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.

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.

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.

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.

In the January 2023 issue of CQ Magazine, there is an article I wrote introducing my Sherwood Tools page over at FoxMikeHotel.com. Didn’t make the cover but it is on page 50! It will introduce the reader to these new tools to further utilize Rob Sherwood NC0B’s test suite of bench measurements on over 50 years of radios. I appreciate Rich Moseson (CQ Editor) for wanting to further publicize these online tools that I’ve created with the significant assistance of Rob Sherwood NC0B. He is an international treasure to the amateur radio community!

I update this webpage as I’m able to digest and process new data from Rob’s Table. It does take some time for me to reanalyze these data segments, as even one new entry alters the patterns and analysis from the previous dataset. If I am in the midst of other matters, it can take me a month or more to get to this update. (Amateur radio is a hobby, not a lifestyle, for me, lol.)

This work on price, performance and satisfaction with HF radios has been very popular over the past couple of years as I’ve given many talks to groups via Zoom on the studies and results. The first results from this line of research was published by (then) Editor Scott Wright K0MD at the National Contesting Journal. I’ll be adding the latest Yaesu HF radios (FTDX10 and FT-710) to the mix soon.

Stay tuned because I’m completing the analysis of a subset of these modern transceivers that includes composite transmit noise base upon data from a group of European amateurs complemented with measurements by Rob Sherwood NC0B. I’m completing that work and associated manuscript in the coming weeks.
