It’s not you, it’s the bands! (Also, see you at Hamvention!)

I’ve received a few messages from readers and subscribers about failed park activations over the past few days.

It’s no surprise, really, since we’ve had several extended periods of HF radio blackouts with powerful solar flares and CMEs bombarding our planet.

I experienced this firsthand on Sunday. We celebrated Mother’s Day with a picnic and hike at Tuttle Educational State Forest on our way to visit my father in the hospital in Hickory, NC.

I didn’t plan on activating, so I didn’t bring my radio pack or camera gear. I wanted the day to focus on celebrating my amazing wife. After we finished eating and before hitting the trail, everyone encouraged me to get on the air for a bit.

I didn’t have my radio pack, but I did have the Elecraft KH1 in my EDC pack. I went back to the car, grabbed it, and then started calling CQ POTA after spotting myself on 20 meters.

I only heard crickets. After 25+ CQ POTAs, not a single hunter responded. I knew conditions were terrible, but I figured I’d work at least one station. Nope!

I tuned around to try contacting one of the half dozen or so activators on the air, but I couldn’t hear any of them. In fact, I only heard one ongoing conversation on the entire 20-meter band. Even the FT8 frequency was quiet.

In fact, I only heard one rag chew in progress on the entirety of the 20 meter band. Even the FT8 frequency was pretty quiet.

If I had my radio pack (and my goal would have been to activate) I would have deployed a 40M EFHW and settled in for a very long activation. I’m sure I would have eventually worked 10 stations, but it could have taken a couple of hours or more.

All this to say, if you had a failed activation in the past few days, it’s not you. The HF bands have simply been dead at times.

I packed up the KH1 without making a single contact, which was fine because we were there for family time, and that part was absolutely amazing!

Hamvention 2024

I’m heading to Ohio today for the first leg of my journey to FDIM (Four Days in May) and Hamvention. I’ll be at FDIM all day Thursday and Thursday, Friday, and Saturday evenings.

At Hamvention, you’ll find me at the Halibut Electronics/Ham Radio Workbench Podcast booth #3011 when I’m not browsing the indoor and outdoor exhibits. Stop by and say hi!

Also, during Hamvention, I’ll have very little time to check email and comments, and I expect a backlog by the time I’m back home next Tuesday. I appreciate your understanding.

If you have a pressing question, please sign up for our discussion group at QRPer.net. There are loads of mentors there who can help you!

If you’re also going to Hamvention, travel safely!

Cheers & 72,

Revised prediction for Solarcycle 25 looks most promising

Revised prediction for Solarcycle 25

A revised prediction from the NASA High Altitude Observatory based at the University Of Colorado.

NASA Heliophysicists have released a revised prediction for Solar Cycle 25.

The report generated by Ricky Egeland a Solar Physicist working in the NASA Space Radiation Analysis Group now calls for the peak of Solar Cycle 25 to top out at a value of 195 ± 17 based upon the new scale for calculating Smoothed Sun Spot Number. For reference Solar Cycle 21 peaked at an SSN 233 (new scale) while Solarcycle 23 peaked at an SSN of 180 (new scale). If this predictions holds up Ham Radio will see Excellent Worldwide F Layer Conditions on 10 Meters for several years around Solar Max. 6 Meters conditions should be good in the Equinox Periods before and after Solar Max with consistent openings on Medium Haul Polar Routes. 6 Meter routes traversing the equator should experience consistent openings ± 9 months from Solar Max.

Ricky Egeland is a particpating member in the group headed up by Scott McIntosh and Bob Leamon that published a paper 9 months ago outlining the existance magnetic bands within the Sun that govern the Sunspot and Hale Cycles. At the time of its publishing the paper went on to predict the peak of Solar Cycle 25 could be as high Solarcycle 21. Today’s released is a revised prediction based upon data observed since the original paper was published. To be sure we are still in early days.

The Solar Rotation Cycle as marked by Sunspot Activity was established on April 19, 2021 so we are only 90 Days into actually observing Cycle 25 Activity. It is now agreed the dramactic run-up in Sunspot Activity we experienced late Last Fall while tied to Cycle 25 was an outlier. When asked directly about whether they can declare if the Terminator Event they wrote about in the Fall 2020 Paper has occurred Scott McIntosh stated “We can’t be sure just yet but we are very very close”. It also should be noted that while it has been over a year since the sun produced a Cycle 24 Region with a Sunspot worthy of a NASA Classification the Sun has been steadily producing Spotless SC 24 Active Regions the last of which formed right on the Solar Equator at N00-W54 on July 24,2021 as recorded by Jan Alvestad’s Solar Terrestial Activity Report Website. These Active Regions being part of a Solarcycle in its final stages of existence produce no spots and only last for a few hours before they dissipate away. The previous SC24 Active Region formed on June 28, 2021. Once the SC24 active regions cease forming Solar Cycle 25 will take off in earnest.

Sol food! Sunspot numbers on the rise.

According to a new article published by NASA, we may have finally hit the rock bottom of the Solar Cycle and are on our way to Solar Cylce 24.  According to sunspot forecaster David Hathaway of the NASA Marshall Space Flight Center, the recent sun spots groups that have appeared on the sun belong to Solar Cycle 24. This is an encouraging development since we have been dealing with the solar minimum for what feels like an eternity in QRP time (nearly 2 years, according to NASA). 

I’ve seen a lot of discussions on ham radio sites, in the ham press and in email groups about hams waiting to try QRP until the next sun spot cylce is in full swing. I don’t think this is necessary. In fact, I have been operating QRP throughout this lull and found that the solar minimum has had no effect on my daily/weekly QRP QSOs in the lower bands (160/80 & 40 Meters). I’ve also done some pretty respectable DX in the higher bands as well. Yes, those DX contacts are more rare, but it makes me appreciate each one even more. 

With that said, QRP will really come alive in the higher bands in a couple of years. There’s no better time to hone your skills than to be practicing when the going is tougher.   It’ll make you a better operator. I promise.

So, box up that amplifier and sell it on eBay. Then, find the power knob on your transceiver and turn it down until you barely notice the power output meter trembling–hit the air and have some QRP fun!
