In response to the spaceweather.com article about a lack of sunspots I posted yesterday, SWLing Post contributor, Rob Wagner (VK3BVW), replies:
Oh Thomas! Really?
It’s not all doom-and-gloom, you know! The low-frequency part of the SW spectrum is proving very good value at the moment. And the mediumwave guys are telling me that there’s plenty of DX to be had in that part of the RF spectrum.
And yesterday, I had some FT8 success!
From southeastern Australia on a dipole with 5w getting into Plymouth, Minnesota on 14mHz in the mid-afternoon here. Not bad at all for the bottom of the sunspot cycle!
Ha ha! Thanks for your reply, Rob! Honestly, I wasn’t trying to spread doom-and-gloom, rather I was pointing out how low this sunspot cycle has gone. (Okay, so perhaps I was also shaking my fist at our local star!)
I completely agree with you Rob. It’s not all doom-and-gloom! Here are a few strategies for working DX during sunspot lows:
Sunspots really enhance propagation on the higher HF bands: especially 17 meters and higher. Without supspots, you’re not going to reliably snag serious DX on 10 meters, for example–there will be the occasional opening, but it might not last long. During sunspot cycle peaks, the higher bands provide outstanding DX opportunities even with a modest setup.
During one peak, I’ll never forget sitting in my car in North Carolina, with a RadioShack 10 meter mobile radio connected to a mag mount antenna, and having a three way chat with a ham in Sandiego, CA and one in Glasgow, Scotland.
With that said, even this year I’ve snagged some excellent DX on 17 meters (my favorite HF band). And, as you point out Rob, 20 meters is a great band for snagging serious DX even with no sunspots giving you a boost.
Openings between the US and Australia happen routinely on the 40 meter band as well, although some of us might have to wake up early or go to bed late to participate.
Of course all of this same advice applies for SWLing. Most of the DX I snag these days is found on the 25 meter band and lower. I’ve also been using this opportunity to explore Mediumwave DXing.
Kim Elliott and I had an exchange about this yesterday on Twitter. Some digital modes are so robust they seem to work regardless of propagation.
Kim knows this well as he receives reception reports from Shortwave Radiogram listeners across the globe each week.
If you’re a ham radio operator, I strongly encourage you to check out the latest “weak signal” digital modes: JT65 and, especially, FT8.
In fact, SWLing Post contributor, Robert Gulley (AK3Q), wrote an excellent introduction to these modes in the June 2017 issue of The Spectrum Monitor magazine.
Robert and I talk about the FT8 mode frequently. Since I discovered this mode at the 2017 W4DXCC conference, I’ve been hooked. Sure–it lacks the nuances of phone and CW, but it’s incredibly fun to watch my flea-powered signal acknowledged by someone on the other side of the planet with a flea-powered signal.
As Robert will tell you, FT8 seems to defy propagation theory. I agree wholeheartedly.
I’ve worked some of my best DX with this mode during the sunspot low and have never used more than 15 watts out of my Elecraft KX3 and KX2.
Don’t give up!
Use the sunspot low as an excuse to explore frequencies and modes you’ve never used before. Use this as an opportunity to improve your listening skills and the most important part of your listening post or ham station–your antenna system!
I regularly get email from people who’ve found the SWLing Post and take the time to write a message to me complaining about the death of shortwave radio: the lack of broadcasters, the prevalence of radio interference and the crummy propagation.
“Hey…sounds like radio’s not your thing!”
While this same person is moaning and complaining, I’ll be on the radio logging South American, Asian and African broadcast stations.
I’ll be working DX with QRP power, even though everyone tells me that’s not possible right now.
I’ll be improving my skill set and trying new aspects of our vast radio world.
You see: I’ve learned that the complainers aren’t actually on the air. They gave up many moons ago because someone told them it wasn’t worth it, or they simply lost interest. That’s okay…but why waste time complaining? Go find something else that lights your fire!
While these folks are complaining, I’ll be on the air doing all of the things they tell me I can’t do.
Rob, thanks for your comment!
“Weak” might also be confused with “not as many broadcasters as 20 years ago”. I can listen to the NHK in Japanese, FROM JAPAN, *not* Issoudun, here in FEMA Region 5 with just a good portable at night.*
*Shortwave only, not mediumwave at all
There can be some surprising openings at times, but you need to spend time at your radio to catch them. I’m currently having fun operating QRP SSB on my local beach. In the past week I have worked Russia, HK and Japan on 20 and 15 metres. Running a FT817 on 5 watts into a home made vertical wire up a squid pole. Best result was a 58 report into Tokyo. The other station was running a kilowatt and 5 element yagi! He was 9+10db. Sunspots are a factor for sure, but operating skill, studying the band characteristics in your location and good old luck play a part.
As a new ham (January 2018), I guess I just don’t know any better. I set up my new-to-me TS-450S(AT) about three weeks ago, and have been playing on 40 and 80, contacting stations all over the US and Canada, and several in Europe. The antenna is an inverted “V” OCF dipole at only about 32′ (apex), but apparently it works to some degree. 🙂 I do look forward to other bands opening up as the solar cycle progresses, but for now, I’m still going to have fun!
I wholeheartedly agree with all the good advice here and I’d like to add “go outsides, go places, nomad SWLs and hams are the coolest of them all and get the most out of their hobby”. 🙂
However I can understand how perception can make people buy the “doom and gloom” thinking, particularly those with little experience/experimentation. Think 80m ragchewers that were using the same QTH and antenna setup for decades and got encircled by new QRM sources over the years, and of course SWLs with bedside portables and all kinds of noisy antenna designs, who used to hear a lot on those in earlier years. For those, the decreasing signals and rising noise floors through increasing near-field and “propagated” local QRM look like extinction of their hobby. For the time being that is.
Doing some (not-so-quick) examinations through my log, I have worked right around 3000 contacts on weak signals modes since starting about mid January last year (and stopping due to antenna problems around November, with a little activity this last month). I have worked 140 countries from my location in the U.S., with roughly 35 of those being new DX entities for me, or basically new (meaning I might have one SSB contact but multiple weak-signal contacts). I have 33 newly confirmed LOTW contacts bringing my total to 164 LOTW confirmed.
My total number of actual DX contacts according to my log is 176. This list are those stations which were new or basically new to me because of the power of weak-signal mode software:
Ceuta and Melilla
North Cook Islands
Papua New Guinea
Republic of Korea
SAINT PIERRE & MIQUELON
South Shetland Islands
So, solar minimum? It’s not the end of the world, and shortwave is not dead either!
Amazing, Robert! Amazing!
I listen to RNZI every evening on 15720 and 11725 kHz. That’s a distance of 6,600 miles. I also hear NHK in the English language on 9860 kHz during my evenings. It is beamed from Italy into West Africa. What about BBC World Service last night on 9915 kHz? That’s from Woofferton 5,200 miles away. This is office chair suburban listening at its best with a horizontal loop antenna plugged into a Sangean 909X. I really should find a nice hidden place out of town tonight, roll out the spool of wire and tune in some real not-quite-at-the-bottom of Solar Cycle 24 DX.
