Endfed vs Nor’easter!

My Endfed antenna was put up on October 2nd with a few issues that I blogged about but mostly have been sorted out. Today was the test to see how it held up with some strong winds, today was the arrival of a Nor'easter here in the Maritimes. There was high winds and lots of rain, I did find that as it continued to rain the SWR on 40m could not be tamed by the LDG antenna tuner. All other bands were just fine. I was outside at one point when the rain slowed a bit to take out some trash. The one end of the antenna is just outside the back shed and I gave the Endfed wire a bit of a pluck like one would do to a guitar string. Water came off the entire Endfed antenna. I went back into the house and gave 40m a go again and all was well. I'm guessing a collection of water on the antenna affected 40m and I imagine over time more water would had affected the other bands.
Now back to wind vs Endfed antenna, the 9:1 balun enclosure is mounted in a tree with the other end mounted at the shed. Before putting up the antenna I had to devise a way of overcoming the tree sway  and the stress it would put on the antenna. I thought about using a spring but when I went to the hardware store here in town there were none  I felt would flex before any stress was placed on the antenna, the springs just had to have to much tension before they would start to flex. A comment I received on my blog regarding this very issue was to use bungee cord. These were easy to come by at the hardware store and I decided to use it. My installation consisted of 2 bungee cords just incase one became effective and let go.
Today as the wind gusts picked up I noticed the tree that the 9:1 balun was on was swaying a lot but the bungee took up the flex and allowed the Endfed to hardly even move. Up to this point in time the Endfed only had to deal with a slight breaze but today it was put to the test and it passed without issue.

First SOTA Activation of W0C/SP-020 (Talus)

While looking for our next SOTA adventure, I noticed a never-been-activated, unnamed 13er (W0C/SP-020) to the west of Mount Princeton. I checked various maps and it looked like there was a 4WD forest service road that went up to the adjacent saddle.  So Joyce/K0JJW and I decided to give it a try.

SP-020 as viewed from the saddle (and parking spot).

We took County Road 306 west out of Buena Vista, towards Cottonwood Pass. Then we turned left onto County Road 344 which goes to Cottonwood Lake. We continued past Cottonwood Lake until we found FS 348, also known as Hope Gulch Road. We followed this road for 5 miles to the saddle.

This graphic shows the 4WD road in red and the hiking route in purple.

The road was easy-peasy 4WD, no problem at all with our stock Jeep Wrangler. A Suburu-class SUV can probably make it but there are a few rocky spots on the road that will require special care. There were two water crossings, one of them with about a foot of water (across Cottonwood Creek).  Now this was mid-October, so the streams are not running real strong. Earlier in the year, this could be a major hazard.

Warning: water crossing at Cottonwood Creek.

FS 348 is single lane, with long stretches without an easy passing or turnaround spot. We were happy that we only saw two other vehicles on the road.


We drove a bit past the saddle (where there is a small hut/cabin) and parked where a closed side road heads off toward the summit. We hiked up this closed and then vectored off towards the summit. The hike was only 0.6 miles and 800 vertical feet. However, there was quite a bit of talus to climb over which really slowed us down. The hiking route does not seem critical but following the top of the ridge seemed to be good.

Near the top, we encountered lots of talus.

Yeah, about the talus. It isn’t any worse than other rocky summits in Colorado but it seemed to catch our attention, usually in the form of “ok, I’ve just about had it with this talus.” A contributing factor was that both Joyce and I had foot/ankle injuries in recent years. So our unofficial name for this summit became Talus.

Joyce/K0JJW took the honors of completing the first SOTA activation of this summit by contacting Bob/W0BV on 2m FM. We also both logged these stations: KD0MRC, W0RW, W6JM, W0LSD and N0AJN.

We sat there quite a while just taking in the view. Mt Princeton is due east; Mt Antero and Mt White are to the south.

You never know what your gonna get on the first activation of a summit. On this one, it turned out to be a fantastic day. The weather was sunny, temperature about 40 degrees, a little too windy at times. Late in the season, we didn’t have to worry about thunderstorms moving in and blowing us off the mountain. I liked the combination of a good 4WD road, heart-pumping but not-too-difficult hike, a first-time SOTA activation and doing it all with my favorite hiking partner (and wife).

Weekly Propagation Summary – 2019 Oct 14 16:10 UTC

Weekly Propagation Summary (2019 Oct 14 16:10 UTC)

Here is this week’s space weather and geophysical report, issued 2019 Oct 14 0407 UTC.

Highlights of Solar and Geomagnetic Activity 07 – 13 October 2019

Solar activity was very low. The solar disk was spotless. No Earth-directed coronal mass ejections (CMEs) were observed.

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit was at moderate levels on 08-13 Oct and at high levels on 07 Oct. The maximum flux of the period was 1,930 pfu observed at 07/1745 UTC.

Geomagnetic field activity ranged from quiet to active levels. The period started off at nominal levels with solar wind speeds in the 350-405 km/s range. by 09 Oct, total field increased to 11 nT at 09/2135 UTC followed by an increase in solar wind speed to approximately 490 km/s as a weak negative polarity coronal hole high speed stream (CH HSS) moved into geoeffective positon. Solar wind speed remained enhanced through late on 11 Oct. The geomagnetic field responded with quiet to active conditions on 09-10 Oct and quiet to unsettled levels on 11 Oct.

Forecast of Solar and Geomagnetic Activity 14 October – 09 November 2019

Solar activity is expected to continue at very low levels.

No proton events are expected at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit is expected to reach moderate levels on 16 and 24 Oct and again on 04-09 Nov. High levels are expected on 14-15 Oct and on 25 Oct-03 Nov due to recurrent CH HSS influence.

Geomagnetic field activity is expected to reach unsettled levels on 14-15 Oct due to possible weak CH HSS effects. Unsettled to active levels are expected on 21 Oct and 24-28 with G1 (Minor) geomagnetic storm levels likely on 24-25 Oct due to recurrent CH HSS effects.

My first contact as VE9KK

Well once the headphones were repaired and I ran through the starting of the radio software and making sure it was speaking politely to the radio I was off to try my hand at FT8. I was calling CQ on 20m and on Hamspots my call was being spotted in Europe and I was thrilled! Back at my condo QTH in Toronto I was only spotted in the U.S. and there was a spot in Iceland as well. It was not long at all until IU8DON from Italy answered my CQ call on FT8!! I was amazed that my signal was making it finally across the ocean. I did not have to much time after the sorting of the software and radio communication testing but the contact with Italy just made my day!

Homebrew Hero 2019 Announced

The Homebrew Heroes Award Program announced its first annual recipient, Hans Summers, Call Sign G0UPL. The recipient is the very popular proprietor of QRP Labs and maker of numerous homebrew style projects in amateur radio. He’s been producing them for over a decade now. The details are available at this link, including a video of the award to Hans.
Hans G0UPL Hero 2019
Being involved with launching the Homebrew Heroes Awards Program with Martin Butler M1MRB and Colin Butler M6BOY on the Steering Committee has been exciting as we’ve been very busy with development since the idea hatched at Xenia Hamvention this past May. But the payoff is seeing the impact that such attention can bring to a most deserving recpient, like Hero 2019 Hans Summers. “I am just blown away by it all!” said Hans when he received the plaque and customized clothing designating him as Homebrew Hero for 2019. This annual award recognizes persons, groups or organizations who help define the frontiers in amateur radio technology through the long-standing tradition of “home brew” construction. This is the first of the annual awards to be given by the new program, housed at the website address, homebrewheroes.org. A video of the award is available here. A longer feature interview with Hans is available in Episode 308 of the ICQ Podcast which is the promotional partner of the Award Program.
