All month long, during January 2015, a group of volunteers using the special event callsign, “K3Y” with a slant-region number (i.e., “K3Y/3” or “K3Y/0”), were on the amateur radio HF bands (and some, on six meters).  I was one of these volunteers, operating nearly every day of the month for at least one hour, but some times a few hours per day.

“K3Y,” the Straight Key Century Club’s annual January celebration, commemorates the club’s founding in 2006 following the American Radio Relay League’s Straight Key Night. A small group of participants wanted to extend the fun of SKN throughout the year. The SKCC is the result.

For the first three years, the club’s founders used K1Y, K2A, and K3Y as the celebration’s special-event calls. But someone cleverly noticed that a 3 is nothing more than a backwards, curvaceous E. This “KEY” event has operated under the K3Y call ever since.

The on-air party is open to members and non-members alike. It runs from 0000 UTC Jan. 2 through 2359 UTC Jan. 31. It’s a great time to introduce others to the joys of hand-crafted Morse code using straight keys, bugs, and side swipers.

In this video, you can see this operation at my ham radio shack, as I am the control operator of the special event station, “K3Y/0”, during one of the many shifts. “K3Y” is the special event callsign of the Straight Key Century Club (SKCC). The special event operates each January.

In the following video, you can see some of the QSL cards associated with this year’s operation, and then some other QSL cards in my collection.

How about that: It's the first episode of Linux in the Ham Shack for 2015! We hope everyone is having a great new year so far. In this episode, we talk with David Rowe, VK5DGR, of Adelaide, South Australia. David is an audio engineer, Ph.D. scholar, inventor of Codec2 and co-author of FreeDV, among his many accolades. We talk to David about his projects, Linux, amateur radio, life in Australia, LinuxConf AU, the new SM1000 FreeDV device, the amount of energy it takes to make a Krispy Kreme donut, home built electric cars, and much more. Until next time...

Special event, “K3Y,” the Straight Key Century Club’s annual January celebration, commemorates the Straight Key Century Club’s founding in 2006 following the American Radio Relay League’s “Straight Key Night” (SKN). A small group of participants wanted to extend the fun of SKN throughout the year. The Straight Key Century Club (SKCC) is the result.

For the first three years, the club’s founders used the special event callsigns of K1Y, K2A, and K3Y as the celebration’s special-event calls. But, someone cleverly noticed that a ‘3’ is nothing more than a backwards, curvaceous ‘E’. This “KEY” event has operated under the special event callsign of ‘K3Y’, ever since.

The on-air party is open to members and non-members alike. It runs from 0000 UTC Jan. 2 through 2359 UTC Jan. 31. It’s a great time to introduce others to the joys of hand-crafted Morse code using straight keys, bugs, and side swipers.

Being involved in VLF amateur radio is a very specialised activity requiring special (but low cost) kit to be successful. Casual listening is highly unlikely to be successful. Long distance reception of amateur VLF signals usually involves looking for signals using Spectrum Laboratory software locked to a VLF MSK signal so that very narrow bandwidths can be looked at for hours or days on end.

Most amateur VLF tests are done on 8.27kHz as this is unallocated spectrum in many countries.

News about amateur VLF activity can be found at https://sites.google.com/site/sub9khz/ . There has been very little amateur VLF work done this year but amateur VLF signals have crossed the Atlantic.

Tests using utilities assisted earth-mode do not involve big loading coils. Just under 6km has been achieved with just 5W using this mode, before I had my stroke! The kit was simple too. See https://sites.google.com/site/sub9khz/earthmode .

One of the things I am really looking forward to, when fit again, is some more field work with VLF using earth-mode.

Look at this huge sunspot, the largest yet of Sunspot Cycle 24! It is about the same diameter as Jupiter! Notice how tiny Earth is, in comparison. Sunspots are regions on the Sun’s photosphere, formed by the “convection” of solar plasma deep inside the Sun, causing the twisting and shifting of magnetic fields. They look like spots on the photosphere because they are cooler than their surrounding solar material, giving them their dark, blemish-like appearance.

The sunspot is the largest since November 1990, and is larger than a monster sunspot that spawned a series of major solar flares over Halloween in 2003. AR 2192 was one of the biggest observed sunspots of all time, ranking 33rd largest of 32,908 active regions since 1874, according to NASA scientists C. Alex Young and Dean Pesnell.

Interestingly, this sunspot never released any major coronal mass ejection (CME), because the magnetic fields were too strong to let any significant plasma escape! However, this sunspot group unleashed a fair number of moderate to strong x-ray flares (see one of them in this video at < http://g.nw7us.us/1s7L0vF >). All told, AR 2192 popped off 26 M-class flares, and six X-class flares! Of course, during the last sunspot cycle, Cycle 23, there were many active sunspot regions unleashing flare after flare within hours of each other. That’s typical during the active phase of most sunspot cycles. This cycle, however, is one of the weakest on record, so this large sunspot with its many flares is exciting.

A Close-up of AR 2192

Each sunspot region gets a consecutive number assigned to it by the National Oceanic and Atmospheric Administration (NOAA). This sunspot region is NOAA AR (active region) Nr. 12192 (we often drop the first digit when speaking of a sunspot, so in this case, this region was often referred to as AR 2192).

One of the many x-ray flares originating from Active sunspot Region AR 2192 – this one seen in Extreme Ultraviolet at 131 Angstroms.

This sunspot region increased the ionization of the ionosphere, creating excellent conditions on all of the high frequency spectrum (shortwave, or HF). Even ten meters was alive with world-wide propagation. And, the best news is that this provided an exciting playing field for the CQ WW SSB contest in late October, 2014.

This sunspot region has now rotated away, but may return on about 24 days.
