I’m sure that you have heard of NPOTA, National Parks On The Air, and SOTA, Summits On The Air, and probably even POTA, Parks On The Air, The US program for the World Wide Flora and Fauna, but have you heard of the latest event that starts on Sunday, Dec 11, 2017?

Starting at 0000 UTC time on December 11, 2017 the new year long event celebrating multiple anniversaries for the NASA program will start. It is called NOTA or NASA On The Air.

With several NASA clubs doing several special event stations of the coming year, they decided to make a year long event where you, as the end user, can contact the stations to earn points through the year. You can even gets points during other events like Winter Field Day, the ARRL Field Day and others.

Losten to my latest podcast episode where I talk with Rob Suggs about it:

Here is the current forecast discussion on space weather and geophysical activity, issued 2017 Dec 07 1230 UTC.

Solar Activity

24 hr Summary: Solar activity continued at very low levels. Region 2690 (N07W23) decayed into a plage region. No Earth-directed CMEs were observed in available satellite imagery.

Forecast: Solar activity is expected to continue at very low levels over the next three days (07-09 Dec).

Energetic Particle

24 hr Summary: The greater than 2 MeV electron flux was at normal to high levels today with a maximum flux of 3,260 pfu observed at 06/1735 UTC. The greater than 10 MeV proton flux was at background levels.

Forecast: The greater than 2 MeV electron flux is expected to be at moderate to high levels for the next three days due to CH HSS influence. The greater than 10 MeV proton flux is expected to continue at background levels for the forecast period.

Solar Wind

24 hr Summary: Solar wind parameters indicated the continued influence of a positive polarity CH HSS. Solar wind speed decreased from approximately 635 km/s to near 525 km/s over the period. Total field ranged from 2 to 6 nT while the Bz component was between +3/-5 nT. Phi angle was oriented in a mostly positive solar sector.

Forecast: Solar wind parameters are expected to continue to be enhanced under a positive polarity CH HSS through day one. A slow return to nominal levels is expected on days two and three as HSS effects wane.

Geospace

24 hr Summary: The geomagnetic field was quiet to unsettled.

Forecast: The geomagnetic field is expected to be at quiet to unsettled levels on days one and two, followed by mostly quiet levels on day three as CH HSS effects diminish.

This Saturday night as well as the next will be the annual Bruce Kelley 1929 QSO Party, otherwise known as the '1929 BK'.





Only transmitters that are 'era-appropriate' are allowed to be used. More specifically, transmitters must employ tubes that were available in 1929 or earlier, and transmitters must be self-excited. No crystals allowed! Crystals were new and largely unaffordable for most hams back in the depression days.

1929 marked a real turning point in amateur radio as governments finally cracked-down on things such as frequency stability, out of band operations and re-alignment of call districts. In short, hams were henceforth required to behave themselves and to clean up their signals and methods of operation.

Although the new rules did a lot to improve things when it came to 'signal purity', there was still a long way to go ... but the wheels of improvement had been officially set in motion. The next decade would see monumental changes in both transmitter and receiver architecture, as engineers along with some particularly gifted amateurs, strove to unlock the challenges of this relatively new technology.

If you tune across the CW bands during the next two Saturday nights, you will have the rare opportunity to hear exactly what the bands must have sounded like back in the early '30s'.

For the most part you will hear single tube Hartley, Colpitts or TNT oscillators along with a few two-tube MOPAs thrown in. Many of them will suffer the same problems encountered by the boys of '29 ... chirp, drift, buzzy notes and frequency instability from antennas swaying in the wind.

This year, signals should be a little louder as well, since the previous power limitation of 10W input has been increased to 25W.

The MOPAs will sound much better but some surprisingly nice-sounding signals can be heard coming from properly tuned and optimised single-tube oscillators. I recall being blown away by the lovely sounding signal I heard from such a rig when first tuning into the BK activity several years ago, only to learn that it was a self-excited Hartley using 1/4" copper tubing for the oscillator tank circuit!

The '29 watering-hole on 80m will be around 3550-3580 kilocycles (be careful not to confuse this with kilohertz!) while the early afternoon to post-sunset 40m activity will be found from 7100-7125 kc. There may even be a few on the very low end of 160m. Although many of these transmitter styles were used on 20m and higher, BK rule-makers have wisely decided not to inflict these sounds on the present populace as it would likely keep the 'Official Observers' busy for several days writing pink-slips.

You can learn more about amateur radio happenings leading up to and following the 1929 crackdown in my earlier series of 'Why '29' blogs here:

Part 4

Building '29-Style - Part 2

Heck, there me even be time to throw something together for the following Saturday if you have a few parts and an older tube or two ... the '27 comes to mind and is readily found in many junk boxes. Maybe you know an old-timer or two with lots of parts that could help you out.

Let's hope for good conditions for this event as the last few years have been adversely affected by geomagnetic storming. Poor propagation or not, I guarantee there will be plenty of '29ers busy calling 'CQ AWA' on the low bands.

Joyce/K0JJW and I had intended to hike Pikes Peak this year for a Summits On The Air (SOTA) activation but somehow the plan never came together. I still had my eye on it as a drive-up activation before the end of 2017. The road to the summit is open year round now but closes frequently due to snowstorms passing through. Saturday morning the road was open to 13 miles (out of 19 miles) with the promise that it would be open to the summit later in the morning. (Call 719 385-7325 for a recorded message on road conditions.) By the time we got to the toll gate around 10 am, the road was open to the summit.

When we reached the summit, the weather conditions were 20 deg F with 20 mph winds, creating a windchill of 4 deg F. We were prepared for that having loaded up on the winter clothing. Still, it was freaking cold up there. As you can see in the webcam picture, there was only traces of snow on the summit.

To be SOTA-compliant, we had all of our gear loaded into our packs and walked some distance away from our vehicle to set up. Because of the wind, we chose the observation platform, tucked in behind one of the walls. Normally, that platform is to be avoided because its overrun with tourists but with the cold weather we only had a few people to contend with.

Joyce set up on 2m fm (146.52) using a handheld transceiver (HT) with a vertical antenna. Even with her headset (foam protection on the microphone), the wind noise on her signal was significant. I started out on 2m fm but quickly moved up to 223.5 MHz and worked a few stations there, then on to 446.0 MHz. I had HTs and small yagi’s on both of those bands. Then I fired up 1.2 GHz with an Alinco HT (just 1W on that band) and a 16-element yagi. I worked Paul/W0RW, Gary/WB5PJB and Wayne/N0POH on that band. My QSO with N0POH in Aurora was a new personal best for distance on 23cm/1.2 GHz, at about 90 km.

I tried 2m SSB using my FT-817 but made only one contact: Jim/WB0GMR. Shortly thereafter, I switched back to 2m fm using the 25W mini-mobile rig with a 3-element yagi to work many more stations. Again, just running a bit of power and having a decent antenna on 2m fm was very effective at making radio contacts. I expected the Tytera radio to be overloaded with signals on the summit of Pikes but it actually held up well with just occasional bursts of interference.

Overall, we made 54 QSOs (not too shabby): 43 QSOs on 2m, 5 QSOs on 70cm and 3 QSOs on both 1.25m and 23cm. Our best DX was Jeff/N0XLF near Akron, CO for a distance of about 130 miles (on 2m and 70cm).
