Topband’s poor winter performance
The rapid growth of solar Cycle 25 and its seemingly continuous flaring was the prime culprit.

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.
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.

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.

CQ Magazine Article on Sherwood Tools
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.

Day one of 2023!!
Well, it's day one of 2023 and I am relaxing with my mid-morning coffee. I say mid-morning as for us retired folks who usually hit the sack around 10 pm venturing into midnight is a once-a-year endeavour. So a bit of sleeping in was in order. No hangover here as we just enjoyed a bottle of champagne to help welcome in the New Year. As for overindulging never did it. I never wanted to waste the next day with the booze flu.
As for 2023, I want to keep on my CW adventure as 2022 was a great learning curve for the art of CW. I find it kept my mind sharp, kept me occupied and always a new skill levels to master.
In 2023 I would like to master....or let's be more realistic and say get a grip on CW head coping for QSOs as I have always wanted to do this.
One thing in 2022 that lacked was my reading.
I want to put more time toward reading both technical, fiction and the magazines I subscribe to. All related to ham radio and to mix it up with some not!
One dream of mine has been vinyl records, a turn table and Jazz music all mixed together!
Finally just to continue with my CW contesting and learn more about technique, how to effectively handle a pileup and continue to have fun.
Happy New Year to my readers and all the best to your health and ham radio adventures.
