World Amateur Radio Day on April 18 Celebrates 95th Anniversary of the IARU
Saturday, April 18, is World Amateur Radio Day (WARD), this year marking the 95th anniversary of the International Amateur Radio Union (IARU). Around the world, amateur radio special event stations — most sponsored by IARU member-societies — will mark the event on the air, starting on April 18 at 0000 UTC and continuing until April 19 at 0000, honing skills and capabilities while enjoying global friendship with other amateurs worldwide. The theme for WARD is “Celebrating
“A few short weeks ago, many of us could not imagine the levels of isolation that we are now dealing with and the sacrifices of many on the front lines of the pandemic,” Ellam said. “As we have done in past challenges to our society, amateur radio will play a key part in keeping people connected and assisting those who need support.”
Ellam said he’s coming off his own 14-day isolation after returning from overseas. “I am touched by the kindness of strangers who assisted me when I was unable to leave my house,” he said. “It strikes me amateur radio operators, who give so much during these times of crisis are not limited to assisting over the air. Amateurs are true volunteers, and I would encourage everyone to assist in the community as they are able to.”
On April 18, 1925, the IARU was formed in Paris, with ARRL cofounder Hiram Percy Maxim, 1AW, in attendance. Radio amateurs were the first to discover that shortwave spectrum could support worldwide propagation, and in the rush to use these shorter wavelengths, amateur radio found itself “in grave danger of being pushed aside,” as IARU history puts it. Two years later, at the International Radiotelegraph Conference, amateur radio gained allocations still recognized today – 160, 80, 40, 20, and 10 meters. From an initial 25 countries, the IARU has grown to include 160 member-societies in three regions.
How to Participate
World Amateur Radio Day is not a contest but an opportunity to talk about the value of amateur radio to the public and our fellow amateurs. It is also a great opportunity to talk about your club and amateur radio in local media.
In this time of social isolation, amateur radio continues to remain relevant in bringing people together through radio while providing essential communication in the service of communities.
COVID-19 Guidelines Could Affect Some IARU HF World Championship Participation
The IARU HF World Championship is just over 2 months away — July 11 – 12. The International Amateur Radio Union (IARU) says that it’s essential to take the global COVID-19 pandemic into account when planning participation, including by IARU member-society Headquarters (HQ) station teams. Multioperator and IARU member-society HQ station operations must adhere strictly to the regulations and physical-distancing guidelines issued by the responsible health authorities and the World Health Organization in effect at the time
“This may reduce participation, but it is vital that the IARU, its member-societies, and individual radio amateurs behave as responsible members of the global community,” the IARU said. “Radio amateurs should always look for opportunities to address communications challenges through the application of technology.”
The IARU points out that a growing number of stations, including multioperator stations, can be operated remotely, and it encourages their participation in the HF World Championship wherever national regulations permit.
The objective of the IARU HF World Championship is “to support amateur self-training in radiocommunications including improving amateur operating skills, conducting technical investigations, and intercommunicating with other amateurs around the world, especially IARU member-society headquarters stations.” The event takes place on 160, 80, 40, 20, 15, and 10 meters.
The special rules governing IARU member-society HQ stations allow multiple sites to be used, again subject to national regulations. HQ stations will still be able to participate, but possibly not at their usual level.
Hamvention QSO Party Set for Saturday, May 16
The Hamvention QSO Party, a sort of virtual Dayton Hamvention®, will take place on the HF bands on May 16, which would be the Saturday of the now-canceled event.
“Let’s celebrate the many years we have all had at the Great Gathering we call Hamvention,” said an announcement over the signatures of Tim Duffy, K3LR, and Michael Kalter, W8CI. “We also want to
The Hamvention QSO Party will be a 12-hour event, from 1200 UTC until 2400 UTC on May 16. Operate CW or SSB on 160, 80, 40, 20, 15, and 10 meters, exchanging signal reports and the first year you attended Hamvention. If you have never attended Hamvention, send “2020.”
Designated members of Hamvention’s host, the Dayton Amateur Radio Association (DARA), will activate DARA’s W8BI. Participants can add 10 points for each band/mode contact with W8BI (12 available).
Post scores (number of contacts) to 3830scores.com within 5 days of the event. An online certificate will be available to print. No logs will be collected.
N1MM Logger+ has provided a user-defined contest module for the event. More information is on the N1MM Logger+ website.

New TQSL Version 2.5.2 Provides Better LoTW Rover Support, Other Improvements
The latest version of TrustedQSL (TQSL), version 2.5.2, offers improved Logbook of The World (LoTW) support for operations from several locations, as well as the ability to detect uploads that contain incorrect location data. The primary new feature in TQSL 2.5.2 allows logging programs, in conjunction with TQSL, to avoid incorrect contact uploads, while adding mechanisms to allow easy uploading of logs for roving stations. LoTW had required rovers to identify each location
When a log is signed by TQSL, the station details — call sign, DXCC entity, grid square, and other location details provided by the selected station location (and call sign certificate) — are compared with the details in the log. If the US state and station location in a log do not agree, TQSL 2.5.2 will reject the contact, detecting errors in instances when an incorrect station location has been chosen. This feature will necessitate changes in many logging programs, because it requires that the log provide station details previously not used by TQSL. Once a logging program supplies these (MY_STATE, MY_DXCC, MY_CQ_ZONE, etc.), then TQSL will validate them against the log. Currently, Cabrillo logs use the CALLSIGN field to verify that the contacts are for the correct call sign.
Optionally, a station performing roaming operations (e.g., from multiple grid squares) can choose to have TQSL assume that the log is correct. When call sign or home station are provided with the log, TQSL will automatically update the details on the upload. Select “Override Station Location with QTH Details from your Log” on the “Log Handling” preference page to enable this feature.
Circuit Board for Bare-Bones Ventilator Moves Toward Production with Radio Amateurs’ Help
Radio amateurs continue to play key roles in developing the electronic control system for an open-source/architecture, modular, low-cost human patient ventilator. The device itself was designed by researcher Sem Lampotang and his team at University of Florida Health — the school’s academic health center — using such commonly available components as PVC pipe and lawn-sprinkler valves. The idea is to
“The way I looked at it is, if you’re going to run out of ventilators, then we’re not even trying to reproduce the sophisticated ventilators out there,” Lampotang said. “If we run out, you have to decide who gets one and who doesn’t. How do you decide that? The power of our approach is that every well-intentioned volunteer who has access to Home Depot, Ace, Lowe’s, or their equivalent worldwide can build one.”
His team is working on adding safety features to meet regulatory guidelines, then they will run engineering tests to determine safety, accuracy, and endurance of the machine, which can be built for as little as $125 to $250.
Dr. Gordon Gibby, KX4Z — a retired associate professor of anesthesiology at the University of Florida and an electrical engineer — is among those involved in the project, developing control-system prototypes. He reports that a trial printed circuit board is being created, populated, and tested prior to large-scale fabrication. “This should lead to a documented open-source design that can be replicated or
improved upon by any interested manufacturer,” Gibby said, noting that the board could be built anywhere in the world, based on the Arduino Nano microcontroller.
“A huge amount of work has gone on in the design of the circuit boards,” Gibby told ARRL. “We have at least two, maybe three designs, ready for fabrication.” Current design specifications and a video of prototypes have been posted online. The Arduino-based control software will set the respiratory rate and other key parameters in treating critically ill coronavirus victims. Other radio amateurs involved in the control system aspect of the project include Jack Purdum, W8TEE, and uBITX transceiver maker Ashhar Farhan, VU2ESE.
Using a Groups.io forum, up to 140 volunteers have been studying or working to push the project to completion. Software is being created by multiple volunteers, with amateur radio operators involved in that phase as well.
The ventilator’s valves will precisely time the flow of compressed oxygen into a patient with lungs weakened by viral pneumonia in order to extend life and allow time for the body to clear the infection. Read more.
The K7RA Solar Update
Tad Cook, K7RA, Seattle, reports: After 5 days of new Solar Cycle 25 sunspot activity, sunspots vanished. The average daily sunspot number rose from 3.6 last week to 5.1 this time. The average daily sunspot number over the days sunspots were visible — March 31 – April 4 — was 12.2, but these observations straddle two reporting weeks.
Predicted solar flux for the next 45 days is 70 on April 9 – 13; 68 on April 14 – 23; 70 on April 24 – May 7; 68 on May 8 – 20, and 70 on May 21 – 23.
Predicted planetary A index is 5, 8, and 8 on April 9 – 11; 5 on April 12 – 14; 10 on April 15; 8 on April 16 – 19; 5 on April 20 – 25; 10 on April 26 – 27; 5 on April 28 – May 6; 8 on May 7-8; 5 on May 9 – 11; 10 on May 12; 8 on May 13 – 16; 5 on May 17 – 22, and 10 on May 23.
Sunspot numbers for April 2 – 8 were 12, 13, 11, 0, 0, 0, and 0, with a mean of 5.1. The 10.7-centimeter flux was 69.8, 69.9, 70.1, 71.2, 69.9, 69.9, and 70.4, with a mean of 70.2. Estimated planetary A indices were 7, 9, 5, 5, 3, 4, and 13, with a mean of 6.6. Middle latitude A index was 7, 7, 4, 4, 2, 3, and 10, with a mean of 5.3.
A comprehensive K7RA Solar Update is posted Fridays on the ARRL website. For more information concerning radio propagation, visit the ARRL Technical Information Service, read “What the Numbers Mean…,” and check out K9LA’s Propagation Page.

Several Countries Authorize COVID-19 Advisory Suffixes
A growing number of countries have authorized selected radio amateurs or organizations to identify with suffixes that propagate the advice to stay at home during the COVID-19 pandemic. A60STAYHOME/# call signs are on the air from the United Arab Emirates, while the Kuwait Amateur Radio Society’s 9K9STAYHOME; TC1STAYHOME, in Turkey, and the Saudi Amateur Radio Society’s HZ1STAYHOME are among these stations spreading the word from that part of the world.
In Canada, Michael Shamash, VE2MXU, is using VC2STAYHOM “to raise awareness for social distancing during the COVID-19 pandemic.” Canada limits call sign suffixes to seven characters. On the air from Indonesia is 8A1HOME; Indonesia limits suffixes to four characters.
SRAL, Finland’s IARU member-society, is sponsoring the Global Amateur Radio Network special event, with “messenger stations” on the air with STAYHOME suffixes, such as OH5STAYHOME. The event runs through July 8. The Global Messenger Award and the Stay Home Award are available, with credit for working “STAY HOME” stations in other countries and at least five of the Finnish stations.
Also in Finland, the Amateur Radio Club of Lahti, OH3AC, has been authorized to use OH0PYSYKOTONA and nine others in that series with a different number in the prefix. “Pysy kotona” is Finnish for “stay home.” Contacts will be confirmed via LoTW with paper cards via OH3AC. An award is available for working all 10 in the series.
CR2STAYHOME will be on the air from Sao Miguel, one of the nine islands in the Azores, while operators in Bosnia and Herzegovina will transmit the alert as E7STAYHOME (QSL via E77E and E73Y or LoTW). R3STAYHOME is another special call sign (QSL via the bureau to R3KEE). Also, listen for 5B4STAYHOME from Cyprus, operated by Norman Banks, 5B4AIE (no QSLs).
Finland’s SRAL has suggested the new Q signal QSH for “stay happy and healthy,” while N3ADF is encouraging the use of QWH for “wash hands.”
FCC Part 97 Amateur Radio Service rules do not provide for amateur call sign suffixes longer than three characters, but a potential workaround exists. As §97.119(c) of the FCC’s Amateur Radio Service rules states: “One or more indicators may be included with the call sign. Each indicator must be separated from the call sign by the slant mark (/) or by any suitable word that denotes the slant mark. If an indicator is self-assigned, it must be included before, after, or both before and after, the call sign. No self-assigned indicator may conflict with any other indicator specified by the FCC Rules or with any prefix assigned to another country.”
