Weekly Propagation Summary – 2018 Oct 08 16:10 UTC
Here is this week’s space weather and geophysical report, issued 2018 Oct 08 0135 UTC.
Highlights of Solar and Geomagnetic Activity 01 – 07 October 2018
Solar activity was very low this period. Region 2723 (S08, L=357, class/area=Dso/30 on 01 Oct) was the only active region with sunspots, but was quiet throughout the period. No Earth-directed CMEs were observed during the summary period.
No proton events were observed at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit was at moderate levels throughout the period.
Geomagnetic field activity reached G1 (Minor) geomagnetic storm levels on 07 Oct due to the influence of a positive polarity CH HSS. Active conditions were observed on 01-02 Oct and quiet to unsettled levels were observed on 03, and 05-06 Oct. Quiet conditions prevailed on 04 Oct.
Forecast of Solar and Geomagnetic Activity 08 October – 03 November 2018
Solar activity is expected to be very low throughout the outlook period.
No proton events are expected at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit is expected to reach high levels on 08-25 Oct with moderate flux levels expected throughout the remainder of the outlook period.
Geomagnetic field activity is expected to reach G1-G2 (Minor-Moderate) geomagnetic storm levels on 08 Oct and 03 Nov due to the influence of a positive polarity CH HSS. G1 (Minor) geomagnetic storm levels are expected on 19 Oct and active levels are expected on 09-10, 18, 20, and 22 Oct, due to the influence of multiple, recurrent CH HSSs.

Some Summer Short Wave Listening
courtesy:americanradiohistory |
Over the past few months I’ve spent some time tuning around the international shortwave bands.
I vividly recall how jam-packed these bands were when I first discovered the magic of radio, back in the peak years of Solar Cycle 19. Much has changed in this part of the radio spectrum since then, but after having read so many dire comments describing the demise of international SW broadcasting, I was pleasantly surprised at what I discovered.
Although there are certainly not the large numbers of stations there once were, there is still a large amount of activity to be found throughout the various bands allocated to international SW broadcasting.

Trying to keep track of station schedules and frequencies is a hobby unto itself but now made easier with the availability of so many online information sources. As when younger, I found the best way to stay organized was to keep a SW logbook, eventually settling on a simple ‘diary’ format which is still evolving.
Its next refinement will be an additional notebook having separate pages devoted to each individual frequency within a given SW band. This will allow for updating frequency information from various postings of the daily online ‘heard’ reports.
I’ve always had a great interest in QSLs and collecting cards was one of the things that initially attracted me to SW radio back as a pre-teenaged DXer. For me, not much has changed in the last several decades and I still enjoy QSLs ... the real, traditional cards, as opposed to the now popular e-card. For me, an e-card just doesn’t have much appeal for some reason but for many others, they work just fine.
As I slowly re-learn much of what I had forgotten about SWL’ing, I discovered that there are still many SW broadcasters that will acknowledge a reception report with a real paper card ... just like the good old days!
If you are keen on doing some serious listening, I cannot recommend the WRTH highly enough.
Studying the latest WRTH revealed the QSL policies of most international as well as domestic SW broadcasters as well as contact information. It is a superb annual reference and well worth the investment! With this information in hand, my listening has become more focused on recording and submitting reception reports to those stations still practicing the courtesy of acknowledging reports with a traditional QSL. Many stations also issue an e-card, but these are of little interest to me at present.
With a small amount of spring-summer time devoted to SW listening, I generated and submitted a few reception reports along with linked audio files on my website ... so far, the following QSLs have arrived:
Radio Exterior de Espana |
15520 kHz - Noblejas, Spain |
Radio Free Asia |
9950 kHz - via IBB on Tinian Island, S. Pacific |
All India Radio (AIR) |
9865 kHz - Bengaluru, India |
DX Clube Sem Fronteiras Broadcast via WRMI 7730 kHz, Miami |
T8WH - 9965 kHz Palau, South Pacific |
HSK9 - 5875 kHz Udon Thani, Thailand |
Radio Liangyou - Hong Kong |
9275 kHz via Bocaue, Philippines site |
Radio Romania - 9730 kHz - Bucharest, Romania |
Radio Nikkei 2 |
3935 kHz - Chiba, Japan |
I’ll do an upcoming blog on some of the great information and online sites to support international SW listening activities.

A new antenna using single atoms
We may be on the verge of so-called “atomic radio,” thanks to the development of a new type of antenna capable of receiving signals across a much wider range of frequencies (more than four octaves) that is highly resistant to electromagnetic interference.

Tracing the Development of the AM Broadcast Transmitter
John F. Schneider W9FGH
In the Beginning, there was King Spark. There were a few early attempts at using spark equipment to transmit the human voice. This was because a spark signal consists of a continuous sequence of decaying waves, called “damped waves.” The signal faded in intensity as the energy of each spark dissipated, until it was replaced by a new signal from the next spark. In the early 1900s, there were only two devices that were capable of generating a continuous wave – an arc transmitter and a high-frequency alternator. But it was the invention of the “Audion” triode vacuum tube by Lee de Forest in 1906 that created a revolution in radio communications. Its ability to function as both an oscillator and amplifier opened doors to the creation of a practical all-electronic speech transmitter. John takes a detailed look at the evolution of the AM broadcast transmitter.
Has it Really Been a Decade!?
By Troy J. Simpson W9KVR
There’s nothing easy about teaching school anywhere but teaching, coaching, keeping a school amateur radio club going, being a dad and a husband makes time really fly. So much so that Glenn Raymond Middle School teacher, Troy Simpson, hadn’t realized their club station license was already up for renewal until he received the notice from the FCC. Troy recaps just the last few years of this very active and successful amateur radio school club as he prepares this month for another School Club Roundup.
SDR Report Part 3: From High-End SDR Receivers to SDR Transceivers
By Thomas Witherspoon K4SWL
Part one of our series on Software Defined Radios (SDRs), which appeared in the June issue, focused on the nomenclature and components of a functioning SDR system. Part two, in the July issue, took a look at some affordable SDR station options that would propel you into the world of SDRs for less than $200 US. This month, Thomas dives a little deeper into the SDR rabbit hole, and investigates higher-end SDRs as well as ham radio transceivers with embedded SDRs that include high-ticket rigs that have intel-agency specs and capabilities you won’t find in any analog radio at any price.
A Visit to the Tokyo Ham Fair 2018
By Keith Baker KB1SF/VA3KSF
Once again, Keith was asked to join the Dayton Amateur Radio Association team in a trip to Japan to attend the annual Tokyo Ham Fair, which is sponsored by the Japan Amateur Radio League (JARL). As Secretary-Treasurer of AMSAT North America, Keith would be doing double duty during this trip. And, as a regular contributor to TSM, Keith nailed the trifecta with this photo essay of that trip. Keith renewed many old acquaintances, got up close and personal with new ham equipment and enjoyed handing out goodies to everyone he saw.

Weekly Propagation Summary – 2018 Oct 01 16:10 UTC
Here is this week’s space weather and geophysical report, issued 2018 Oct 01 0253 UTC.
Highlights of Solar and Geomagnetic Activity 24 – 30 September 2018
Solar activity was at very low levels throughout the period. Region 2723 (S08, L=356 class/area Dro/030 on 30 Sep) developed on 29 Sep, but was already showing signs of decay as of this report, and remained inactive. No Earth-directed CMEs were observed in available satellite imagery.
No proton events were observed at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit reach high levels on 24 – 28 Sep, then decreased to moderate levels on 29 – 30 Sep. A peak flux of 6,202 pfu was observed on 24/2020 UTC.
Geomagnetic field activity was at quiet to unsettled levels throughout the entire period, from 24 – 30 Sep, under very subtle CH HSS influence. Solar wind speeds averaged near 430 km/s through most of the period, but did see an increase to reach a peak of 505 km/s on 30/0158 UTC. Total field strength ranged between 1 nT to 7 nT, while the Bz component was variable between +/- 6 nT through the period.
Forecast of Solar and Geomagnetic Activity 01 October – 27 October 2018
Solar activity is expected to be at very low levels throughout the outlook period, with a slight chance for C-class flare activity.
No proton events are expected at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit is expected to be at moderate levels from 1 – 8 Oct, and again from 26 – 27 Oct. High levels are expected from 9 – 25 Oct following elevated solar wind speeds associated to recurrent CH HSS activity.
Geomagnetic field activity is expected to be at quiet to unsettled levels from 1 – 6 Oct, with isolated active levels likely on 1 Oct. Conditions are then expected to reach G1 (Minor) storm levels on 7 – 8 Oct, with G2 (Moderate) storm levels likely on 8 Oct, due to a positive polarity CH HSS. A brief return to unsettled levels is likely on 9 Oct, with G1 (Minor) storm levels likely returning on 10 Oct as CH HSS effects persist. Active levels are expected on 11 Oct as CH HSS effects taper off. Mostly quiet to unsettled levels are expected from 12 – 18 Oct, with isolated active periods likely on 14 and 18 Oct. G1 levels are likely again on 19 Oct as another CH HSS influences the magnetic field. Isolated active periods are expected early on 20 Oct before conditions decrease to be at mostly unsettled levels throughout the remainder of the outlook period (21 – 27 Oct) as CH HSS effects continue to wane.
