Weekly Propagation Summary – 2019 May 13 16:10 UTC

Weekly Propagation Summary (2019 May 13 16:10 UTC)

Here is this week’s space weather and geophysical report, issued 2019 May 13 0226 UTC.

Highlights of Solar and Geomagnetic Activity 06 – 12 May 2019

Solar activity was at low levels on 06, 07, and 09 May due to C-class flare activity from Region 2740 (N08, L=307 class/area Dho/280 on 05 May. The largest of the flares was a C9.9/1N at 06/0510 UTC. Mutliple eruptions were observed in coronagraph imagery, but only the halo CME from 06 May was geoeffective. The assymetric halo CME was first observed in SOHO LASCO C2 imagery at 06/2348 UTC. Additionally, a partial halo CME was first observed in LASCO C2 imagery at 12/2036 UTC and is determined to be Earth-directed and arrive at Earth on 17 May. Solar activity was at very low levels for the remainder of the summary period.

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit reached high levels on 07, 11, and 12 May. Normal to moderate levels were observed throughout the remainder of the period.

Geomagnetic field activity reached active to G1 (Minor) storm levels on 11 May due to the arrival of a CME from 06 May. Impact was first observed by the DSCOVR spacecraft at 10/1655 UTC. Total reached a peak of 12 nT and Bz reached a maximum southward deflection of -11 nT. Solar wind averaged near 350 km/s throughout tranient passage. G1 (Minor) storm levels were observed during the 11/00-03 UTC synoptic period, with several active periods during the remainder of the UT day. Quiet to unsettled levels were observed for the remainder of the period.

Forecast of Solar and Geomagnetic Activity 13 May – 08 June 2019

Solar activity is expected to be at very low levels, with a slight chance of C-class flares throughout the period.

No proton events are expected at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit is expected to be at moderate to high levels on 13-23 May, and 29 May – 08 June. Normal to moderate levels are expected on 24-28 May.

Geomagnetic field activity is expected to reach G1 (Minor) storm levels on 15 and 17 May due to CME arrival. Active conditions are expected on 29 May due to the influence of a recurrent coronal hole high speed stream. Quiet to unsettled conditions are expected for the remainder of the period.

Benchduino: It’s Gonna Be BIG, for Builders

By Rube Goldberg – Originally published in Collier’s, September 26 1931, Public Domain, https://commons.wikimedia.org/w/index.php?curid=9886955

Far more than will admit, amateur electronic builders tend to have a prototype that looks more like a Rube Goldberg cartoon than something designed by Hewlett Packard (when they were building). Me, too. There’s just a lot of wires, connectors, rigged-up jigs, and so forth when you’re trying to get a circuit to work like it’s ‘sposed to. And, put a microcprocessor or small PC board into the mix, aye yai yai!

There are breadboards, even sophisticated ones, that help with this. And, there are design boards to facilitate with some PIC development as well as ones that help with Arduino or Raspberry Pi projects. That’s good. But I’ve seen nothing like a workbench platform for most all of these with hardware and software hooks to keep Rube Goldberg in Collier’s Magazine. Until now.

George Zafiropoulos KJ6VU of the Ham Radio Workbench Podcast team has put together what he calls the Benchduino. George has an Internet group on the project at Groups.io here. You can follow the beta development there by joining. But you can get more meat on the bones by listening to a recent episode of the HRW podcast on the Benchduino. If you build using microprocessors, you will not be disappointed.

This product will be BIG for builders. You can download the interim documentation file here. Here’s what it looks like, taken from the website page. There are multiple add-on boards to connect to Arduino Mega, Raspberry Pi Zero, PIC – 40 pin 18F series processor, Adafruit Feather, Xbee data radio socket (built-in). George has pre-loaded shopping carts for necessary parts at Digi-Key for various boards. To channel the comedian Martin Short: I must say, I must say!

Benchduino Prototype

Taken from the HRW website page:

The BenchDuino is a development platform for building projects based on the Arduino, Raspberry Pi and PIC microcontrollers. The platform defines a common foot print for processor and expansion boards to make it easy to expand the functionality of the system. The BenchDuino motherboard includes many commonly used peripherals which can be connected to the CPU pins with jumper wires or plug in shunts. The BenchDuino is an open platform and we encourage the development of plug-in CPU and expansion boards.

https://www.hamradioworkbench.com/benchduino.html

Now, this is quite dramatic for prototype development using various microprocessor boards. But the pièce de résistance, IMHO, comes via the header on the top edge of the Benchduino as shown in the photograph above. Need several pieces of test equipment, including a logic analyzer, to check out whether your code makes the light blink (or whatever)? Use the Analog Discovery 2 USB-based test workbench directly connected to the Benchduino! I love mine, including the latest add-on Impedance Measurement Board (~$20). The HRW Podcast has a $100 off discount code for the AD2 product through their website which takes you to Digilent.

So, in brief, your project doesn’t have to be a Rube Goldberg cartoon that you’d just not like your builder buddies to see before it’s completed. Your project may not get Bob’s Your Uncle status upon first execution, but it will likely be Bob’s Cousin with the Benchduino and the Analog Discovery 2. The latter has multi-platform free software for the hardware which makes it a Swiss Army Knife of test equipment.

I’m buying my Benchduino boards from the Ham Radio Workbench booth at Hamvention this year. George is giving a Forum talk / demo on the Benchduino too. (Digilent will also be at Xenia with the HRW discount. Get the Impedance Analyzer Board while you’re at it.) Let George know you’re coming via Twitter: @kj6vu

From Sea to Summit on CW

I've now been an Amateur Radio Operator for 30 years. There isn't much about the hobby that I don't like. For me and many in the hobby, radio is magic and however we experience it, by definition makes it magical. However, there are always a few experiences in the hobby that you just have to talk about and I recently had one of those experiences. Did I work my last country, no. Did I win a contest, no. Did I build a complete home-brew station, absolutely not. I suppose I've given it away with the title of this story, but I recently experienced of couple of aspects of the hobby that I enjoy in the same week and I thought it worthy of mention.

I've enjoyed the IOTA program for 25 years. It took me 16 years to get to #1 DXCC, but I'm still working new ones in IOTA. There are 1200+ island groups so it takes a while. I've also enjoyed IOTA Expeditioning over the years including islands in  Australia, Nicaragua, Labrador, Alaska and numerous islands in the Gulf of Mexico. My last expedition was in 2017 and I was getting the itch to go out again.

I live about 3 hours from the Gulf of Mexico and had been thinking about a trip to North Padre Island, (NA-092), on the Texas coast to have a fun couple of days operating portable and enjoying the National Seashore there. I was convinced that while NA-092 was not rare in the states, the RV Ham crowd has satisfied that demand, but that it would be needed in Europe and Asia. To convince myself that I needed to take the radio gear on the trip, I put out a query on the IOTA Chaser reflector to gauge interest. I was a bit surprised at the many long time IOTA Chasers in Europe and Asia who needed it. So, my hunch was confirmed.

So I put my operating plan together. My station would consist of:

K3 Transceiver
KPA500 Amplifier
KAT500 Tuner
30 ft MFJ push up pole
MFJ 2980 Feather Lite Vertical
Begali Stradivarius Paddle
N1MM+
Winkey

Since Padre Island is a barrier island it is connected to the mainland by a bridge, so no boat necessary on this trip. I have a tear-drop camping trailer that is a king-size bed on wheels with a kitchen in the back which would be sleeping quarters and a 6 person tent which would be the operating HQ. My XYL, Cris, accompanied me on the trip and was gracious enough tolerate my operating. Below is a picture of the operating location.

AD5A/p on North Padre Island
My operating strategy was to focus on European sunrise and Asian sunset on 40m, which means operating through most of the night and early morning. This was also a CW only expedition. CW is my preferred mode by a 9.9 to 1 margin. I brought a nice, heavy, Begali paddle with me so I could feel right at home.

I was very pleased with the results of the operation. I provided a new island to many EU and Asian Chasers and the station performed well. I was very pleased with the performance of the Feather Lite vertical. The antenna has a very small foot print, which in a campground is essential, and I experienced good TX/RX results with it, of course a vertical over salt water works extremely well and this was confirmed once again. During the first Asian sunset, 3:30 am for me, I had to go split for about an hour to handle the pile-up. I finished with 633 QSO's with ~40 countries, 427 of the QSO's were on 40m.

But this is only half the story. We arrived on Padre Island on a Monday afternoon and departed on Wednesday morning.

On Friday, we had to catch a flight to Albuquerque, NM and drive to our second QTH in Santa Fe, NM. One of my favorite things to do in Santa Fe is to do activations for the Summits on the Air (SOTA) program. In Santa Fe we have a team we call the Three Amigos, consisting of Fred, KT5X, John, K1JD and myself. We are all Mountain Goats within the SOTA program, (1,000 activation points required) and our likeness was captured by a female artist, the subject of another blog. But here is our portrait, notice the belt buckles if you can see them:

Tres Amigos de SOTA


Upon arrival in Santa Fe, I made contact with John, K1JD (KT5X as out of town) and we decided to activate El Cerro de la Consena or W5N/SI-020 which had an elevation of 6,923 ft. This mountain has lots of loose rock and cactus.

Planning for a SOTA activation is much simpler than an IOTA expedition, but you will need to be self propelled. This hike is ~6.5 mile round-trip. My station consisted of a KX-2, a 3 band trapped EFHW made of 28 ga. wire, an 81 to 1 transformer and a 20 ft. collapsible fiberglass pole. The paddle I use is the Elecraft paddle made for the KX2 I made 28 QSO's on this activation and found these:

Hopi Petroglyphs
The next day I did a solo hike to Peak 9420, at oddly enough, 9,420 ft ASL. This summit is only about a 2 mile round trip, but has a nice operating position on the summit. As you can see from the picture it is within an Alpine region and it is a beautiful hike. I made 38 QSO's from here.

AD5A Shack at 9,420 ft

So in the span of a week I had gone from Sea Level to Mountain Summits operating CW and enjoying the magic of our hobby. There is adventure in ham radio, and many ways to get out and make QSO's. If you can't make QSO's at home, go to where the QSO's are, the seas and summits.

On t’fells

Whilst the weather may not have been as warm as last year at this time it has been a very dry few weeks so I have taken the time to get out on the fells and do a few SOTA activations. Nothing too demanding but the local ones around Wasdale and a visit to Keswick.

Keswick can offer a few things. Skiddaw and Blencathra are the two in the frame today. It also offers swarms of people in expensive technical clothing wandering round the town and people on the fells in flip flops. Skiddaw is popular as you can walk from the town. Both of these walks were up and back the same way. A bit dull I know but they can both be very busy if you leave it past about 9am

Both of these walks I had Angus (the dog by the way) with me to keep me company / attempt to pinch other peoples sandwiches. They are nice enough walks but can be a bit busy so if it is solitude you’re after avoid these. There were kids playing in the remains of the snow on the steep slopes in bare feet!

Next up was a trip to Wasdale. Well to be specific it was Mosedale in Wasdale to start with but Pillar and Kirk Fell were the targets. The route take you up black sail and is quiet. You can go up the very steep slope to the left to Pillar but it’s hard going and not as quick as you might think. Pillar is a lovely spot, great views across Ennerdale and Wasdale and on a good day over to Keswick and out towards Penrith. We had a small refusal from Angus at the top of Kirk Fell, where the red splodge is. There is a steep slippery section with some 2+m bits of scramble. He couldn’t get up so we turned round and went round Boat How. Much gentler and less likely to involve Mountain Rescue.

Lastly in this section was Great Gable and Scafell Pike. I’ve not been up Great Gable for a couple of years and it was nice to go up via Sty Head tarn and then up to the war memorial on the summit. It started to snow on the top and was still snow just a few hundred meters from the tarn. Carry straight on and that takes you along the corridor route up Scafell Pike. Quieter and less eroded. There are alwways a few odd sights up on the summit, from people who look like they are going to collaspe through to runners bagging the summit. Best to use the small remains of the hut just below the summit on the south side for activations.

The summits were cold that day and the valley reasonably warm and free from wind, there were some very cold looking people on the summit and at least one dipstick who forgot a patch lead, so no hf activation for me!

I’ve not been over to Helvellyn so that might be next on the list list for this year. Plenty of time to get out and about if the weather stays like this. There were a few dried up tarns and I wonder if this is a result of last summer when it was nearly 30c in Wasdale.

The total so far for SOTA is 198 points. A long way off mountain goat but enjoying the time on the fells all the same.
