Active sunspot returns

(Source: Spaceweather via Troy Riedel)

This weekend, old sunspot AR2738 is returning from a two-week trip around the farside of the sun. After re-appearing late yesterday, the sunspot quickly produced two CMEs (coronal mass ejections), signalling that it may be even more active than before. Last month when it crossed the face of the sun, AR2738 crackled with low-level flares and strafed Earth with loud shortwave radio bursts.[…]

What are Shortwave and HF broadcast seasons?

After posting recent shortwave broadcast schedules and updates for the A19 season, SWLing Post reader Tom Cook asked, What is A19?”

Excellent question, Tom! And, frankly, one I’ve never answered here on the SWLing Post even though it’s so fundamental to understand HF broadcast scheduling.

Shortwave broadcast schedules are coordinated for two seasons:

  • a summer season which starts on the last Sunday in March and ends on the last Sunday in October; and
  • a winter season which starts on the last Sunday in October and ends on the last Sunday in March.

The summer season is often referred to as the “A” season, and winter the “B” season. This is often abbreviated, so “A19” equates to the 2019 “A” or summer season.

For newcomers to shortwave listening, the confusing bit is that three month period between January and March in any given year–the end of the “B” season which started the previous year. For example, in February 2019 you would still be in the B18 broadcast season even though you’re already in the year 2019.

At time of posting (May 4, 2019), we are in the A19 HF broadcasting season.

Thanks for asking your question, Tom! I hope this explanation helps.

“The dream of Biafra lives on in underground Nigerian radio broadcasts”

Many thanks to SWLing Post contributor, Ed, who shares the following story about Radio Biafra from the LA Times:

Every evening as 5 o’clock approaches, the clogged, perpetually dusty streets of this industrial city in southeastern Nigeria begin to empty.

Groups of men just off work go inside, shut their doors and tune their radios to 102.1 FM.

Then an anthem begins to play, and a voice says “Kedu” ­ “how are you” in the Igbo language ­ to welcome listeners to the daily broadcast of Radio Biafra.

For the next 90 minutes, hosts and various guests proselytize for the revival of an old dream: the creation of an independent state called Biafra.

The broadcasts, conducted live from an undisclosed location in Nigeria, are illegal, and the group behind them ­ the Indigenous People of Biafra, or IPOB ­ has been classified by the government as a terrorist organization since 2017. Its leaders say they eschew violence and want a peaceful settlement of the issue through a national referendum.

Activists say people caught listening to the station have been arrested or beaten. But many residents here say they are willing to take the risk.

Radio Biafra is a daily reminder of the bloody civil war that ravaged Nigeria between 1967 and 1970. The conflict started when a Nigerian military general, Chukwuemeka Odumegwu Ojukwu, declared an independent state of Biafra. It ended after more than a million deaths, mostly from starvation after the government imposed a food blockade on the region.

Ultimately, the rebels surrendered and the area was reintegrated into Nigeria under the government motto “No victor, no vanquished.”

But the memory of the brutal war looms large in Aba, feeding enthusiasm for the broadcasts despite extremely long odds that Biafra will ever come to be.[…]
