Conflict of Interest

The ARRL Ethics and Elections Committee has recused a director for publishing a book that competes with ARRL publications, creating a conflict of interest. I find this strange as ARRL is a non-profit amateur radio advocacy organization, not a for-profit company driven by shareholders’ financial interests. I thought, perhaps naively, the goals of ARRL publications were to promote and enable the hobby, and not primarily be a line of business or product offering that competes in the marketplace.

I find the framing of this really troubling, with the “ongoing conflict of interest” being caused “through the creation and publication of a book which competes with one or more ARRL publications”. If the book was published in the public domain and available for free, it still would compete with ARRL publications, and arguably would still be considered an ethics violation, despite such publication being totally altruistic and compatible with ARRL’s mission of amateur radio advancement. Such competition could perhaps also be claimed for publishing a website of antenna designs, or volunteering for a non-ARRL VE organization.

There is a conflict of interest here, however it’s ARRL’s interest in publication offerings that is in conflict with its primary mission of advancing amateur radio.

Most Active SOTA Summits in Colorado

Previously, I wrote that Mount Herman (W0C/FR-063) is the most radio-active summit in Colorado. Here is a fresh look at the data, with seven Colorado SOTA summits that have at least 100 activations. The W0C page on sotl.as is quite handy for viewing this information. Mount Herman still leads the pack by a wide margin, with many activations by Steve/WG0AT.

A view of Pikes Peak from Mt Herman.

Pikes Peak is still in second place but Genesee Mountain is essentially tied with it. Pikes Peak is a 14er but has a road to the top and most of those activations are probably aided by a vehicle. Genesee is a much lower, easy-to-access summit just west of Denver. Chief Mountain has edged out Mt Evans for fourth place.

The summit formerly known as Squaw Mountain has been renamed Mestaa’ehehe Mountain (W0C/PR-082). There is a gated road to the top so most activators hike that road.

Thorodin Mountain made the list as it seems to be gaining in popularity, with Carey/KX0R as a frequent activator.

Most of these summits are in the Front Range section of W0C, close to the major cities which aids their popularity. The other two are listed in the Park Range and the Sawatch Range, but they are also not far from the large urban areas.

First in North America

In North America, Mount Herman is second to Mount Davidson (W6/NC-423) which currently has 522 activations, many of them by Ellliot/K6EL. Davidson is a small summit in the middle of San Francisco, so it has easy access for a large population. This video by W6DFM provides a tour of that summit.

So that’s your update on SOTA activations in Colorado.

Topband’s Poor Winter Performance




A recent discussion on the Topband mailing list regarding the exceptionally poor propagation this fall and winter, especially on the polar path, brought forth some interesting opinions as to the reason. The rapid growth of solar Cycle 25 and its seemingly continuous flaring was the prime culprit ... but what was the exact mechanism? 

One of the best and clearest explanations was posted by Frank, W3LPL, who, with 317 countries confirmed on 160, knows a thing or two about propagation on topband! His comments are particularly relevant for stations in the northern regions of the US as well as for all regions in Canada. 

 "There's some confusion about the effects of increasing solar activity on 160 meter DX propagation.

160 meter DX propagation is often badly affected by nighttime propagation degradations, especially as Solar Cycle 25 becomes much more active from now through solar maximum in about 2024-2025 and as it slowly declines to current ionization levels through about 2027-2028.

Solar flares have no known impact on 160 meter DX propagation. Solar flares produce electromagnetic radiation that travels from sun to Earth at the speed of light - in about 8 minutes. Solar flare electromagnetic radiation (mostly X-rays) affects only the sunlit side of the earth and ionosphere. There are no known physical processes that extend solar flare effects into the night time ionosphere. 

While solar flares have no relevance to 160 meter DX propagation, solar flares often occur coincident with (but are not caused by) coronal mass ejections that can cause severe post-midnight absorption in the D region on propagation paths that cross the auroral oval (e.g., North America to northern Europe and Asia). CMEs cause the auroral oval to dip to much lower latitudes causing post-midnight increased D region absorption on propagation paths crossing lower latitudes.

Unrelated to CMEs, coronal hole high speed stream effects also cause increased D region absorption in the post-midnight auroral oval and occur very frequently compared to geo-effective CMEs (thankfully most CMEs never strike the Earth or its magnetosphere, they usually miss our tiny planet). 

But what about 160 meter absorption usually present much earlier in the night, from sunset through midnight and later? 

The E region usually retains enough ionization to degrade 160 meter night time propagation especially during the more active years of the solar cycle. The ionized night time E region causes increased absorption at the bottom of the E region (just above the D region) and blankets propagation that would otherwise pass through the E region to the F region. Blanketing causes many shorter hops that suffer increased loss from multiple lossy passes through the ionized E region. 

 73 Frank W3LPL"

I found Frank's comments regarding the auroral zone (highlighted in RED) particularly interesting as it confirms behaviors I have noted for several decades while operating from SW British Columbia ... particularly when it comes to the MF NDB band (200 - 530kHz). Time and time again while propagation on these frequencies has been severely degraded, stations just a few hundred miles (often less) to my south or south-east enjoy almost normal propagation. I've long-suspected that the AU zone has temporarily slipped this far south while my not too far away neighbours have escaped its unwelcome reach.

I have ALWAYS associated these poor conditions with signal absorption by a heavily-ionized D layer that has not dissipated after darkness but it seems a second factor may also be in play, that being from the E-layer as explained by Frank (highlighted in BLUE). 

Although CMEs and flares can cause a lot of disruption, the big culprit for the past few years has been an almost continual barrage of high speed coronal hole streams that have regularly killed nightime propagation on 80 and 40m as well.

With Solar Cycle 25 really starting to ramp up (three X-flares in the past two days!) it's very likely we will see poor propagation on topband as well as on the lower HF bands for the next few years. Some relief may be in store during the downslope ride as there is generally less flare and streaming activity during this period than on the ride up.

None of this eliminates periods of quiet geomagnetic conditions at any time, producing worthwhile propagation, particularly on the non-polar paths ... so don't turn off your radios!

Bonehead move on my part

 

With SPLIT on and not just DUAL

This afternoon I spent some time on the radio and I noticed on the DX Heat Cluster the DXpedition TK8N was being spotted in the CW portion of 15m. So over I went and there was a large pileup I thought it would be interesting to polish my skill in finding out how they were working the pileup.


 I set my Icom to dual receive which allows me to hear VFO A (the DXpedition station) in my left ear. In my right ear, it's VFO B ( the pileup). I wanted to see if I could figure out how he was working the pileup. Was TN8K moving up or down the band as he made contacts and was he moving in large or small increments? 


In time I figured out what TN8K was up to and I found myself on a segment of the band to which I was sure he was listening so I threw my call out and on the second time a very loud "VE9KK UP UP!!. I thought WHAT and I realized I was still in dual receive which is fine BUT I did not put my radio in SPLIT!!! 


I was transmitting my call right over the top of TN8K on his transmit frequency!! What a bonehead move.
