Comments:

Better conditions than expected. Especially on 80m the first night.

Thunderstorms prevented much operating on Sat evening.

Surprised to find 10m open on Sunday morning. My best multiplier total ever.

QTCs are something you just have to deal with. Most annoying when you find a mult on 10m and they keep taking QTCs. Instead of working 100/hour, they end up working about 40/hour rate.

Spent a lot of time outside enjoying the Summer weather or inside watching the Olympics.

Comments:

Had the best of intentions to make a serious mixed mode effort. Spent a sleepless night on Thursday in the Newark airport. Tried to catch up on sleep and woke up 15 minutes before the contest.

Started out on CW. When I switched to SSB, I discovered that Writelog was not forwarding the mic audio to the radio. I could record messages and play them, but no live audio. Probably a configuration error, but my bad for not checking things out in advance. After 20 wasted mins, decided to go CW only.

Conditions were good enough to be entertaining, but certainly not great. I spent a lot of time practicing with dual CQ. It is amazing how well it can work, and how easily you can get messed up and sound like a lid.

Enjoyed watching the online scoreboard and chasing AA3B and K1MK. Especially after I started taking breaks. It was fun to see if I could make progress on catching them.

Surprised to work some EU HQ stations on 160. They were weak here, but seemed to be hearing very well.

Finally nearing midnight, decided I had enough and packed it in.

Always fun to hand out the WRTC memories by using WR1TC. People really seem to copy this call on the first try!

Battle of the Hams

One of the best descriptions of amateur radio contesting appeared in Sports Illustrated back in 1958. It was written by Bill Leonard W2SKE (SK) and takes the reader through a 48 hour DX contest. A great way for non-hams to understand the craziness, passion, and magic of staying on the radio for a full weekend chasing contacts from around the world.

Excuses:
– My son was visiting for the weekend
– Beautiful weather outside
– Monaco F1 race, Indy 500

Conditions were entertaining. Great activity from Europe as always. Conditions Sunday morning were better than Sat.

Surprised how easy it was to work Europe on 80m. Must have been low QRN on their end.

Great fun watching the online scoreboard and chasing NR3X and NK7U. Caused me to operate many more hours than I would have without the extra motivation.

40m beam has SWR problem. 15m antenna not rotating. Seems to be something broken every time I get on the air.

How much is using Assistance worth?

There is always a curiosity about how much of an advantage does one gain from operating Single Operator Assisted (with access to the DX Cluster spots) vs traditional Single Operator.

With the intense single op competition here in New England for CQ WW CW, we have some data points to help answer that question. K1DG and K5ZD have operated from the same stations over this period. K0DQ has been from two stations, but with similar results.  All three are hard core operators who make the most of their time on the air.  Given the scores are fairly similar over the years, we can assume the difference for the 3 single operator assisted entries by K5ZD is mostly due to DX spotting assistance.

In a post on cq-contest (May 26, 2016) where he presented this data, Doug KR2Q wrote:

…using assistance or being unlimited gets you more mults and hence a bigger score (relatively speaking).

All of the top guys (such as these three) use SO2R.  If you are SO2R and using your 2nd radio to find new Q’s (hopefully, new mults), when you tune using the not-assisted method you are “blind.”  You don’t know what your might find (which is fun).

When you are SO2R and use assistance on your second radio, you are not tuning “blind.”

You know just where to go to grab new mults.  So it would seem obvious that using assistance when SO2R would a higher mult and assuming you don’t neglect running on radio 1, a higher score.

I started doing SOA in CQ WW to have more fun and work more interesting DX.  I was tired of working 40+ hours and then learning there were many expeditions and rare stations that made several thousand QSOs that I never heard all weekend.  Having the cluster spots helped me find these stations as well as lots of other weak ones.  It is pretty cool to nearly achieve 5BDXCC in a weekend.

One of the great things about radio contesting is that we each get to determine our own goals and levels of competition.  I have enjoyed doing contests solo, but it is also a lot of fun to have the additional challenge of managing the non-stop stream of DX spots that the DX Cluster and RBN provide.

Convergence and Change – An Editorial

This originally appeared in the May 2016 issue of CQ Magazine along side the 2015 CQ WW CW results. It represents my opinion and not that of CQ Magazine or the CQ WW DX Contest Committee.

Many years ago the best DX and contest operators were hunters. They studied the bands, knew when the rare DX was most likely to be on, and could even recognize the sound of that rare station needed for a multiplier. As technology improved, stations got better and more capable. Personal computers entered our shack to help with logging and sending CW. With better equipment and more stations on the air, the game started to change from hunting to running.

In the mid 1980’s, Dick Newell AK1A invented PacketCluster® software that allowed operators to enter the call and frequency of a DX station – a “DX spot” – and have it announced to everyone connected to the VHF packet network. Suddenly we could have hundreds of others telling us where the DX was hiding. After some controversy, the CQ WW added the Assisted category in 1989 to place those using this new tool into a separate category.

In early 2008 a new innovation appeared. Alex Shovkoplyas VE3NEA introduced his CW Skimmer software. CW Skimmer is a multi-channel CW decoder that copies all of the callsigns in the receiver passband and displays them on the screen. It had amazing CW copying ability – especially when Software Defined Radios provided the ability to capture a full 96 KHz of each amateur radio band. It suddenly became possible to simultaneously copy and announce every station calling CQ on CW across all 6 amateur radio bands along with their signal strength!

Soon after, PY1NB and N4ZR began building out the Reverse Beacon Network (RBN). The RBN collected data from CW Skimmers around the world, made it available to DX Cluster nodes, and stored it in an archive. This concept was quickly adopted by contesters because it provided immediate knowledge of activity around the world. You could call one CQ and see your signal reported from every Skimmer where there was propagation. The archive was a rich resource for propagation and antenna evaluation.

This convergence of personal computers, Internet access, DX clusters, and CW Skimmer have changed the nature of CW contesting. Even the smallest station can now call CQ and be noticed. The top multi-operator stations have developed the ability to interlock multiple stations on a band so they can chase these Skimmer spotted stations in between CQs on their run frequency. Many single ops talk about the fun of doing all of their operating just by working stations found when clicking on DX spots.

Like it or not, the CQ WW CW (and contesting in general) has certainly been impacted by this convergence. Having so much information has helped more people have more fun – generating even more activity and QSOs for everyone. It has also made it more difficult to police the line between the single operator working alone and those who are using the assistance of DX spotting. Anyone who has received a ham radio license in the last 25 years doesn’t know amateur radio DXing without the DX Cluster.

We have to remember that contesting is ultimately a game played using the ionosphere and our ability to hear far away signals with our own ears. Enjoy the tools, but never forget that our real purpose is to build and test our skills as radio operators. Given our history of technology innovation, when does it make sense to accept convergence and recombine the single operator categories – giving everyone access to spotting information?

Wow! Sure didn’t expect conditions to be this good. Every band was great during the times I was on.

Only a part time effort, but that made it even more fun. Mostly chased countries and tried to run when I could find a frequency.

Personal best hour from the USA with 229 on Sat morning on 20m. SH5 says best 60 mins was 230 QSOs. Lots of other good hours. When I could find a frequency where I could hear.

Splatter was bad, but I did say something to a few of the worst and they seemed to be able to clean it up. You don’t know if you don’t ask.

Was fun being Assisted so I could chase countries. Also had the online scoreboard up so I could track some of the other guys. Fun to try to catch the next score on the list.

My goal was 1000 QSOs, but conditions and rates were so good, I couldn’t stop.

Most amazing opening was Sat evening on 15m into Japan. Signals were really loud and I was even able to run JA for 45 minutes.

I went single radio for this one. Something is going on in my shack and I get terrible RF feedback in the headphones when using the YCCC SO2R box. It was clean when I plugged the headphones into the radio. With the DX Cluster, I didn’t really need the second radio.

23 stations worked on 6 bands! Its nice when 10m and 160m are both open.

Elecraft K3 Settings

I have two Elecraft K3 radios that I use for SO2R.  I am creating this page to record all of the various settings in the radios so I can find them if needed.

N1EU recommended settings for best pileup performance:

AGC SLP 000  (maximum slope, instead of horizontal)

AGC THR 014  (so AGC doesn’t kick in until signals are very strong)

AGC DCY Soft

AGC PLS nor

AF Gain is adjusted so the loudest signals are tolerably loud (around 9PM) and RF Gain increased until weakest signals are readable (around 3PM).

 

Bob, N6TV, recommends the following K3 settings:

First set CONFIG:TECH MD ON to un-hide some AGC settings. Set TECH MD OFF when finished, to eliminate useless options from appearing in the SubRx display choices (PLL1, AFV, dBV, etc.)

AF GAIN LO — Cuts audio hiss. May not work with all headphones. OK on Heil.

AF LIM 20 — Only takes affect when AGC is OFF (rarely used)

AGC DCY Soft — Reduces AGC-induced IMD, recommended for pileups

AGC HLD 0.05 — Slow AGC hold time (50 ms). Reduces AGC-induced IMD, recommended for pileups. Works with AGC-S only.

AGC PLS NOR — Loud static pulses do not pump AGC.

AGC SLP 010 — A pretty “flat” AGC response curve. I may move this lower since pileups of loud guys can blend together, but I like this setting because it saves my ears.

AGC THR 010 — AGC kicks in at about S-8. Signals lower than THR behave as they would with AGC OFF ( +1 dB of RF = +1 dB of audio)

AGC -F 120 — Factory default fast AGC decay rate (recovery time). Higher = faster. Faster can be bad.

AGC -S 20 — Factory default slow AGC decay rate (recovery time). Higher = faster. Faster can be bad.

RF GAIN at 3 O’Clock or less on noisy bands

AF GAIN never higher than 3 O’Clock

AFX OFF

NR OFF

NB OFF

RIT OFF

XIT OFF

FL1 to FL5 BW set to match labeled filter bandwidth exactly, not wider or narrower.

Use AGC-F for CW.

Use AGC-S for SSB.

CW Pitch 500 (or to taste)

IF shift centered (on CW)

500 Hz InRad 8-pole filter on CW

2.8 kHz 8-pole filter on SSB (1.8 8-pole when bands crowded, must move IF SHIFT lower for pleasing audio)

Use XFIL button to toggle between filters and reset the IF shift, rather than NOR (hold) button

PREamp ON for 15m and up, OFF for other bands

 

My current settings for other items:

AF GAIN Low

AF LIM nor 030

EXT ALC Off t -4.0

LIN OUT nor 020

RS323 38400 b

Comments:

My father-in-law passed away last week and the memorial service was on Saturday.
The service and visiting with family was wonderful. That eliminated Saturday
from operating.

Really enjoyed my few hours on the air. Nothing like getting to 15 meters for
the first time on Sunday morning. The pileup was intense! Made me truly
realize how valuable it is to tune off the spot frequency. Those were the guys
that got through fastest.

Best 60 mins was 210 QSOs.

DX contests are really fun when you are not trying to win anything. You can
come and go as you like. Conditions were surprisingly good during the times I
was on. 10m was spotty on Sunday, but there were some loud Europeans. Worked
JA on 80-15.

Worked 19 stations on 6 bands: 6Y1D 8P5A 9A1A CR3W CU4DX KP2M OL7M OM2VL P40XM
PJ2T PJ4X PJ6A SN7Q TI5W TO7A V26M VP2MWA YL2SM ZF1A

Thanks to all the Europeans that helped fill my log.

40m antenna had high SWR. It seemed to get out, but I wasn’t hearing very
well.

160m antenna toward Europe was broken. Missed some mults because of that.

Couldn’t switch the 80m 4 square on Friday night.

Station is falling apart from old age. Time to do some maintenance this
summer.

Rope for Wire Antennas

There was an interesting exchange of views on the topic of ropes for wire antennas on the Yankee Clipper Contest Club email reflector this month. I wanted to capture some of the discussion for later reference.

On Feb 5, 2016, at 1:02 PM, Lars KE1J asked:

My dipoles came down today due to the heavy wet snow. Clearly the rope I used was not strong enough. Any suggestions for a good rope that can hold some wire antennas?

de K1LI:

The MastrAnt rope that guyed the towers at WRTC2014 was spectacular.

I’d think you’d worry more about trees pulling each other down than you would about this rope breaking!

And, they were a corporate sponsor of WRTC2014, which puts them high on my list of “go to” vendors.

Widely available at US ham equipment distributors, like DXEngineering.

You can see their products at:    mastrant.com/en

de K1WCC:

There is a store in New Bedford, R&W Rope Works, that sells all kinds of rope. They opened their warehouse a few years ago to sell surplus rope, I went there, they had large amounts of all kinds of marine rope. I bought some 3/16″ dia. braided dacron, about 500 ft. and it’s tough and strong, designed for sunlight and abrasion resistance. I think they have a store there now, or, order online. My dipoles are still up, (just worked St. Helena with one of them) despite being coated with ice and snow right now.

I’m more concerned about wire strength.

Also, Davis RF is now in the rope business.

de N2GZ:

I have been using Dacron rope sourced from davisrf.com. I bought a lot of it (savings in bulk) and im going through it slower than i thought I would.

I employ a technique that lends itself to rapid rapiers:

Using a heavy (5/16 or greater) rope, I install a loop in each tree that will support the ends of my antenna. The loop is tossed over the support branch and is joned at a welded stainless ring of approximately  1 inch ID,

1/4 inch wire diameter. Mcmaster part 3769T74 or similar. a smaller ring would probably be fine. A swivel sheave could probably used here with added expense.

I then use  a smaller rope, usually 3/16 diameter to support the antenna.

Shorter and lighter antennas require less tension to deploy, so a smaller rope could be fine here for shorter dipoles.  This rope is passed through the welded stainless ring (or sheave).

The antenna is raised first by moving the steel ring to the top of the tree, and securing in place by tying off the loop of heavier rope at the base of the tree. Then the smaller antenna support cord is tensioned to position the antenna as desired.  When deployed this way, there seems to be far less abrasion on the rope that passes over the tree branches, and the the rope that is likely to break is the one supporting the antenna. Should it fail, simply lower the ring/sheave with the loop of heavy rope and replace pull up a new antenna. Far easier to do rapidly, no need to get the cannon/slingshot out and no amount of luck is needed to get the rope placed as you had it before.

Sometimes it is desirable to install a fuse (smaller diameter rope) between the antenna and antenna support rope. so that it breaks in a specifiedspot, allowing your rope to be reusable without intermittent knots.

Greg, N2GZ

de W1HIS:

Yes.  _Wire_ rope beats any organic (natural or synthetic) fiber rope; however, wire rope must be broken up by insulators, and insulators don’t pass through pulleyvery well.

The best organic fiber is polyester.  No other organic fiber resists sunlight well.  Only one other organic fiber, namely Kevlar, creeps less than polyester.  (By creeping, I mean extending under sustained load.)  However:

  • Kevlar does not resist sunlight well, so it requires a braided polyester jacket.
  • Kevlar absorbs up to 7% of its weight in water!  It is a lousy dielectric.
  • Kevlar does not resist abrasion as well as polyester.  Although a braided polyester jacket would protect Kevlar fibers from external, or “surface” abrasion, Kevlar’s resistance to “internal” abrasion or fatigue due to repeated flexing is poor!
  • Kevlar is quite brittle.  A shock breaks it easily.  A falling tree branch would be much more likely to snap a Kevlar rope, than a polyester rope.

Last but not least, black Dacron/polyester double-braid rope is relatively inexpensive.

IMO, nothing matches black-jacketed Dacron/polyester double-braid rope.  The braided jacket protects the unpigmented, _straight_ (not twisted), fibers that provide the tensile strength of the rope.  The lack of twist is important because a twisted rope untwisted and extends under a sustained load.

You should buy rope whose rated (breaking) strength is ten times the sustained load (tension) it must endure.  I control the tension in a rope by hanging a lead weight on the free ends of the rope, which is fastened at one end and passes through a block to the hanging weight at its opposite end.

You should reduce wear on ropes by using pulleys (a.k.a. “blocks”) with large diameter sheaves (wheels).  After years of replacing rope worn out by 2”, 3”, and 4″-diameter sheaves.  I now use only 5” and 6” diameter sheaves.

Thus, I have gotten years of service from ropes, despite hurricanes, nor’easters, ice storms, and tree branches falling on my antenna and its supporting ropes.

For several years I have bought black Dacron/polyester double-braid rope from <http://www.synthetictextilesinc.com/supportham.html>.

-Chuck W1HIS

Note:

(1) Nylon does not resist sunlight well.

(2) Under tension, a Nylon rope grows longer, and longer, and longer.

de W1EQO:

Using an insulator between a nylon rope and the wire helps a lot.

The problem is we hams mostly use a class of wire antennas known as “standing wave” antennas (dipoles, verticals, yagis) vs another bunch called “traveling wave” antennas (loops, folded dipoles, resistor in the center folded dipoles, etc).

Standing wave antennas are characterized by an end (or ends), beyond which current does not flow. This is commonly called the “end effect.”

The end effect determines the feed point impedance of a standing wave antenna.

So, attaching a resistive chunk of nylon rope to the end of a dipole changes the feed impedance or VSWR. Also it is an absorbing extension to the wire, which I would expect, reduces the amount of radiated RF. Possibly even worse, the resistive value changes with weather and time.

Placing an insulator between the wire & rope mitigates this problem

Jim, W1EQO

de KI1H:

After the flurry of emails on the subject of rope last week and seeing my beams bowing to the weight of the heavy snow, I deciding to do a little research.

As was mentioned, Kevlar is resistant to stretch but not UV stabilized unless jacketed.

I did find a source for a material that stretches less than 1% at 30% load ( at 1/8″ that is 750 lbs load).

Look at the link below.

http://www.samsonrope.com/Pages/Product.aspx?ProductID=872

I called the manufacturer and it’s non-conductive.
