     -------------------------------------------------------------------   
                                                                           
   World Amateur Radio Day is April 18                                     
                                                                           
   ARRL wishes all of our members and friends a very happy World Amateur   
   Radio Day, Sunday, April 18! Join us in celebrating the global          
   community of radio amateurs who explore, develop, and enjoy radio       
   communication. Hiram Percy Maxim Memorial Station W1AW will be on the   
   air on April 18 from ARRL Headquarters in Connecticut. World Amateur    
   Radio Day celebrates the 1925 founding of the International Amateur     
   Radio Union (IARU), which has chosen "Amateur Radio: Home but Never     
   Alone" as its theme for this year's anniversary.                        
                                                                           
     -------------------------------------------------------------------   
                                                                           
   Updated Radio Frequency Exposure Rules Become Effective on May 3        
                                                                           
   The FCC has announced that rule changes detailed in a lengthy 2019      
   Report and Order (R&O) governing RF exposure standards go into effect   
   on May 3, 2021. The new rules do not change existing RF exposure (RFE)  
   limits but do require that stations in all services, including amateur  
   radio, be evaluated against existing limits, unless they are exempted.  
   For stations already in place, that evaluation must be completed by May 
   3, 2023. After May 3 of this year, any new station, or any existing     
   station modified in a way that's likely to change its RFE profile --    
   such as different antennas or placement, or greater power -- will need  
   to conduct an evaluation by the date of activation or change.           
                                                                           
   "In the RF Report and Order, the Commission anticipated that few        
   parties would have to conduct reevaluations under the new rules and     
   that such evaluations will be relatively straightforward," the FCC said 
   in an April 2 Public Notice. "It nevertheless adopted a 2-year period   
   for parties to verify and ensure compliance under the new rules."       
                                                                           
   The Amateur Service is no longer categorically excluded from certain    
   aspects of the rules, as amended, and licensees can no longer avoid     
   performing an exposure assessment simply because they are transmitting  
   below a given power level.                                              
                                                                           
   "For most amateurs, the major difference is the removal of the          
   categorical exclusion for amateur radio, which means that ham station   
   owners must determine if they either qualify for an exemption or must   
   perform a routine environmental evaluation," said Greg Lapin, N9GL,     
   Chair of the ARRL RF Safety Committee and a member of the FCC           
   Technological visory Council (TAC).                                   
                                                                           
   "Ham stations previously excluded from performing environmental         
   evaluations will have until May 3, 2023, to perform these. After May 3, 
   2021, any new stations or those modified in a way that affects RF       
   exposure must comply before being put into service," Lapin said.        
                                                                           
   The December 2019 RF R&O changes the methods that many radio services   
   use to determine and achieve compliance with FCC limits on human        
   exposure to RF electromagnetic fields. The FCC also modified the        
   process for determining whether a particular device or deployment is    
   exempt from a more thorough analysis by replacing a service-specific    
   list of transmitters, facilities, and operations for which evaluation   
   is required with new streamlined formula-based criteria. The R&O also   
   addressed how to perform evaluations where the exemption does not       
   apply, and how to mitigate exposure.                                    
                                                                           
   Amateur radio licensees will have to determine whether any existing     
   facilities previously excluded under the old rules now qualify for an   
   exemption under the new rules. Most will, but some may not.             
                                                                           
   "For amateurs, the major difference is the removal of the categorical   
   exclusion," Lapin said, "which means that every ham will be required to 
   perform some sort of calculation, either to determine if they qualify   
   for [IMG]an exemption or must perform a full-fledged exposure           
   assessment. For hams who previously performed exposure assessments on   
   their stations, there is nothing more to do."                           
                                                                           
   The ARRL Lab staff is available to help amateurs to make these          
   determinations and, if needed, perform the necessary calculations to    
   ensure their stations comply. ARRL Laboratory Manager Ed Hare, W1RFI,   
   who helped prepare ARRL's RF Exposure and You book, explained it this   
   way. "The FCC did not change any of the underlying rules applicable to  
   amateur station evaluations," he said. "The sections of the book on how 
   to perform routine station evaluations are still valid and usable,      
   especially the many charts of common antennas at different heights."    
   Hare said ARRL Lab staff also would be available to help amateurs       
   understand the rules and evaluate their stations.                       
                                                                           
   RF Exposure and You is available for free download from ARRL. ARRL also 
   has an RF Safety page on its website.                                   
                                                                           
   The ARRL RF Safety Committee is working with the FCC to update the      
   FCC's aids for following human exposure rules -- OET Bulletin 65 and    
   OET Bulletin 65 Supplement B for Radio Amateurs. In addition, ARRL is   
   developing tools that all hams can use to perform exposure assessments. 
                                                                         
   St. Vincent Radio Amateurs on Alert During Volcano Emergency            
                                                                           
   Donald de Riggs, J88CD, on the Caribbean island of St. Vincent, says    
   that on April 13, the 42nd anniversary of the 1979 eruption of the La   
   SoufriŠre volcano, island residents were awakened to another column of  
   volcanic ash creating a thick blanket obscuring part of the eastern sky 
   as the volcano continues to erupt violently.                            
                                                                           
                                      Elna Michael, J88NEK, reported       
                                      strong tremors in Fancy, St.         
                                      Vincent, before being evacuated from 
                                      the Red Zone just ahead of the       
                                      explosive phase.                     
                                                                           
   "Almost all residents in the Red Zone have been evacuated, save for a   
   few diehards who will not move, for reasons unknown," he said.          
                                                                           
   Since the effusive eruption began last December, local hams have been   
   in a state of readiness via 2-meter networks and regional networks via  
   HF. A 24-hour regional HF network and vigil has been active since       
   violent eruptions resumed earlier this month to provide communication   
   support should telephone service be disrupted by the volcanic hazard.   
   This includes a twice-daily link-up on HF with the Caribbean Disaster   
   Emergency Management Agency (CDEMA). There is also a 2-meter gateway    
   via EchoLink on the J88AZ node. The other active VHF repeater is the    
   main resource for domestic communications.                              
                                                                           
   The Grenada repeater, which is linked to St. Lucia and Barbados, is     
   also accessible by hams in Tobago, Trinidad, and St. Vincent and the

   The La SoufriŠre volcano on St. Vincent began its most recent series of 
   explosive eruptions on April 9, sending clouds of hot ash some 20,000   
   feet into the air, blanketing much of the island in ash and causing     
   water and power outages. The volcano is "a constant threat," according  
   to CDEMA. -- Thanks to The Daily DX

   The latest episode of the On the Air podcast (Episode 16) focuses on    
   Parks on The Air (POTA), one of the most popular activities taking      
   place in amateur radio today. We chat with Audrey Hance, KN4TMU, a      
   relatively new ham who recently operated from Panther Creek State Park  
   in Tennessee.                                                           
                                                                           
   The latest edition of Eclectic Tech (episode 30) discusses the          
   continued use of the PSK31 digital mode, and how many amateurs are      
   using it to "rediscover" the joys of real keyboard-to-keyboard          
   conversation. Also, QST and QEX author Phil Salas, AD5X, discusses the  
   revolution taking place in small, inexpensive vector network analyzers,

   A 5-year, $9.3 million National Science Foundation (NSF) grant will     
   allow the University of Alaska Fairbanks (UAF) Geophysical Institute to 
   establish a new research observatory at the High-frequency Active       
   Auroral Research Program (HAARP). A former military facility, HAARP is  
   now operated by UAF and is home to HAARP Amateur Radio Club's KL7ERP.   
   The new Subauroral Geophysical Observatory for Space Physics and Radio  
   Science will be dedicated to exploring Earth's

   upper atmosphere and geospace environment. The facility's 33-acre       
   Ionospheric Research Instrument will be the centerpiece of the          
   observatory.                                                            
                                                                           
   "This NSF support will provide the scientific community increased       
   access to the instruments at the observatory and, hopefully, grow the   
   scientific community," said Geophysical Institute Director Robert       
   McCoy, the project's principal investigator.                            
                                                                           
   A second NSF-funded project will add a Light Detection and Ranging      
   (LiDAR) instrument at the site, which will allow the study of other     
   regions of the upper atmosphere. UAF hopes to add additional            
   instruments over time at the Gakona, Alaska, research site.             
                                                                           
   The research grant will allow scientists to investigate how the sun     
   affects Earth's ionosphere and magnetosphere to produce changes in      
   space weather. Their work will help fill gaps in knowledge about the    
   region, which is important because ionospheric disturbances, if severe  
   enough, can disrupt communication systems and damage the power grid.    
                                                                           
   Research at the observatory is initially expected to include the study  
   of various types of aurora and other occurrences in the ionosphere.     
                                                                           
   The Gakona facility is a prime location for the study of the ionosphere 
   and magnetosphere because of its location in relation to one of Earth's 
   magnetic field lines that reaches deep into the magnetosphere.          
                                                                           
   "Amateur radio will clearly benefit with an improved understanding of   
   ionospheric propagation and space weather physics, and providing        
   improved HF propagation prediction modeling data," HAARP Research       
   Station Chief Engineer and ARRL Life Member Steve Floyd, W4YHD, told    
   ARRL. He said, "Radio science experiments will also provide a valuable  
   data set to encourage development of new radio technologies and         
   modulation methods."                                                    
                                                                           
   Floyd is the trustee for KL7ERP, which, he says, is available "to       
   demonstrate amateur radio to visiting scientists and students, to       
   maintain contact with Alaska hams, and to provide visiting hams with an 
   opportunity to operate from this unique Alaska location." Read an

   2021 at 1 PM EDT (1700 UTC)                                             
                                                                           
   Radio frequency interference (RFI) has been a problem for ham radio     
   operators and shortwave listeners (SWLs) since the radio hobby began.   
   Noise has gotten worse over the last 20 years or so with the advent of  
   widespread solar power, LED lightning, grow lights, and digital         
   devices. Learn all about finding and fixing RFI in today's world.

   The Huntington Library, Art Museum, and Botanical Gardens in San        
   Marino, California, has acquired an archive of papers and               
   correspondence to, from, and about wireless pioneer and Nobel Laureate  
   Guglielmo Marconi. Among the more than 200 pages of correspondence are  
   31 letters from Marconi to his Chief Engineer, Richard Vyvyan, written  
   between 1902 and 1909, regarding the construction and successful        
   implementation of a transatlantic telegraph system. The collection also 
   includes Vyvyan's extensive manuscript overview of wireless technology, 
   "Notes on Long Distance Wireless Telegraphy and the Design and          
   Construction and Working of High Power Wireless Stations," written      
   between 1900 and 1904.                                                  
                                                                           
   "Marconi transformed the speed and effectiveness of telecommunication   
   through wireless telegraphy," said Daniel Lewis, who is responsible for 
   the Huntington Library's history of science and technology holdings     
   from 1800 to the present.                                               
                                                                           
   Marconi was relentless in his attempts to improve on his radio work, as 
   reflected in this archive. "Working very hard to try and find out what  
   are the somewhat occult causes which make signals good one night and    
   unobtainable the next," he wrote to Vyvyan in 1907. "I believe I have   
   found, if not very clearly, the cause of the effects noticed."          
                                                                           
   Vyvyan was largely responsible for the construction and operation of    
   the transmitting station at Poldhu in Cornwall, from where the          
   first-ever transatlantic signal was sent to Newfoundland on December    
   12, 1901. He was also in charge of the Cape Breton Island station the   
   following year, when the first signal was sent in the opposite          
   direction. Read an expanded version.

   Intrepid-DX Group Joins Forces with LA7GIA in Bouvet Island Attempt     
                                                                           
   The Intrepid-DX Group has teamed with DXpeditioner Ken Opskar, LA7GIA,  
   in its quest to activate Bouvet Island, the second-most-wanted DXCC     
   entity according to Club Log. The 3Y0J DXpedition is planned for        
   January through February 2023. A dependency of Norway, Bouvet is a      
   sub-Antarctic island in the South Atlantic. The last Bouvet activation  
   was 3Y0E, during a scientific expedition over the winter of 2007 -      
   2008.                                                                   
                                                                           
   "There's a lot to do, and we have a big financial mountain to climb,"   
   DXpedition co-leader Paul Ewing, N6PSE, said in a recent interview      
   [IMG]with Tim Duffy, K3LR. Ewing will share leadership duties with

   difficult landing, so we're prepared for that."                         
                                                                           
   A 2018 DXpedition to Bouvet was scuttled after severe weather and an    
   engine problem forced the team -- with Bouvet already in view -- to     
   turn back.                                                              
                                                                           
   The plan calls for the 3Y0J team of 14 to board the marine vessel       
   Braveheart in Capetown, South Africa, for "the treacherous voyage to    
   Bouvet," Ewing said. "We will plan to spend 20 days at Bouvet and,      
   weather permitting, we plan to have 14 to 16 good days of radio         
   activity."                                                              
                                                                           
   "This will be an arduous and expensive mission. Our budget is $764,000, 
   and the 3Y0J team will fund much of this mission. We desperately need   
   the global DX community to support our mission and help us make this    
   important activation of the second-most-wanted DXCC entity. It is only  
   through this kind of support that we can achieve our mission of making  
   100,000 contacts or more from Bouvet."                                  
                                                                           
   The Northern California DX Foundation and the International DX          
   Association have already stepped up to the plate.                       
                                                                           
   "We plan to make best use of propagation and modes on 10 - 160 meters," 
   Ewing said in the announcement. Operation will be on SSB, CW, and       
   digital modes. "But I want to make it clear," Ewing told Duffy.         
   "There's no doubt. We are going!"

   Tad Cook, K7RA, Seattle, reports: On April 12, new sunspot group AR2814 
   appeared following 5 days of no sunspots at all. Daily sunspot numbers  
   on the following 3 days were 16, 16 and, 17 taking the average daily    
   sunspot number for the April 8 - 14 reporting week to 7, up from 6.4    
   last week. So far in 2021, 39% of the days had no sunspots.             
                                                                           
   Geomagnetic indicators were quiet, with average daily planetary A index 
   declining slightly from 6.6 to 5.1. Likewise, middle latitude A index   
   changed from 5.6 to 4.1.                                                
                                                                           
   On April 14, Spaceweather.com reported a high-speed stream of solar     
   wind from a hole in the sun's Southern Hemisphere. This could produce a 
   minor geomagnetic storm on April 17.                                    
                                                                           
   At 2338 UTC on April 14, the Australian Space Forecast Centre issued    
   this Geomagnetic Disturbance Warning: "Geomagnetic activity is expected 
   to increase to active levels with a chance of an isolated minor storm   
   period from late April 16, due to coronal hole effects."

   The SSB ARRL Rookie Roundup is Sunday, April 18, 1800 - 2359 UTC. The   
   Rookie Roundup is aimed at hams licensed for 3 years or less. Rookies   
   make as many contacts as possible during this 6-hour event. Rookies     
   work everyone, and non-Rookies work only Rookies. Stations exchange     
   each other's call signs, first names, a two-digit year, and state (US   
   or Mexican), Canadian province, or DX. Rookies can enter as a Single    
   Operator or invite Rookie friends over and operate as Multioperator. Up 
   to five Single Operator Rookies can also enter from their individual    
   stations and submit their total score as a team. This is a great way    
   for clubs to get newer members on the air, and the perfect opportunity  
   to be a mentor to new licensees. Seasoned operators can join in the fun 
   by calling "CQ Rookies." This year, the Rookie Roundup takes place      
   during World Amateur Radio Day. Use the opportunity to wish             
   participants "Happy World Amateur Radio Day" on the air. Logs are due   
   on April 21 (within 72 hours after the event). No late entries will be  
   accepted. Complete rules, logging sheets, and links for submitting your 
   score are on the Rookie Roundup web page.                               
                                                                           
   Researcher and innovator Ulrich Rohde, N1UL, has been awarded the Cross 
   of Merit of the Federal Republic of Germany. He was nominated by Markus 
   Söder, president of the German state of Bavaria and member of the       
   Bavarian Parliament. Söder said that Rohde's work as a scientist,       
   university lecturer, developer, and entrepreneur in the fields of radio 
   frequency and microwave technology "has made a significant contribution 
   to our country's technological advances, prosperity, and security." The 
   Order of Merit of the Federal Republic of Germany, also known as the    
   Federal Cross of Merit, is the highest tribute the Federal Republic of  
   Germany can pay to individuals for services to the nation. Federal      
   President Theodor Heuss established the Order in 1951 on the second     
   anniversary of the founding of the Federal Republic.                    
                                                                           
   Over the Horizon (OTH) radars in ham bands may be too numerous to       
   count. The IARU Region 1 Monitoring System (IARUMS) March newsletter    
   reported that the seemingly ubiquitous Over the Horizon Radars (OTH-Rs) 
   made up about 60% of all interference observations, to the point that   
   "one cannot even count them anymore." The IARUMS presumes that only a   
   few stations are transmitting on often-changing frequencies. In         
   contrast to the past, however, these are more frequently burst systems, 
   which typically transmit for just a few seconds before changing         
   frequency. IARUMS said that only the "Contayner" and "Pluto" systems    
   transmit on a single frequency for longer periods.
