Weekly Propagation Summary – 2019 Jul 15 16:10 UTC

Weekly Propagation Summary (2019 Jul 15 16:10 UTC)

Here is this week’s space weather and geophysical report, issued 2019 Jul 15 0223 UTC.

Highlights of Solar and Geomagnetic Activity 08 – 14 July 2019

Solar activity was at very low levels throughout the reporting period. Region 2744 (S27, Lo=209, class/area=Bxo/020 on 07 Jul) decayed to played by 08 Jul. A coronal dimming was observed in SDO/AIA 193 beginning around 14/0030 UTC from near the vicinity of old Region 2744 (S27W46). A subsequent CME signature associated with the event was observed in SOHO/LASCO C2 imagery beginning at 14//0236 UTC. The slow-moving, narrow and faint signature from the SW limb was modeled and the resulting WSA-Enlil output suggested no Earth-directed component was present.

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit was at normal background levels on 08-09 Jul. An increase to moderate to high levels, in response to activity from a negative polarity CH HSS, was observed on 10 Jul and persisted through 14 Jul.

Geomagnetic field activity ranged from quiet to G1 (Minor) geomagnetic storm levels. An abrupt enhancement from a possible transient was observed at 08/1829 UTC. Total field increase from 4 to 10 nT and solar wind speeds increased from 300 km/s to a brief peak of 400 km/s resulting in an isolated period of active conditions. Late on 09 Jul, the onset of a positive polarity CH HSS increased wind speeds to a peak of 663 km/s and total field to 13 nT. G1 storm conditions followed a period of sustained southward Bz with values reaching as far south as -11 nT at 09/1845 UTC. A final period of G1 storm conditions was observed early on 10 Jul as influence from the CH HSS persisted. Quiet to unsettled levels on 11 Jul transitioned to quiet through the end of the reporting period as the solar wind returned to nominal levels.

Forecast of Solar and Geomagnetic Activity 15 July – 10 August 2019

Solar activity is expected to be at very low levels over the outlook period.

No proton events are expected at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit is expected to range from normal background to high levels. High levels are expected from 15-18 Jul and 06-10 Aug; moderate levels are expected on 19-21 Jul; the remainder of the outlook period is expected to be at normal background levels. All enhancements in electron flux are expected due to the anticipation of multiple, recurrent CH HSSs.

Geomagnetic field activity is expected to range from quiet to active levels. Active levels are expected on 15-16 Jul and 05-06 Aug; unsettled levels are expected on 17 Jul, 28 Jul, 04 Aug and 07 Aug; the remainder of the outlook period is expected to be at quiet levels. All increases in geomagnetic activity are due to the anticipation of multiple, recurrent CH HSSs.

2019 Colorado 14er Event

August 3 & 4, 2019
Saturday and Sunday
www.ham14er.org

Amateur Radio operators from around Colorado will be climbing many of Colorado’s 14,000-foot mountains and Summits On The Air (SOTA) peaks to set up amateur radio stations in an effort to communicate with other radio amateurs across the state and around the world. Join in on the fun during the 28th annual event and see how many of the mountaintop stations you can contact. The covers the entire weekend but many mountaintop activators will hit the trail early with the goal of being off the summits by noon due to lightning safety concerns.

The event includes all Summits On the Air (SOTA) summits, which adds over 1700 potential summits! If you aren’t up to climbing a 14er, there are many other summits to choose from with a wide range of difficulty. See the Colorado SOTA web page at w0c-sota.org

Radio operators who plan to activate a summit should post their intent on the ham14er group via the ham14er groups.io website. Also, be sure to check out the event information at http://www.ham14er.org

Frequencies used during the event
Activity can occur on any amateur band including HF and VHF. The 2m fm band plan uses a “primary frequency and move up” approach. The 2m fm primary frequency is 147.42 MHz. At the beginning of the event, operators should try calling on 147.42 MHz. As activity increases on that frequency, move on up the band using the 30 kHz steps. Don’t just hang out on 147.42 MHz…move up! The next standard simplex frequency up from 147.42 MHz is 147.45 MHz, followed by 147.48 and 147.51 MHz.

For a complete list of suggested HF, VHF and UHF frequencies see this web page.

Warning: Climbing mountains is inherently a dangerous activity.
Do not attempt this without proper training, equipment and preparation.

New Homebrew Heroes Award…

Ridgeland, Mississippi— July 8, 2019— Today, the ICQ Podcast (icqpodcast.com) announced a partnership in the founding of the Homebrew Heroes Award by three members of the podcast. This annual award is to recognize persons, groups or organizations who help define the frontiers in amateur radio technology through the long-standing tradition of “home brew” construction. It is housed at the separate website, homebrewheroes.org.

“We felt that with all of the technical homebrew activity in amateur radio today that there should be a means by which to identify and highlight those whose technical creativity has made a clear impact on the hobby,” said Frank Howell, K4FMH at ICQ Podcast (icqpodcast.com). “Our recent visit to the Hamvention conference in Xenia, OH convinced us that the traditional homebrew craft and science is alive and well,” said Martin Butler, M1MRB from London. “But there was no clear means to bring additional and independent attention to the fruits of their labor,” added Colin Butler M6BOY, of County Kilkenny, Ireland. “My background in strategic marketing and information technology led me to believe that the time was right for such an award,” he added. Howell stated, “If you look at some of the workbenches for many successful homebrew entrepreneurs, their equipment is vintage, to say the least, so our awards program may assist them in getting corporate support through donated products to enhance their future ability in this maker-space.”

The new awards program is independent of the ICQ Podcast but these three podcast members comprise the Steering Committee for the annual award. These include Martin Butler M1MRB, Colin Butler M6BOY, and Frank Howell K4FMH. The ICQ Podcast is a promotional partner in this endeavor while the Homebrew Heroes website is maintained by Howell. “The idea for this awards program originated while we attended, for the first time, the Hamvention in Xenia, OH. It struck the three of us that this was another way to give back to the hobby,” said Martin Butler.

Other podcasters in the homebrew electronics maker space have applauded this new program. Jeremy Kolonay KJ7IJZ, co-host of the wildly popular Ham Radio Workbench (hamradioworkbench.com) said, “When I heard about this new award program, I was very excited. The homebrew electronics community in amateur radio has grown tremendously as our biweekly podcast has attempted to track and encourage. It’s really important to have a way to recognize and promote excellence achieved by the most successful participants.”

“Commercial companies have begun signing on to donate prizes to the future recipient,” said Howell. “Digilent Inc., a National Instruments Company, immediately told us that they would contribute their highly successful Analog Discovery 2 test device. Kaitlyn Franze, Software and Hardware Product Manager with Digilent, said, “When I learned that this was being planned, I immediately said that Digilent would like to be a corporate prize sponsor. Our market base has been significantly impacted by amateur radio operators who design and build equipment in this maker space. Digilent is proud to be on board with the Homebrew Heroes Award Program.” Other companies have expressed positive interest and are evaluating the right product to donate. Howell added, “We anticipate that this donor list will grow with the awareness of the awards program.”

Founded in 2008, ICQ Podcast (icqpodcast.com) is one of the more successful amateur radio podcasts in the world. It is published every two weeks and has a team of a dozen international presenters on the podcast, based in the United Kingdom.

Weekly Propagation Summary (2019 Jul 08 16:10 UTC)

Here is this week’s space weather and geophysical report, issued 2019 Jul 08 0205 UTC.

Highlights of Solar and Geomagnetic Activity 01 – 07 July 2019

Solar activity was at very low levels throughout the reporting period. Region 2744 (S27, Lo=207 class/area=Bxo/20 on 07 Jul) only produced several low-level B-class events and appears to have a reverse polarity magnetic configuration.

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit was at normal background levels.

Geomagnetic field activity transitioned from unsettled early on 01 Jul to quiet for the remainder of the reporting period. A weak enhancement in the solar wind on 01 Jul was obscured by intermittent mag data from L1.

Forecast of Solar and Geomagnetic Activity 08 July – 03 August 2019

Solar activity is expected to be at very low levels 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 moderate levels from 11-14 Jul due to influence from a positive polarity CH HSS. The remainder of the outlook period is expected to be at normal background levels.

Geomagnetic field activity is expected to range from quiet to active. Active levels are expected from 09-11 Jul in response to influence from an anticipated positive polarity CH HSS. Unsettled levels are likely on 28 Jul due to a SSBC. The remainder of the outlook period is expected to be at quiet levels under a nominal solar wind regime.

VHF SOTA Near Fairbanks

Joyce/K0JJW and I were planning a trip to Alaska to visit several of the national parks. We had some time available while in Fairbanks to do some SOTA activations. We were traveling very light, so we took minimal SOTA gear: a pair of VHF/UHF handhelds and simple antennas.

The lightweight VHF/UHF SOTA outfit: Just a pair of Yaesu FT-1DR handheld transceivers, spare battery and basic antennas (rubber duck and RH 770).

We used my newly-fashioned antenna mount on a trekking pole we had with us. The trekking pole served us as as a trekking pole for hiking, a camera monopod and now an antenna support. It provides a handy way of supporting a vertical antenna and provides a little more antenna height when held up in the air.

The trekking pole with antenna mount attached. An RH 770 antenna attaches to the BNC connector on top.

I checked the SOTA database to identify easy-to-access summits near Fairbanks. There are several 1 and 2 point summits in the area with easy access. We were not looking for drive-up summits but we did want an easy hike.

I found that Dale/KL7R and Peter/K3OG had been activating in the area, so I contacted them via email and they both gave me helpful advice. We were a bit concerned about getting our four QSOs on VHF, but that turned out to not be a problem. We worked Dale from all three summits and he helped rustle up a few more stations to work. We had pretty good luck just calling CQ on 146.52 MHz. And I announced our presence and need for simplex contacts on the KL7KC repeater (146.88 MHz, 103.5 Hz tone).

We activated three summits:

Chena Ridge (KLF/FN-205)

We drove up Chena Ridge Road, then took a gravel road uphill towards the summit (I think it was labeled North Becker Ridge Road). At this point, we encountered a locked gate and parked there. Some locals wandered by and said that they hike up to the top every day, so come along. The hike was easy, less than one quarter of a mile with some elevation gain. At the summit is an FAA VOR site enclosed by a chain link fence.

Pedro Dome (KLF/FN-164)

Next, we drove north out to Pedro Dome, which has a substantial radio site on top. We took Steese Highway north from Fairbanks to Pedro Dome Road, a gravel road that goes right to the top of the summit. There are opportunities to make a wrong turn on the way up Pedro Dome Road but with a little care we were able to drive to the top. Despite the fact there are plenty of radio transmitters on the summit, we did not experience any interference on 2m and 70 cm. That summit has an excellent radio horizon, so it was easy to work stations in the Fairbanks area.

Bob/K0NR holds the trekking pole with RH 770 antenna attached, on Pedro Dome. The radio site is visible in the background.

Wigwam Benchmark (KLF/FN-204)

Wigwam Benchmark is a summit that pokes up just north of Fairbanks. It is a bit more difficult to navigate because it in a rural residential area with lots of twisty-turny roads. I plugged “Noel Drive, Fairbanks, AK” into google maps, which got us very close. Then we drove to where Noel Drive meets Mia Drive and operated from the road. The area is heavily wooded and we did get attacked by the famous Alaskan mosquitoes, so we made our radio contacts and escaped quickly.

Summary

At one point, I told Dale that if we made one contact from one summit, we would be happy. But, of course, we tried for more than that and got it. It turned out to be a great day running around these summits near Fairbanks and making some radio contacts. Thanks to KL7R and K3OG for the assistance!
