The Most Radio-Active Mountain in Colorado
I’ve often said that Mount Herman (W0C/FR-063) is the most (ham) radio active mountain in Colorado. Many of us have operated from that summit for VHF contests, QRP events and Summits On The Air (SOTA). Of course, I didn’t have any data to back that claim…until now. A review of the cumulative SOTA activations in Colorado through Jan 1, 2016 shows these four summits as the most-activated SOTA peaks.
Summit | SOTA Designator | Number of Activations |
Mount Herman | W0C/FR-063 | 95 |
Pikes Peak | W0C/FR-004 | 53 |
Mount Evans | W0C/FR-003 | 33 |
Squaw Mountain | W0C/PR-082 | 31 |
All of these summits are relatively close to the large population centers in the state. Also, they not that difficult to get to and some of them have roads that go to the top. Pikes and Evans are both 14ers but can be accessed via 2WD vehicles.
But what makes Mount Herman so special? It does not have a road to the summit — you definitely have to hike it, a little bit more than a mile one way with elevation gain of ~1000 feet. What makes the difference for Herman is that it is in the backyard of the well-known radio ham, goat hiker and SOTA enthusiast, Steve WGØAT. Steve has personally activated the summit more than 30 times AND he drags along mentors encourages other radio hams to join him. Frank KØJQZ did 22 activations, some with Steve and many on his own. (Frank just achieved SOTA Mountain Goat status, activating enough summits to earn 1000 SOTA points.) Fortunately for me, Mt Herman is about 4 miles as the GPS flies from my house, so I have worked that summit 31 times (usually Steve or Frank and always on 2 meters). I’ve also activated Mt Herman for SOTA three times, as described here: A Soggy Mount Herman SOTA Activation, Mt Herman: SOTA plus VHF Contest and Winter Assault on Mt Herman.
Here’s one of Steve’s fun videos that captures the first SOTA activation of Mt Herman, with his goat crew Peanut and Rooster (SK).
Frank and Steve, thanks for all of the Q’s from Mt Herman over the past years! See you on the air and on the trail.

Weekly Propagation Summary – 2016 Jan 04 16:10 UTC
Here is this week’s space weather and geophysical report, issued 2016 Jan 04 0534 UTC.
Highlights of Solar and Geomagnetic Activity 28 December – 03 January 2016
Solar activity ranged from very low to moderate levels. Very low activity was observed on 03 Jan, low level activity on 29 Dec – 01 Jan, and moderate level activity on 28 Dec and 02 Jan. Region 2473 (S22, L=331, class/area=Fkc/590 on 26 Dec), which exhibited a complex beta-gamma-delta configuration, produced all of the significant flare activity (2 M-class, 14 C-class).
On 28 Dec, Region 2473 produced an M1 flare at 28/1245 UTC. Associated with this event was a Type IV radio emission and a partial-halo CME observed off the southern portion of the disk, first visible in LASCO coronagraph imagery at 12/1212 UTC. Analysis of this CME determined that an Earth-directed component was present.
On 02 Jan, Region 2473 produced a long duration M2 flare at 02/0011 UTC. Associated with this event were Type II (1095 km/s) and IV radio emissions and an assymetric partial-halo CME observed off the southwest limb, first visible in LASCO coronagraph imagery at 01/2324 UTC. Analysis of this CME determined that a weak Earth-directed component was present and would arrive around midday on 03 Jan, though eventually proved to be a miss.
There was greater than 10 MeV proton event on 02 Januaury 2016. The event began at 02/0430 UTC shortly after a long duration M2 flare that accured at 02/0011 UTC. Proton flux reached a maximum flux value of 21 pfu (S1-Minor) at 02/0450 UTC and ended at 02/0750 UTC.
The greater than 2 MeV electron flux at geosynchronous orbit was at high levels throughout the period with the exception of 31 December when moderate flux levels were observed. A maximum flux of 6,782 pfu was observed at 03/1600 UTC.
Geomagnetic field activity ranged from quiet to moderate (G2) storm conditions. At 31/0003 a small shock was observed at the ACE spacecraft. Total field (Bt) increased from 5 nT to 13 nT with a corresponding solar wind speed increase from 350 km/s to 500 km/s. The shock was associated with the arrival of the 28 Dec CME observed in LASCO C2 imagery at 28/1212 UTC. Isolated G1-Minor to G2-Moderate storm conditions were observed midday through late on 31 Dec as well as early on 01 Jan. Mostly quiet conditions were observed on 28 – 30 Dec, 02-03 Jan.
Forecast of Solar and Geomagnetic Activity 04 January – 30 January 2016
Solar activity is expected to be at low levels with a chance for M-class (R1-R2, Minor-Moderate) flare activity from 15 Jan – 28 Jan due to the return of Region 2473 (S22, L=331). Very low solar activity is expected for the remainder of the period.
No proton events are expected at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit is expected to be high from 04 – 13 Jan, 25 – 30 Jan due to recurrent coronal hole high speed streams (CH HSS).
Geomagnetic field activity is expected to be at active levels on 04, 07, and 22 Jan with G1-Minor storm conditions on 06 Jan due to recurrent CH HSS activity. Mostly quiet to unsettled levels are expected for the rest of the period.

Winter update from KG9DW
Welcome to 2016! Lots of big projects are going on here at the radio ranch. My youngest is working on an arduino powered weather station that will be located at the FFA field plot along US51 north of Heyworth. We’re going to get the data from the site using the AREDN ham radio mesh software. It’s a real cool project, and my daughter is doing a great job with the programming.
I finally got all of my coax run into the shack in a decent fashion, and I’ve got coax switches in place to be able to toggle between the two hf rigs and the two hf antennas. My next antenna will either be an hf beam, or I’m putting up a sky loop. Or maybe another windom positioned north to south. Who knows!
I played with the Yaesu Wires-X software and an HRI-200 box this past week. I hooked it to a Motorola CDM-1550 mobile radio. I really like these Motorola radios – great receive, easy to interface, and just all around bullet-proof. These are the same radios I’ve used for two D-STAR repeaters…hard to beat. Anyway, I’ve got the Wires-X setup on a UHF simplex channel linked into the Central Illinois room. Wires achieves the same as a D-STAR reflector, just done a different way. I’m running Wires in analog mode, and so my analog audio is digitized at my computer and sent on to the server running the room. From there it goes to whoever else is joined into the room. If someone is running Wires in digital mode, the audio comes out digital. If you’re running analog, it comes out analog. I’m not sure if I’m going to hook this into our Heyworth analog machine, or if I’m just going to keep it as a simple simplex node (a hotspot in D-STAR speak).
We’ve got a DR-1X repeater coming to Heyworth to replace the Kenwood TKR-820 the club has up on the elevator. The big benefit for us will be to replace the old Kenwood that sometimes has problems in warm weather, along with getting rid of a crazy long squelch crash. The new repeater arrives on Tuesday, and I’ll let it burn in for a few weeks (or months depending on the weather) before it goes up on top of the elevator.
That’s it for now…have a great year everyone!

NPOTA: ARRL’s Best Idea?
The National Parks on the Air (NPOTA) is off and running. Making contact with a handful of stations currently operating from NPOTA locations has made me wonder if the ARRL has had a good idea with NPOTA as a way to help celebrate the anniversary of the National Park Service.
From ARRL: “Throughout 2016, Amateur Radio will be helping the National Park Service celebrate their 100th anniversary. Hams from across the country will activate NPS units, promote the National Park Service and showcase Amateur Radio to the public.”
I am a huge fan of both the National Parks and the National Park Service. Anyone who is interested in the history of our National Parks would be well rewarded to start with the Ken Burns documentary The National Parks: America’s Best Idea. Yellowstone generally gets credit for being the first National Park back in 1872. However, the National Park Service was not established until 1916. That period in between provides us a very good reason that there are times when we need a government organization to protect us from ourselves. During that in between period, the Army was given the mission of attempting to protect both Yellowstone and Yosemite. Like most missions the Army received, they were underfunded, under equipped, and undermanned. They did, however, do the best they could to protect these amazing areas. Many Americans saw these new National Parks as areas for economic exploitation. If it wasn’t for many individuals working long and hard for the establishment of the National Park Service, it is very likely we would not be able to enjoy the parks we have today. Stephen Mather and Horace Albright were the two primary individuals who secured the establishment of the National Park Service. Ken Burns talks about these two individuals in his documentary and there are also a few books that do a great job telling the story (Creating the National Park Service: The Missing Years and The Birth of the National Park Service: The Founding Years, 1913-33).
The National Parks exist for our enjoyment. Generally that enjoyment manifests itself in some type of hiking, camping, fishing, watching for wildlife, or learning about history. This interaction between Park and citizen can be passionate, emotional, revitalizing, inspirational, and an educational experience.
With all that being said, I was a bit surprised to hear stations making contacts for NPOTA locations like it was a contest. Each NPOTA location is identified by a letter-number combination. No discussion of where they actually were. No description, no discussion. It is a bit sad to see there is a Leader Board – which only facilitates looking at NPOTA as a contest rather than an actual celebration.
I also wonder how these activations are impacting those non-amateur radio enthusiasts who are visiting a NPOTA site. Is this putting amateur radio in the best light?
Are these NPOTA activations promoting the National Park Service or showcasing Amateur Radio to the public?
If so, how?
What would Stephen Mather and Horace Albright think about NPOTA?
It will be interesting to see how NPOTA progresses over the coming weeks and months.

GW3UEP 630m Transmitter Tweaks
DF8UO's GW3UEP 630m Tx |
From Daniel's test data, it looks as though the IRF540's are quite happy as long as you keep the transmitter at 100W or less ... anything higher would certainly benefit from the switch to IRF630's as the high efficiency is maintained at least to the 300W level. Something at this level would no doubt benefit from higher-voltage capacitors and heavier inductors as well as a little more heatsinking, enough to shed at least 25 watts of heat between the two FETs.
Daniel drives his amplifier with an Ultimate3, followed by a 10db attenuator, a squarer and into the totem pole driver stage. His own version uses toroidal inductors rather than the original air wound coils.
A pair of GW3UEP amplifiers using IRF630's at ~40V into a small power combiner, should provide ~550W of useful output at >90% efficiency ... more than enough power to do some serious work on 630m.
