   these activity days proving again that long distance Microwave propagation is   
   not just a Summer Season phenomenon.

   AR MAGAZINE:-   
      
   Hello all, on this, the anniversary of the armistice that ended theKorean War   
   in 1953.   
      
      
   This is Editor-in-Chief of Amateur Radio magazine, Roger Harrison VK2ZRH,   
   with more about Issue 4 now coursing its way through the postal system and   
   across the shelves of selected newsagents throughout Australia.   
      
      
   Having marshalled all those articles on the subject of Antennas and Earths,   
   it would have been remiss of me to leave out something to use them. So, I   
   reviewed a rig thats new to the Australian market bearing a makers name   
   scarcely known here, too.   
      
      
   Its a 28 MHz band rig by Ailunce, boasting full coverage of the 10 metre   
   band, 35 Watts output and four modes to choose from, being SSB-CW-AM and FM.   
      
      
   As a first rig, or just a fun rig, it certainly gives bang for the buck. A   
   neat companion for the 28 MHz vertical antenna featured on the front cover   
   and reviewed inside.   
      
      
   With propagation benefiting from the current high solar activity, the 28 MHz   
   band can be fun territory. Further to that, the Summer and Winter sporadic-E   
   seasons each year maintain the DX excitement in between times.   
      
      
   Dr George Galanis VK3EIP completes his article on What happens after you hit   
   push-to-talk, explaining how we generate electromagnetic waves when using our   
   rigs and antennas.   
      
      
   To extend or update your knowledge of digital technology, we have an article   
   on the	Basics of Delta Modulation, by Elmo Jansz VK7CJ.   
      
      
   Also this issue,  the Your WIA working for you column  covers the Institutes   
   response to the International Amateur Radio Unions proposal to restructure.   
      
      
   But wait! Theres more, yet  the ALARA column, Below 25, Contesting, WestNews,   
   the WIA DX Awards tables  and so on.   
      
      
   More guts. Less gab. Serving hams across Australia since 1933. Proudly   
   produced and printed in Australia.

   The International Amateur Radio Union has announced the passing of   
   David Court EI 3 IO).   
      
   "David was a leading figure in  international  spectrum  management   
   on behalf  of the  amateur service, bringing decades of  technical and   
   regulatory experience  to  his  volunteer work at the highest levels of   
   global telecommunications governance.   
      
   David served on the IARU Region 1 Executive Committee and was a key   
   contributor to  IARU's presence in the  International Telecommunication   
   Union and telecommunication organizations such as CEPT.   
      
   His leadership was particularly critical in  advancing amateur access to   
   the 50MHz band,  culminating in the  successful outcome at  WRC-19,   
   where a 6 meter  allocation  was approved  on a  secondary basis  in   
   many  countries".

   Now to Washington, D.C., where the FCC has approved an experimental license   
   for the satellite of a 5G mobile provider - and the license approves use of   
   some amateur radio frequencies. We have details from Newslines Kent Peterson   
   KCDGY.   
      
      
   AST SpaceMobile, the Texas-based rival of SpaceX, has been approved for an   
   experimental license to test a low-earth orbit satellite that is the   
   prototype for its planned mobile phone connectivity from space.   
      
      
   The US Federal Communications Commission granted the license on Friday, July   
   11th, giving the company the ability to test a satellite that has a   
   phased-array antenna that enables it to function as a cell tower from space.   
   Known as FM1, it is at the centre of the 5G broadband provider's hopes to   
   build a satellite-to-phone internet system. The FCC has assigned the callsign   
   WP2XRX, which expires on July 1st, 2027. A copy of the license online shows   
   that it authorizes experimental operation only on 37.5 GHz-42 GHz, and 2.235   
   GHz, 2.245 GHz for mobile satellite services.   
      
      
   The amateur radio frequencies, 430-440 MHz, also appear on the license. The   
   5G service requested those frequencies to conduct telemetry, tracking, and   
   tele command between ground stations and its satellites. The company seeks   
   FCC approval for operation of 248 low-earth orbit, non-geostationary   
   satellites. Its present license only permits five.   
      
      
   AST SpaceMobile has been developing its network in association with AT&T and   
   Verizon. SpaceX is partnering with T-Mobile.   
      
      
   A copy of the license can be seen using the link to the FCC website that   
   appears in the text version of this week's news.   
      
      
   This is Kent Peterson KCDGY.   
      
   apps.fcc.gov/els/GetAtt.html?id=380200&x=.   
      
   Thanks Kent, this application, from AST & Science requests unprecedented   
   authorization to 430-440 MHz for a constellation totalling 248 satellites   
   to communicate with five ground stations using up to five channels with upto   
   256 kHz bandwidth.   
      
      
   A formal opposition, filed by ARRLs Washington Counsel, asserts that the   
   permission AST seeks to use the 430  440 MHz band should be denied   
   because AST does not demonstrate need for TT&C spectrum beyond that   
   available within existing allocations.   
      
   The comments go on to outline why the application would be non-compliant with   
   the ITU Radio Regulations Treaty.   
      
      
   Reply comments to the application are due by August 5, 2025. ARRL will   
   continue to promote and protect amateur radio spectrum.   
      
      
   News in from Canada is that the delivery of TCA has been delayed due to   
   closure of the magazine's printing company.   
      
   Radio Amateurs of Canada has received the sad news that Maracle Inc   
   publishing company has closed its doors permanently and that the magazine   
   is now being printed by another printer on a temporary basis and that RAC we   
   are in the process of obtaining printing quotes.   
      
      
   51 On Air Transmitters! The Record Breaking Field Day Tactics of W3AO   
      
   Rol Anders K3RA and Frank Donovan W3LPL are the masterminds behind W3AO, the   
   most dominant Field Day station in the United States.   
      
      
   >From their first 4A entry in 1998 to a record-breaking 51A effort, theyve   
   built a machine that blends military-grade precision with community-driven   
   grit. Under the Potomac Valley Radio Club banner, theyve rewritten whats   
   possible during the annual ARRL Field Day shattering records in -   
   wait for it - TWENTY FOUR categories and routinely topping 10,000 QSOs.   
      
   Their story isnt just about towers, yagis, and coax (though theres a   
   literal mile of it). Its about cultivating a culture where even food   
   logistics and porta-loos run with practiced efficiency.   
      
   This years setup, powered by crank-up AB-577 towers and bulletproof   
   generators delivered flawless multi-transmitter operation across the   
   same bandCW, SSB, digital, without a hint of interstation interference.   
   The secret?   
      
   Tip-to-tip antenna alignment and 1,000-foot lines stretching across Maryland   
   school fields.

   A CHALLENGE FOR SOUTH AFRICAN AMATEURS   
      
   In last weekends SARL News Service they pointed out that a foot note   
   to the IARU Region 1 10 MHz band plan states,   
      
   The band segment 10.120 kHz to 10.140 kHz may be used for SSB
