Why would an amateur radio operator be interested in space weather?  Is it worth the time and resources to forecast propagation, in the daily operation of a typical ham radio station?

Gary, host of the popular ‘Ham Radio Now’ video podcast, talks with Tomas Hood (NW7US), propagation and space weather columnist for CQ Amateur Radio Magazine (and in the late ‘Popular Communications Magazine’ as well as ‘CQ VHF Quarterly Magazine’) and The Spectrum Monitor Magazine. Gary discusses with Tomas how scientists forecast space weather, and how the average ham radio operator can also make predictions, and what propagation forecasting can bring to the daily operations of an amateur radio enthusiast.

Tomas, NW7US, talks about radio propagation on shortwave (HF) as well as space weather.

As the propagation columnist for several amateur radio magazines, I hear from a diverse group of interested people that find space weather and the propagation of radio waves fascinating. I admit: I am a space weather and radio propagation nut, and it is always good to correspond or meet with other interested folks. This is an aspect of our hobby that never grows old, as there is so much that we don’t yet know–we communicators are in a perfect space to make discovery and to make improvements to our understanding of this science.  Over the years, I’ve heard a lot from readers of my columns, expressing their fascination with the science of radio and solar phenomenon.

Are you interested in learning about the Sun and the Sun-Earth connection (space weather), including topics of sunspots, solar flares, coronal mass ejections, and so on?  Do you want to delve deeper into topics including the ionosphere, the magnetosphere, and how radio waves propagate from transmitter to receiver?

You might consider a time-proven “course”–material that is very comprehensive–that you can self-study, to become well-versed in this information. The course (one that has been used in professional disciplines) is offered either stand-alone, or bundled with the ray-tracing PropLab PRO software. 

Some may say, “But, I like the magic of just getting on the air and trying my luck! If I learn all this stuff, then it becomes science, and not a hobby.” It is true that there’s a joy at being dazzled with the magic of radio; buy a super cool transceiver, and a factory-made antenna with coax already fitted with connectors, adding the necessary accessories to make it come alive, then begin exploring the shortwave frequencies. Magical, indeed! But, there are many in the hobby that wish to learn how all of that works. Some even begin learning how to build antennas, radio kits, and discover the joy of the “science” of radio. A few eventually take the step with gained “scientific” knowledge of electronics, and they design and build equipment for their hobby. The course is part of that mix: learning how the Sun affects getting a radio signal from point A to point B, and how to leverage their time and efforts, is a joy, indeed.

If any disclosure is necessary, here you go: The proceeds from a purchase of this course go to the funds I use to keep cw.HFRadio.org, swl.HFRadio.org, and other resources at HFRadio.org, plus http://SunSpotWatch.com up and running. There are monthly fees, yearly fees, and software licensing to cover, as well as the purchase of hardware from time to time. These operating and maintenance funds are mostly covered by me, Tomas, NW7US, out of my personal funds. Any donations and sales helps out.

Colorado’s first week to host the W1AW/Ø portable station in celebration of the ARRL Centennial events has come and gone.  This particular week was a busy week for me both at work and in the hobby of amateur radio.  In addition to working two shifts operating W1AW/Ø, I also presented the Summits on the Air program presentation to two area amateur radio clubs.  Yes…I also managed to keep my streak of at least one QSO a day alive.

As Colorado began hosting the W1AW/Ø portable operations, we also fell right into the middle of a weather pattern which almost like clockwork the heavy storms would roll into the Denver area from the west.  These storms produced all your typical spring storm weather scenarios including rain (lots of rain in some areas), hail (enough to bring out the snow plows), thunder bolts and lightning (all very, very frightening) and yes…tornados.   Tornados are somewhat rare in the metro Denver area, but this particular week we had sightings just about every day.

My first shift to operate W1AW/Ø was scheduled to begin at 0000z on Friday, (Thursday evening local).  The storms rolled through Denver right on cue with tornado sirens and flashing of lightning around the area.  Below radar image captured about two hours before my shift would start.

Thankfully the clouds parted just before the start of my shift.

On time, I began calling CQ on 20m.  There had been a short gap between operators and our fellow hams were ready to attempt to work Colorado.  Quickly I built a small pileup and began operating the strongest stations I could hear.  I’m really glad I spent many evenings operating just as my own callsign and sharpening my skills in working small pileups.

If you’ve been listening to the HF bands in the past week or two, you certainly know conditions have been poor with noise levels very high on the bands.  Of course the storms which had moved through Colorado certainly were not helping with overall conditions.

My friend Martin, W3MLK was my first contact and he was kind enough to run a few minutes of video/audio and posted on YouTube.  Martin’s QTH is in Delaware.   Thank you Martin for recording my audio.

Watch this video on YouTube.

Statistically speaking, my Thursday shift was far easier and a lot more enjoyable as band conditions were stronger.  I managed 348 QSO’s during my three hour shift compared to only 156 on Sunday morning (1500 – 1800z).  While I’m not sure how this compares with other operators, I enjoyed my time operating W1AW/Ø and representing the Centennial State of Colorado in the ARRL Centennial Event.  It was a lot of fun!

OK….it’s now time to get back to work.  My lunch break is over and this is another busy week in the office.

Until next time…

Happy 100th Birthday, ARRL! You don’t look a day over 50!

I wonder if there will be another special stamp issued this year?

In this episode of Linux in the Ham Shack, Pete goes AWOL. While he’s out being dishonorably discharged, Harrison and Cheryl step in to fill his medium-sized shoes. We also get an interview with Bob, W9YA, current maintainer of YFKTest. He tells us all about the new and exciting world of YFKTest and how it’s not, in fact, dead.

I truly had a blast this past weekend working 20m SSB contacts and giving away 5 points as a VE during the year long ARRL Centennial QSO Party.  As I mentioned in an earlier blog posting, I will be representing the Centennial State of Colorado when the W1AW/Ø portable operations schedule makes a stop in Colorado.  W1AW/Ø will be on the air from Colorado 21-27 May.  My contest operating is typically limited to Field Day and the Colorado QSO Party, so I wanted to spend some time on the air over the next few weeks brushing up on my “operating a pile-up” skills. 

I spent about 3 hours “on the air” over the Easter weekend and managed to add about 180 SSB contacts to  my log.  If you’ve done any operating the past few days you are well aware that band conditions have been up and down.  I was surprised at the feedback I received regarding my audio quality.  I think fellow hams are surprised to know that I’m running just 100w into a hamstick dipole mounted just above my roofline.  But this is the way for those of us living in HOA-hell.

Of course, I also have some weird issue going on with my Yaesu FT-950.  I promise I didn’t let the magic smoke out, but something is seriously wrong with my SSB workhorse.  You can read more about some of the testing I’ve done here.  As I stated in that blog posting, I do plan to try another power supply.  I’ll be pleasantly surprised if the issue is with my current power supply.  But I’m also prepared to quickly send my 950 to Yaesu California.  I need to get it back in time for when I operate W1AW/Ø.

If I had the privilege to work you over the past weekend, thank you for answering my CQ and I most certainly look forward to working you again soon.

Until next time…
