The Fall “Classic Exchange”

W7OS - Radio Club of Tacoma working the CX
This fall's running of the CW "Classic Exchange" will take place on Sunday, September 23 and on Tuesday, September 25. The following week will see the Phone "Classic Exchange", on Sunday, September 30 and on Tuesday, October 2.

The "CX" encourages participants to use older vintage gear including any homebrew equipment, both receivers and transmitters. A unique scoring system provides bonus points for various equipment and combinations as well as encouraging 'repeat contacts' when you switch to different equipment.

W8KM and his wonderful vintage station

No vintage gear? ... no problem! All amateurs are invited to participate and get in on the fun no matter what they are using and submit their scores.

K3MD's Heathkit AT-1 and Hallicrafters HT-37 ready for the CX

The CX is a low-key relaxing affair and the 'extra' Tuesday operating period should encourage a lot of midweek activity from the vast numbers of retired operators who cherish and run older gear.

Lots of combos ready at W4BOH's CX setup

K6ZI, Las Vegas - WWII ARC-5s ready to go

For complete details, see the web site announcement here.

If you've never entered the Classic Exchange, why not give it a try this year as it truly is a case of 'the more the merrier' ... and eastern operators, make sure to keep the porch light on for us out west!

SOTA Activation from Teton Pass (W7Y/TT-122)

While exploring northwest Wyoming, Joyce/K0JJW and I were looking for a suitable mountain for a Summits On The Air (SOTA) activation. A little bit of research identified Pass Benchmark (W7Y/TT-122) as a good option. This summit is accessed from the Teton Pass trailhead, which is on a paved road (Route 22) heading west out of Jackson. There is substantial parking available at the pass and it appears to be a popular trailhead for hikers and mountain bikers.

Bob/K0NR and Joyce/K0JJW hanging out on the summit of TT-122.

The sign at the trailhead refers to this summit as Mount Elly, but I have not found that name on any of my maps or other sources. SOTA refers to it as “Pass Benchmark”.

Teton Pass sign
The sign at the Teton Pass trailhead shows an overview of the trails in the area.

We hiked south from the pass on an obvious gated road which later turns into a trail. We encountered several groups of hikers and mountain bikers so the trail definitely gets used and is in good shape.

The red line is our actual hiking track, which shows a few switchbacks not indicated on most topo maps.

We followed the trail past a radio site (and checked out the various antennas). The good news is the radio site is not on the SOTA summit, so not much chance of radio interference.

A typical section of trail.

We continued south on the trail until we were due west of the summit. There is a marker there for the Black Canyon Trail, which leads off to the south. Don’t follow this trail, instead turn left (east) towards the summit. A few switchbacks will get you to the top in good shape. The one-way distance for the hike was 2 miles with 750 feet of elevation gain. Very pleasant.

On top, we started calling on 146.52 MHz with the Yaesu FT-90 putting 30W into a 3-element yagi antenna. We both worked Sam/WY7EM, Jim/K7AVL and Mick/W7CAT on 2m fm. We also caught WY7EM and W7CAT on 446.0 MHz.  Thanks for the QSOs!

Weekly Propagation Summary – 2018 Sep 10 16:10 UTC

Weekly Propagation Summary (2018 Sep 10 16:10 UTC)

Here is this week’s space weather and geophysical report, issued 2018 Sep 10 0413 UTC.

Highlights of Solar and Geomagnetic Activity 03 – 09 September 2018

Solar activity was at very low levels this period. Region 2721 (N10, L=286 class/area Bxo/010 on 09 Sep) emerged near center disk on 08 Sep. This small region exhibited slight growth early on 09 Sep, but was showing signs of decay as of this report and remained inactive.

On 09 Sep, a prominence eruption was observed off the SW limb, beginning at 09/0815 UTC in SDO/AIA 304 imagery and at 09/0824 UTC in 171 imagery. While this event appears to be directed well south and west of the Sun-Earth line, significant gaps in SOHO coronagraph imagery data made analysis nearly impossible.

No proton events were observed at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit reach high levels on 03 – 08 Sep, then decreased to moderate levels on 09 Sep. A peak flux of 12,435 pfu was observed on 03/2035 UTC.

Geomagnetic field activity was at quiet to unsettled levels from 03 – 09 Sep, with an isolated period of active conditions on 05 Sep, likely due to a negative polarity coronal hole. Solar wind speeds began the period near 325 km/s, increased to over 500 km/s on 05 Sep and 07 Sep, and ended the period near 400 km/s. Total field strength averaged near 5 nT, and saw a peak of 11 nT on 07 Sep. The Bz component was variable through the period and saw a maximum southward deflection of -6 nT.

Forecast of Solar and Geomagnetic Activity 10 September – 06 October 2018

Solar activity is expected to be at low levels throughout the outlook period, with a slight chance for C-class flare activity.

No proton events are expected at geosynchronous orbit.

The greater than 2 MeV electron flux at geosynchronous orbit is expected to be at moderate to high levels through period. Moderate levels are expected from 10 – 12 Sep and again from 29 Sep – 06 Oct. High levels are expected from 13 – 28 Sep.

Geomagnetic field activity is expected to be at quiet to active levels on 10 Sep. Conditions are then likely reach G2 (Moderate) geomagnetic storm levels on 11 Sep due to a positive polarity coronal hole high speed stream (CH HSS). G1 (Minor) geomagnetic storm levels are also likely on 12 Sep as CH HSS effects persist. Active levels are expected on 13, 14, and 22 Sep from the influence of recurrent CH HSSs. Field activity is expected to be at quiet to unsettled levels throughout the remainder of the outlook period.
