What do the Dayton Hamvention® flea market and Xenia, Ohio, weather have in common? They each offer a little bit of everything! Friday’s hot and humid afternoon was followed by thunderstorms at night and cool, windy, weather on Saturday. The Hamvention itself, though, provided consistently positive experiences for just about everyone. ARRL activities were highlighted by th...

After weeks of calm, solar activity is suddenly high again, with two
strong solar flares erupting from opposite sides of the Sun. A
Coronal Mass Ejection (CME) was associated with a strong solar flare
on May 12, but modeling shows the ejection passing behind Earth. The
geomagnetic field has been at unsettled to active conditions.

A CME associated with a filament eruption in the northern hemisphere
is...

It was a flurry of activity around the exhibit space for ARRL The National Association for Amateur Radio® and beyond. Trucks being unloaded, tables being arranged, boxes being opened and even tablecloths being ironed were among the sights and sounds Thursday at Ohio’s Greene County Fairgrounds as hundreds of ham radio manufacturers, retailers, clubs, and organizations prepared for Friday’s open...

ARRL The National Association for Amateur Radio® in a recent filing encouraged the Federal Communications Commission (FCC) to listen to industry stakeholders about the detrimental impacts that changes to the 902-928 MHz band would have for current users.

The FCC is considering a petition by NextNav, Inc., a licensee in the 900-MHz Location and Monitoring Service (LMS), to reconfigure the 902-928...

The Solar Geophysical Activity Report and Forecast from the
USAF/NOAA indicates that solar activity has been at low levels for
the past 24 hours.

There are currently four numbered sunspot regions on the solar disk.
Solar activity is expected to be low with a chance for M-class
flares on May 10 and 11.

A simultaneous filament eruption produced a narrow Coronal Mass
Ejection (CME) signature that was fir...

A session of the ARRL Teachers Institute on Wireless Technology (TI) is being hosted this summer by the Johns Hopkins University Applied Physics Lab in Laurel, Maryland. This marks the first time a major research university has hosted the ARRL program.

The TI program is expanding significantly in 2025. Already, an institute was held on Staten Island, New York, to mark the first regional session....

The Heritage CQ Amateur Radio Hall of Fame, created by longtime amateur radio publisher Richard Ross, K2MGA (SK), will continue to honor amateur radio operators on a new section of the Hamgallery.com website.

CQ magazine ceased publication in October 2023. Ross died on April 27, 2024, and the change was made with the permission of his widow, Cathy.

The Heritage CQ Amateur Radio Hall of Fame hono...

On May 2, Spaceweather.com reported: "Astronomers are monitoring a
very large sunspot now turning toward Earth. Sunspot AR4079
stretches more than 140,000 km from end to end and has two dark
cores each large enough to swallow Earth. Moreover, it is surrounded
by a ring of Ellerman Bombs.

"Ellerman bombs are a sign of magnetic complexity in a sunspot.
Opposite polarities bump together, reconnect, and-...

Eric Tichansky, NO3M, of Saegertown, Pennsylvania, has been issued the first Worked All States award from ARRL The National Association for Amateur Radio® for the 630-meter band. He picked up the award at ARRL Headquarters in Newington, Connecticut, on April 21, 2025. That was the culmination of years of study, work, and experimentation.

Tichansky had a draw to 160 meters e...

Solar activity has been at low levels with only minor C-class
flaring through April 24, 2025, and is expected to be moderate with
a chance of M-class flares (R1-R2, Minor-Moderate) through April 26.
No Earth-directed Coronal Mass Ejections (CMEs) have been observed.
A southwest CME was observed on April 23 and is considered to be
far-side due to the lack of any on-disk plasma motion/flare
activity.
