FlexRadio Equips ARRL with FLEX-8000 Series Station for W1AW

There is a new addition to Studio 1 at W1AW, the Hiram Percy Maxim Memorial Station at ARRL Headquarters in Newington, Connecticut: a complete station of the latest gear from , including a FLEX-8600™ Signature Series SDR transceiver, a Maestro C Control Console, Power Genius XL (PGXL) amplifier, and Radiosport RS60CF headset. The equipment is the latest addition to W1AW, which hosts a complement of equipment in each of three operating studios under rotating agreements with major amateur radio manufacturers.

During his visit to present the station to ARRL on Wednesday, July 16, 2025, FlexRadio Chief Technology Officer Stephen Hicks, N5AC, described the station as an addition for the benefit of ARRL members and all visitors to W1AW. ARRL President Rick Roderick, K5UR, and CEO David Minster, NA2AA, were on hand to receive the equipment on behalf of ARRL.

 

“The FLEX-8600 provides all of the latest features that we have,” said Hicks. “And with all the Flex radios, they are continuously upgradable, so we have software releases on an ongoing basis and add features and functionality to it. … ARRL members and W1AW visitors can come in here and try this equipment out and get used to it.”

ARRL Director of Marketing and Innovation Bob Inderbitzen, NQ1R, expressed gratitude for the collaboration with FlexRadio, saying “We’re grateful to have W1AW equipped with a full FlexRadio station, allowing members and visitors to operate and enjoy this current-generation technology when they come to experience the latest in amateur radio innovation.” Inderbitzen explained that ARRL’s partnership with FlexRadio and its ongoing arrangement with manufacturers highlights a shared commitment with the industry to advance amateur radio by offering a hands-on experience to W1AW visitors.

 

Hicks and his FlexRadio colleague, Tony Brock-Fisher, K1KP, also provided a highly informative presentation to ARRL staff on the forthcoming ™ series of 500-watt SDR transceivers. Their talk highlighted the radio’s innovative use of polar modulation to address intermodulation distortion — a common challenge in linear amplification methods — while also reducing power consumption and heat generation. The technology has made it possible to reduce the weight and footprint of a high-power HF station into a lightweight radio that can easily travel as an airline carry-on.

 

Take Part in HamSCI’s Meteor Scatter QSO Party

The Ham Radio Science Citizen Investigation (HamSCI) is preparing for a series of upcoming meteor scatter (MS) experiments. Operating will take place during two well-known meteor showers: Perseids, August 11 - 12, 0000 to 2400 UTC, and Geminids, on December 12 – 13.

 

 

This is a combination “special event and contest” to generate contact data during meteor scatter events using the 6- and 10-meter bands. Ten meters has been used infrequently for meteor scatter study due to past symbol rate limits. However, with recent changes in Federal Communications Commission rules, WSJT-X/MSK144 protocols may now be used on HF bands.

 

Data will be collected from both bands during the scheduled times in August and December, and will be analyzed offline, using both PSK Reporter raw data and operator contact logs from WSJT-X. User data, including both logged contact and received reports, are necessary for valid experimental analysis. The latter can be provided by any receive system reporting on MSK144 through PSK Reporter.

 

Operators are needed now to be active (i.e., CQ-) on MSK144; or passive, if possible, reporting via PSK Reporter as “monitors.” The best times are early morning hours prior to 10 meters opening to F2 propagation. Meteor scatter propagation occurs well below F2 and is supported in or near the E layer where the meteor ionization tracks occur.

 

Saturday mornings are being used regularly to announce and coordinate 10-meter contacts using . Announcements are also made on the Front Range Six Meter due to the substantial number of meteor scatter operators in that group.

 

To be successful, both active and passive operators are needed. The upcoming August meteor shower is an excellent time to set up your equipment and join with other operators preparing for the events. At a later date, the HamSCI team will be collecting operator contact information.

 

Contest rules can be found at and a description of the HamSCI Meteor Shower QSO Party - 2025 at .

Safety Stand-Down: Look Up and Live

By Sierra Harrop, W5DX

ARRL Public Relations and Outreach Manager

Electricity is a killer. About 150 people die each year at work from contact with electricity, according to the Electrical Safety Foundation International. Half of those are from contact with power lines. That data is just workplace deaths, so recreational and public service volunteering aren’t even accounted for.

 

In a recent article, ARRL New Mexico Section Manager Bill Mader, K8TE, at ARRL Field Day sites. I’d like to share a simple phrase that may enhance your situational awareness: Look up and live.

 

“Look up and live” was drilled into me and every other television news employee who worked with electronic news gathering vehicles that had a pneumatic mast or satellite dish. It was the title of .

 

In TV news, where I spent the first two decades of my professional career, there was always a deadline and often a tremendous sense of urgency at the scene of breaking news to get a live shot up first. Before the days of bonded cellular internet streaming, we used radio – microwave and satellite – to take viewers to the scene.

 

No matter the pressure from news managers, safety was paramount. When we approached a scene, we made sure to park the live truck at least 10 feet away from overhead wires to comply with regulations. My personal minimum was two truck-lengths from any lines, ideally a whole mast-length. If I had a 58-foot mast, I’d try to park at least 58 feet away from the nearest power line.

 

Identifying overhead lines was ritualistic: As I arrived, I got out of the vehicle, walked 20 feet away, looked up and walked around the entire perimeter of the truck while deliberately searching for overhead lines and obstructions. This additional 45-second process could feel like an eternity when news was unfolding dramatically for me to capture and report – but I couldn’t go live if I was dead.

 

In pursuit of our amateur radio hobby, we should apply even more diligence. There’s no pressure to get on for a ham radio activation. Take your time, walk around, be diligent. Look up and live.

 

Portable masts, vertical antennas, wire antennas slung up into a tree – anything you put up can become energized if it contacts an overhead wire. Do not take chances. Even what appears to be a phone or fiber line could be carrying lethal voltages. Do not become the path to ground.

 

One additional tip that I hope never applies to a radio amateur: Should a vehicle you’re in become energized by a fallen line or a mast erected into power lines, do not leave it unless it is on fire. Call for help via phone or ham radio. Yell at any bystanders to not approach your vehicle. Electricity spreads out from a path to ground in concentric rings of decreasing voltage. Being in contact with different voltages is what will kill you. If a fire requires you to exit, carefully jump clear of the vehicle so as to not contact the vehicle and ground simultaneously. Be mindful of your movements: “Bunny hop” with your feet together or shuffle your feet on the ground in small increments without lifting either of them. Do not provide a path between the different potentials by walking normally or by falling and catching yourself with your hands.

 

Please be careful when erecting portable gear within the wires environment. Remember: Look up and live.

The ARRL Solar Report

ARRL Solar Report for July 17, 2025

Solar activity has been at low levels this past week. The largest flare of the period was July 16 from Region 4143.

 

Continued influence from the coronal hole (CH) high speed stream (HSS) will maintain higher-than-normal electron flux at geostationary orbit through July 18. The greater than 2 MeV flux will be moderate to high, especially during the diurnal maxima (pressure oscillation) during this time.

 

Solar wind parameters continued to be enhanced under positive polarity CH HSS influence. This is expected to continue through July 19.

 

The 10.7-centimeter flux: July 17, 125; July 18, 128; July 19, 122; July 20, 118; July 21,120; July 22, 125; July 23, 125; July 24, 128. No radio blackouts were observed over the past 24 hours.

 

Predicted Sunspot Numbers: July 17, 135; July 18, 136; July 19, 134; July 20, 120; July 21, 154; July 22, 137; July 23, 140.
