The WIA commits to ensuring that submissions are processed promptly
 if they are received in a publishable format, and to advise you 
 should anything else be required. 

 With your help we can once again publish Australia's premier journal 
 for radio and electronics enthusiasts.

 Thats all from me, this is Aidan, VK4APM





 DISCUSSION POINT   

 IEEE article: Is Ham Radio a Hobby, a Utility…or Both? 

 Some think automated radio emails are mucking up the spectrum
 reserved for amateur radio, while others say these new offerings
 provide a useful service.
 
 Julianne Pepitone writes in the IEEE Spectrum magazine: 

 Like many amateur radio fans his age, Ron Kolarik [K0IDT], 71,
 still recalls the “pure magic” of his first ham experience
 nearly 60 years ago. Lately, though, encrypted messages
 have begun to infiltrate the amateur bands in ways that he says
 are antithetical to the spirit of this beloved hobby.

 So Kolarik filed a petition, RM-11831 [PDF], to the U.S. Federal
 Communications Commission proposing a rule change to 
 “Reduce Interference and Add Transparency to Digital Data
 Communications.”  As the proposal makes its way through the FCCs 
 process, it has stirred up heated debate that goes straight to the
 heart of what ham radio is, and ought to be.

 The core questions:
 Should amateur radioand its precious spectrumbe protected purely as
 a hobby, or is it a utility that delivers data traffic?

 Or is it both? And who gets to decide?

 Two Metres: Re-Allocation?

 There is concern – understandably – in the amateur community over
 a French proposal to re-allocate 144 – 146 MHz to the aeronautical
 navigation service to accommodate the growing number of aircraft
 employing new navigation tracking and communication aids.

 Here is a brief summary of what and where this proposal is …

 The French administration have proposed a new primary allocation to
 the aeronautical mobile service in 144 to 146 MHz which is the
 entirety of the amateur two-metre band in ITU Region 1 (Europe,
 the Mid-East and Africa). 

 Their proposal was most recently considered at a meeting in Prague of
 a subcommittee of the Conseil Europeen des Postes et
 Radiocommunication (CEPT). The CEPT comprises 48 European states.

 What is under consideration specifically is that an agenda item to
 this effect be included for the World Radiocommunication Conference 
 tentatively planned for 2023. The WRC-23 agenda will be decided at
 the conclusion of the next WRC which begins October 28th in Egypt.

 The International Amateur Radio Union was present as an observer at
 the Prague meeting and energetically opposed the French proposal.
 In the event, ONLY Germany among the delegates opposed the French
 proposal.

 The issue will now be taken up at a higher level CEPT meeting in
 August. Belgium has apparently joined Germany in opposition.

 Should the number of administrations opposing the French proposal
 reach eight the proposal will fail to move forward.
 The IARU and European amateurs are now actively seeking the support
 of other administrations to oppose this French proposal.

 Formally, the proposal is not on the agenda of any other regional
 groups preparing for WRC-19.

 Over in Canada, their RAC has made known to the regulator that they
 support IARUs opposition to the French proposal and its actions to
 defend amateur radios worldwide primary allocation and that they
 would oppose any similar proposal for re-allocation in Region 2 
 (the Americas).

 The Comisión Interamericana de Telecomunicaciones (CITEL) of the
 Organization of American States will meet in Ottawa mid-August.
 The IARU will again be an observer and RAC will be represented in the
 Canadian delegation.

 Bryan Rawlings VE3QN told RAC members 'This issue is a clear
 illustration of the importance of amateurs and their national
 associations being vigilant and taking part in the regional and
 international regulatory conferences which can determine the fate of
 our most-cherished amateur bands.





 GERMANY

 Microwave Manager addresses Spectrum Summit

 IARU expert and RSGB Microwave Manager Barry Lewis, G 4 SJH presented
 a key address to a panel session on 'Keeping the Spectrum Clean' at
 the 24th Annual Spectrum Summit in Germany that attracted 200
 delegates from 34 countries.

 He said, "The amateur radio community struggles with an ever-growing
 level of electro-magnetic pollution that is crowding in across the
 radio spectrum from the lowest frequencies up into the VHF bands.
 In some frequency ranges, efficient and useful radio communication is
 becoming compromised. Aftermarket regulation and slowly evolving
 standards are struggling to be effective in keeping the spectrum
 clean for all users."





 TO THE MOON AND BACK

 First Ever Contact via Moon Orbiting Transponder on LO-94 links
 Germany to China.

 Daniel, EA4GPZ, has reported on the details of the first contact via
 a lunar orbiting repeater that was accomplished via China's
 DSLWP-B (LO-94) satellite.

 In parallel with solar eclipse testing, the GMSK to JT4G repeater
 onboard DSLWP-B was used to make a QSO between BY2HIT, and
 Reinhard Kuehn DK5LA. This is the first ever Amateur radio QSO made
 through a lunar orbiting repeater.

 Using the GMSK to JT4G repeater is not easy, in terms of the signal
 power needed for the uplink.

 Congratulations to the people at both sides of the QSO, who achieved 
 it a month before DSLWP-B crashes against the lunar surface.

 "The GMSK to JT4G repeater works by sending commands to the satellite
 which embed a 13 character message, using the same frequency and a
 similar protocol to the one used to command the camera and other sat-
 ellite functions. The precise definition of this mode is a 7.8125 baud
 FSK modulation with a shift of 394.53125Hz. Each FSK tone is "spread"
 with a 250 baud GMSK 32 bit syncword. The CCSDS 32 bit syncword is used
 to mark the beginning of a packet, and a Reed-Solomon (64,32) code is
 used for FEC, together with CCSDS scrambling. Such a message takes a
 bit longer than one minute to transmit. The uplink is in the 2m Amateur
 satellite band.

 "The repeater downlink is the usual JT4G downlink of DSLWP-B in the
 70cm Amateur satellite band. The 13 character messages sent in the
 uplink command replace the usual JT4G telemetry, being repeated as
 a free-form JT4G message. In the case of this QSO, the B1 radio at
 436.400MHz was used. This radio was also used to transmit the images
 using GMSK SSDV."

 DENMARK

 IARU attends WPT meeting in Copenhagen

 A further meeting on Wireless Power Transmission was held in
 Copenhagen in week beginning July 1, 2019  

 IARU Region 1 reports that this was a sub-group of CEPT Committee
 SE24 charged with work on a report on generic WPT devices.

 Don Beattie, G3BJ, representing IARU, made input on its projections 
 of harmful emissions from WPT systems, both generic and WPT-EV,
 operating at the existing harmonic emission limits defined by CISPR
 and ITU/CEPT. IARU also reported on tests carried out on small WPT
 devices, (with the full report to be consdered at the next meeting in
 September).

 IARU continues to argue for tighter emission limits on harmonics and 
 other spurious emissions from WPT systems, which have the potential
 to cause sustained harmful interference to incumbent radio services.

 USA - WEST COAST
 
 California Earthquakes Disrupted HF Propagation on West Coast


 British Columbia radio amateur Alex Schwarz, VE7DXW, said that an
 Independence Day magnitude 6.4 earthquake in California and multiple
 aftershocks negatively affected HF propagation on the US west coast.

 Schwarz, who maintains the “RF Seismograph” and has drawn a
 correlation between earthquake activity and HF band conditions, said
 the radio disruption began at around 1600 UTC on July 4, and
 continued into July 5. He said that on July 4, the blackout was total
 except for 20 meters, where conditions were “severely attenuated,”
 VE7DXW said.

 The RF Seismograph also detected the magnitude 7.1 earthquake on
 July 6 in the same vicinity.

 Over the US holiday weekend, Schwarz had reported “a massive
 short-wave radio blackout” on the west coast. “It is not caused by
 the sun (the sun is quiet), but the field lines of the quakes
 themselves,” he said.

 On July 6 the RF Seismograph showed an increase in noise on 80 meters
 some 13 hours beforehand, as well as some propagation changes on 40
 and 30 meters  low before the quake and increasing in its wake.
 Increases in noise on 15 and 10 meters were detected some 10 hours
 before the earthquake, diminishing about 3 hours afterward.
 In addition, noise level and propagation changes on 20 meters some 
 3 hours before the earthquake

 A team of researchers affiliated with several institutions in
 Spain and the U.S. has announced that they have discovered a
 new property of light -- self-torque.

 Their findings have been published in the journal Science.Phys.Org

 Their technique may be used to modulate the orbital angular momentum
 of light in ways very similar to modulating frequencies in
 communications equipment, leading to the development of novel devices
 that make use of manipulating extremely tiny materials.

 Submitting news items

 If you would like to submit news items for possible inclusion in the
 VK1WIA broadcasts, please email your item in text to

 	nationalnews @ wia.org.au  

 and don't JUST send url's links or posters,
 but take the time to pen YOUR contribution. 

 To submit audio read "how to submit items" in the weekly news page on
 http://www.wia.org.au/members/broadcast/contribute/
 
 We would appreciate items no longer than 2 minutes in length as we
 only have a half hour.

 Remember the sooner you submit material the more the likelihood of it
 being broadcast in the very next edition of WIA National News.
 Each item will only be broadcast once, if you want a couple of
 mentions, please submit different slants to keep your event 'fresh'
 and always if the news room is to read your item ---
 write it in the 3rd person.
