Digital Revolution Or Evolution?

courtesy: KD0WTE



A recent reflector posting tended to confirm a rather intriguing trend that I have also been noticing over the past few years.



The poster lamented the fact that he often found very few or even no CW / SSB signals on the HF bands while at the same time seeing lots of activity throughout the digital portion of the bands.

It does seem like there is far less CW and phone activity on the HF bands now, than there was a few years ago and there is no question that digital activity has soared. Whether it's RTTY, PSK31, JT65, WSPR, JT9 or others, these digital signals are always prominent and, band plan or not, are slowly migrating further in the band as activity increases ... but is this the reason for the decline of traditional modes?

The digital weak-signal modes make these extremely popular for a number of reasons. Nowadays, many amateurs are living in antenna-restricted communities and are forced to develop smaller, lower and less effective stealthy antenna systems if they wish to get on the air and make contacts. Most of these modes perform well with minimal amounts of power and are capable of hearing well into the noise ... and unless you live out in the country, with well-separated neighbours, we all know that noise is increasing at horrific levels almost everywhere. These two factors alone might well explain much of the growth in digital activity.

Licencing requirements have also been slowly evolving and today, getting a ticket is much easier than it was several decades ago ... and in many cases, without the requirements of knowing anything about CW. Every month, North Americans see a large number of new amateurs, many with no code skills and possibly not much interest in acquiring them. From my own local observations, most of these new amateurs usually head straight to FM on the VHF/UHF bands and have little knowledge of or interest in HF radio. These factors must also play into the demise of activity on the traditional HF modes as well.

We also shouldn't overlook the influence that Old Sol is having on our HF bands as well. Solar Cycle 24 (begun in 2008) has been one of the poorest on record and continues to generate month after month of terribly poor HF propagation. As a young SWL who listened in Cycle 19, (the largest on record), I can vouch for the relationship between HF activity and good propagation. Those were amazing days, when 20 and 15m would stay open all night long ... even 10m would often still be open with F2 propagation at midnight towards VK and ZL! Everyday, month after month, the bands were simply bulging with activity, from end to end ... high solar flux numbers bring high activity numbers and we are now experiencing the downside effects of what happens when the sun dreadfully underperforms. The only exception to band-bulging activity today seems to be limited to major contest weekends only. Where these people go the rest of the time is a mystery.

There are surely other reasons as well for the gradual decline of traditional-mode HF activity, including the fact that the general ham population is getting older. Large numbers of stations are simply 'going away' as interest or opportunity declines and as more of the aging traditional-mode ops go 'SK'. I know of several hams that have just given-up because of insurmountable increases in their local noise floors. Our new and usually younger hams, have largely grown up in the 'digital age' and for those that do find themselves exploring the HF bands without CW skills, might logically settle into the digital modes first.

Things are changing quickly, of that there is no doubt. Last summer, on 50mHz, I noticed a large increase in the number of dedicated CW operators moving to JT65 and JT9 during openings and this summer has already seen another huge migration from one mode to the other.

Although this year's Sporadic-E season is just getting started, I have already heard many more countries on JT65 than I have on the traditional modes (Japan, Philippines, China, Formosa, Alaska, Venezuela, Cuba, Brazil). Yesterday I listened to a PY calling CQ on CW for some length, with no takers, while it seemed most of the usual west coast ops were watching the digital band. I fear that many good QSO possibilities will be lost as more stations switch to the much slower digital modes ... on 6m, many of the openings last for a very short time making CW or SSB the quickest way to complete a contact. The other problem I notice this summer is that there are several JT sub-modes and it is often difficult or impossible to figure out which mode is being used let alone having the time to switch to the other mode before signals are gone ... perhaps a case of having too much of a 'good thing'? Hopefully one mode will emerge as the '6m standard' so all are on the same page.

What will be the long-term outcome of these changes remains to be seen but I suspect we'll see more and more of our HF CW and SSB spectrum space gradually shrinking to make room for more digital activity, likely to become the dominant modes eventually.

As a life-time, almost exclusive CW operator since age 15, I find this somewhat disheartening but must admit that over the past few years, I have found my own level of weak-signal digital activity increasing by leaps and bounds. These are powerful, capable modes and offer amateurs new and exciting challenges from VLF to nanowaves. Are they as exciting as my much-loved CW? Ask me in a couple of years!

TSM Reviews: Yaesu FTM-100 DR: Amateur Friendly Digital Operating
By Mark Haverstock K8MSH

In 2013, Yaesu developed System Fusion, a format that retains backwards compatibility for analog along with FDMA-based digital communications. With the FTM-100DR, Yaesu has managed to create an affordable radio that integrates both analog FM and their C4FM digital modes into one package that accommodates digital users, while still keeping the analog FM crowd connected.

Early Radio Broadcasting: Publicity Stunts and Unusual Broadcasts
By John Schneider W9FGH

In the early years of radio, broadcasters were eager to explore the frontiers of the medium and found themselves in a continual series of “radio firsts,” similar to modern attempts to make it into the Guinness Book of World Records. To attract listeners, early stations sought new ways to make “radio history” by transmitting something that had never been heard before—weddings, broadcasts at sea, in the air, even under the water. In many cases such broadcasts served no purpose but to entertain and fascinate.

Using Weak Signals Software to Reach for the Sky
By Robert Gulley AK3Q

Many have no doubt heard of renowned physicist Joe Taylor K1JT, or at least JT65 or JT9 software. But weak signal mode software has progressed leaps and bounds since the introduction of these modes only a few short years ago, thanks in part to some great contributions from people around the world. The WSJT-X suite of software represents the outgrowth of these modes, and its latest incarnation, v. 1.70, has added even greater capabilities.

FCC Rewrites some Rules for CB/FRS/GMRS/MURS and Amateur Radio

Field Day 2017 with Ian Kahn, KM4IK – ETH071

Everything Ham Radio Podcast Logo - Field DayThe biggest hamfest is over, but the biggest ham radio on the air event is quickly approaching! Yes I am talking about Field Day 2017! Back in episode 67, I had Ian on and we talked about PSK31. During that interview he mentioned that he was the Field Day Chair for his radio club, the North Fulton Amateur Radio League, so I asked him to come back and talk to us about Field Day.

We had a great conversation about what Field Day is, some general information about it, what its like to be the Field Day Chairperson and be in charge of planning the event for your club and wrap it up with things that his club does during Field Day and what goes on afterwards.

Check out the show notes of this episode for more information about things that we talk about, links that we mention and probably some that we didn’t. The show notes can be found at:

There’s summat on the air now..but be quick

Recently I attempted a SOTA activation of Skiddaw G/LD-004. It is an easily accessible summit and a really good MTB route (called Back ‘o’ Skiddaw – although I’m not sure there is a link between the lake district and pirates but we’ll run with it). I’ve ridden it before but it has been a few years and the 17.5m route is straightforward and involves 2 out of the 4 lakeland MTB activities, these are of course:

  1. Riding – Sounds trivial but read on
  2. Pushing – Right its too steep / rocky / muddy. Get off and push the thing (generally up).
  3. Humping – Stage 3 is extreme. You have to carry your bike. It is very heavy after a few meters
  4.  Throwing – This is the last resort and usually used in the summer when vegetation is everywhere. Pick up your bike and throw it on the bracken. Step into the flattened area. Pick up and repeat.

As I said the route is straightforward. The kit is standard….

  1. FT817nd
  2. LiPo – 3S 11.1v 2200mAh
  3. SOTAbeams SB270 (no longer available but a great antenna)
  4. VX-8GR APRS handheld
  5. Fishing pole
  6. End fed half wave antenna and ilertuner
  7. Palm paddle key
  8. 7m fishing pole

So imagine the scene. Dropped son off at cub camp and parked up. the sun is shining and the breeze is gentle. A good spring day. No need to check the high level weather forecast as you can see the summit. Assume its a bit colder and windier up top so pack a lightweight fleece.

Ride off. Enjoy the view. Here are a few photo’s

Nobody this way

Or that way…excellent

 

 

 

 

 

 

 

Windy, cold and rocky. makes riding fun (ish)

 

I kept my helmet on to keep the heat in

Whilst on stage 2 (pushing) up seat how (a lower summit and not a SOTA one) a fell runner was coming down with full kit on. To the untrained eye this might sound reasonable but as this is Cumbria it is rare to see a fell runner (because they are very quick generally, blink and they’ve gone…into the mist) and its even rarer to see one wearing a jacket. I was concerned. Sure enough the wind got stronger and stronger. Even though I was on the windward face I was shielded or in some kind of wind flow niceness. It didn’t last. Over the top of the ridge and it was howling and cold. Quick up the top and find a windless spot on the leeward side of the summit.

Skiddaw is a loose rocky summit that is old, as are all the lakeland summits and valleys for that matter but thats a whole new post. The summit might have been in a wind tunnel. 40+mph and around 3c. Not good when you’re in shorts. So on with the spare clothes and set up. No chance of HF today and VHF was going to be a quick one. I tried 2m USB but couldn’t keep the antenna straight so switched to FM and added more rocks to the support. No joy. I had to drop it to ground level and made do with the few contacts I made. Not what I planned at all.

There will be many morals to take from this experience. I like to focus on the positives and ignore the negatives, it helps block out the cold in this instance. So the main points…..

2 hours up……..10 minutes down…….great down hill section weaving around the many walkers who on the whole were much better behaved than they have been in the past. Just don’t touch the brake rotors for a while and keep them spinning. 😉

Next summit will be…….TBC

Pursue Radio Operating Goals

Operating goals or awards are a fun way to keep focused on accomplishing something via ham radio. Really, it’s a specific reason to get on the air and make radio contacts. I am not big on idle chit chat via the radio (“the weather here is 65 deg and raining”) so having a reason to make contacts helps me get on the air. I’ve tended to pursue awards in a serial manner…once I hit some level of accomplishment, I usually declare victory and move on to something else.

Way back in the wayback machine, the first award I pursued was Worked All States (WAS). It does take some effort but I was pretty active on the HF bands at the time, so many of the states just showed up in my log. But to really drive it home, I kept track of which states I still needed and actively looked for opportunities to work them.

Next up was Worked All Continents (WAC), which obviously requires working some DX. But then I decided that if I was going to have any DX cred at all, I needed to get DX Century Club (DXCC). This turned out to be a bit of a challenge with my modest station (100 watts and a dipole) but I found that working DX contests to be very helpful. The big hassle was collecting the QSL cards and getting them checked by the ARRL (back before the Logbook of the World days). Once I checked the box on DXCC at just over 100 countries, I was satisfied and went on to other things. Serious DXers chase all available countries/entities to get Honor Roll and other bragging rights.

The VHF and higher bands have always been a passion for me, so I pursued the VHF/UHF Century Club (VUCC) awards. First, it was 6 meter VUCC, the easiest one to get. A really good run during the ARRL June VHF contest can produce the 100 grids you need for the award in one weekend. For me, it took a few more contests than that after factoring in the fallout that occurs when trying to get confirmation QSLs. The 10 GHz VUCC only requires 5 grids which turned out to be not too difficult. My VHF collaborator at the time, Doug W0AH (now W4LY) and I took turns operating from Pikes Peak while the other guy went out and activated the required 5 grids. It helps to have a big honkin’ mountain nearby to use for 10 GHz operating. About this time, I got into working the LEO satellites and worked the required 100 grids for satellite VUCC. I don’t have very many grids confirmed on 2 meters, so that one is still calling to me.

Recently, I spent some effort going for the CQ WPX Award (worked prefixes award). This is an intriguing award structure because every new callsign prefix counts as a new one. For the basic mixed-mode award, you need to work at least 400 different callsign prefixes. I found this format to be a lot of fun because “everyone is DX” so to speak, but DX prefixes are also very valuable. The same approach is used for the WPX contests, which naturally brings out stations with less common callsign prefixes. A big motivator for me was when the ARRL announced Logbook of the World (LoTW) support for the CQ WPX awards. I mean, there was no way I was going to collect 400 QSL cards to submit for this award, but using LoTW made this very efficient. More on that story here: CQ WPX, LoTW and the End of QSL Cards.

Summits On The Air

Lately, I’ve been active in the Summits On The Air (SOTA) program, both activating and chasing summits. This is a natural fit for me as I’ve enjoyed mountaintop operating in various forms, mostly on VHF and UHF. (See my SOTA blog postings.) The SOTA program has a wide variety of awards, supported by a very powerful database used to record SOTA radio contacts and keep track of the scores. It is not really a competition but there is friendly rivalry between SOTA enthusiasts as they monitor each other’s posted scores.

I’ve been using VHF (and UHF) exclusively for SOTA and managed to qualify for the Shack Sloth Award using just those bands. (Shack Sloth is achieved with 1000 chaser points.) Shack Sloth is a bit of a misnomer for me as many of my SOTA chasing contacts were done while hiking, mobile or portable (not sitting at home in a shack). The Mountain Goat Award is taking a bit longer because I have to drag myself up enough summits to reach 1000 points as a summit activator.

Here’s the current scores for the Colorado (W0C) SOTA activators:
At the top of the list, we find Carey KX0R totally killing it with 2808 points. These folks have all reached the coveted Mountain Goat status: KX0R, K0MOS, K0JQZ, W0CCA, KC0YQF, W0CP, KC5CW.  I am further down the list, tied with AD0KE at 302 points. Now, remember this is not a competition 🙂 Honestly, I wish I were further along the path to Mountain Goat but I’ve decided to keep at it and enjoy the journey. Walt W0CP recently gave me some excellent advice: just keep making progress.

Other Goals

You may not find the awards and goals I’ve mentioned to be very interesting, but there are many other options. In 2016, the ARRL sponsored the National Parks On The Air (NPOTA) program, which created a lot of interest and activity. I did just three activations for NPOTA but many people really got into it.

You might also set your own personal goal, not associated with any award. I know one ham that decided his goal was to make a ham radio contact every day of the entire year. This sounds simple but if you have a full-time job and other responsibilities, it takes some persistence to make this happen. Perhaps you are public service oriented; you might set a goal for the number of ARES events you support this year. I challenge you to think about what it is you are trying to do with ham radio and set a goal that is consistent with that.

Those are my thoughts, what do you think?

CLE 219 Results


As originally feared, MF conditions took a nasty beating this weekend during the monthly CLE .

It's really amazing how closely synced to terrible conditions the CLE's have become ... perhaps we need to offset our monthly activity by staging the next one in two weeks to see if we break out of sync with the Sun's regular 27-day rotation of coronal hole streaming.

Friday night was the best, much better than most other regions in North America from what I could tell as the geomagnetic storm had not yet struck ... but most others suffered from severe thunderstorm noise further to the south and east of BC.

Once the geomagnetic storm was underway, the DST quickly tanked and both Saturday and Sunday nights saw a shroud of absorption thrown over the NDB band, at times making me wonder if I even had an antenna connected to the receiver. I haven't seen such poor conditions on MF in several years.
