A permanent 30m solution? At least: I hope so.

The 30m band has always been my favorite. It supports DX all year round, all through the solar cycle and most hours of the day. I like that fluttery polar path sound of W6/W7 at my winter sunset. Or winter sunrise: a full hour of my best JA pileups time after time. I wish I had those in the contests. I once tried RTTY on 30m on a summer evening when the sun was indeed rising in the land named thereafter. They went nuts. Not many Belgians really CQ’ing on 10.1 MHz it seems…

I spend many weekends on the regular contest bands. But I also like to work some casual DX. So I try not to call CQ on the contest bands but revert to WARC. Especially 30m.

In 2004 I started with a 12+17+30m triband dipole on top of the tower. It brought me lots of DX pleasure for its size and simplicity. Too bad the trap got blown almost ten years ago.

The Toasted Trap

 

I removed this dipole and replaced it with a 40m rotary dipole. This antenna is so kick-ass good that 7 MHz is my best band, especially since the higher bands are worked with a yagi. So this antenna can never go.

After that I have been trying various things for 30m. It all works but never as good as the flat top dipole on top of the mast, even if it was trapped.

A delta loop.

A triband WARC wire dipole.

These are all antennas that work. Especially if you don’t have anything else. But they need to be put up when there is no contest and taken down when there is a contest. Because they eat up real estate, or use a pulley that is needed for 80/160 low band contesting etc.

I was looking for something that can be installed permanently without interfering with my contest setup. So I was looking at the OptiBeam (link) or DXAvenue (link) dual band dipole. Or upgrade / modify my OptiBeam 40m dipole to include 30m. This can easily be done but the major issue was hooking up the 30m parts to the 40m loading coil.

But in Spring there was this OptiBeam 30+40m dipole for sale on the second hand classifieds. The price was right so I did not hesitate and bought it. I went to pick it up and installed it this week.

I could keep the feed point assembly on the mast as it is the same size and length. That made installing it easy. Moreover I could use a friend’s scaffold which made the one man install job quite easy.

A new antenna for 30+40m. 30m is my favorite hangout for casual DX. And I lack a permanent antenna for it. I upgraded the existing 40m rotary dipole to a dual band dipole for 7 MHz and 10.1 MHz. It's both of the German OptiBeam brand. I bought it 2nd hand for a good price. I could leave the mast assembly and feed point as it has the same length and diameter. So it was a matter of changing entire tube and coil assemblies left and right. I just hope it won't mess up the 40m performance as that single band 40m model works like gangbusters in the contests. I just wrote a blog entry about this on www.on5zo.be. ____________________________________________________________ #hamradio #amateurradio #hamradioantennas #antennaporn #40mband #30mband #optibeam

Is it a permanent 30m solution? That is now under evaluation. I’m sure it’ll work on 30m and bring me DX pleasure. And work better than any of my 30m solutions. The big question is: will it have any negative influence on my 40m contest results? If so, I will probably revert to 40m monoband operation. Let’s hope not…

 

 

Another contest you say? Yes, another contest I say!

This time: WAE CW. Yes: Worked All Europe. But Europeans don’t work Europe. We work DX. Yes: DX. That means: far away. Which makes it hard. We like things hard. If it’s easy anyone could do it. Actually anyone can do it. But not everyone is crazy enough to do so.

From the archives:

For the record: WAE CW

WAE CW is a bit of a stinker. WAE CW is one of my favorite contests. There you go, once again I exhibit a bipolar disorder.

WAE CW is one of my favorite contests because:

  • It is CW.
  • It is only DX and some nice one.
  • QTC! QTC? Yes, QTC. If you like CW and unpredictable exchanges, this is it.

WAE CW is a bit of a stinker because:

  • It’s almost always hot with a chance of thunderstorms that more often than never come to life.
  • It is not a rate contest and there is a very big imbalance between DX (not much) and EU (a lot of).
  • It can get slow and boring at times. “Slow like WAE on Sunday” is an expression.

 

What’s up with QTC?

This year it was just too hot. Ridiculously hot. A heat wave ramped up on Thursday with outside temperatures of 37°C and more. I knew this would be a problem in the shack. It would make for some very uncomfortable hours. I even contemplated not playing at all. In the end I decided to settle for a low key casual participation. After the contest I can say that the shack’s temperature was always over 30°C peaking over 32°C on Sunday. That’s inside, where I operate.

 

Another reason why I wasn’t tempted: N1MMLogger. The QTC part is the programmers’ nightmare and I suspected a few bugs this year too. I knew I had to test in advance but I just couldn’t get myself to do that. Also: I don’t like the dedicated QTC window that got introduced a few years ago. Under pressure of the RTTY crowd? Clearly mouse driven operating. YUK. I was very fond of the classic interface using the Entry Window to log QTC. No mouse needed! Never a problem. A few days before the contest I saw a few mails passing from the German contest reflector: QTC logging problems. There you go. I did a quick test of the latest update when I booted the computer late Friday evening. It seemed to work. But you never know…

I knew that I was making a tactical mistake by starting late and sleep the night from Friday to Saturday but I just couldn’t be bothered. First QSO at 0540 utc on 7001.85. Pretty low in the band. That’s 7 MHz real estate reserved for the big gun hotshot contest folks. And me. First reply: NO6T with that distinctive fluttery sound of a more polar propagation path. California Über Alles! Next up: W9RE and let’s shake the tree with a batch of QTC – success! The logger worked and I still could copy CW. The run didn’t last long. After such a late start the band closed for DX so I tried 20m to the east. That kinda worked too: a lot of UA9, a bunch of JA, a VK and I QSY’ed for KL7SB with QTC to boot. I got bored around 0700 utc and took a loooong break. I even took a beauty sleep after lunch. Unplanned and it was longer than it should have been.

The rest of the day (late afternoon, evening and early night) was spent on 20m and 40m. Running, begging for QTC and S&P for multipliers. I did a quick scan of the still unexplored 80m band and went to bed between 1AM and 4AM utc. The bed was empty: the XYL moved downstairs to sleep on the couch. It was much somewhat cooler in the living room than upstairs under the roof. I took a portable fan from the shack to the bedroom to create at least the illusion of a draft and exorcising the devilish heat. Nevertheless I slept deeply and even hit swiped the snooze button too often.

I was QRV for sunrise and found a noisy and deserted 3.5 MHz band. Not much to work and no replies to my CQ. A bit of a shame because the RBN showed my signal all over the globe. It wasn’t much better on 40. That is: the band was good but not many folks to work me. Break(fast). An hour later: back to 20 and 15. Fifteen was very quiet. No propagation. I squeezed out a signal and 10 QTC on 28 MHz: 4Z4AK. This weekend was Cycle 24 at its best in bringing out the worst: closed bands. Don’t care: another cool-down break and another excessive nap.

In the meantime a few threatening clouds tried to cramp my contest style:

 

It was very hot outside and relatively hotter in the shack. I got a peak of 32.5°C in the shack. I did my best to find the fun and I managed to find some consolation: I was working DX, chasing multipliers and getting QTC. I was not putting down a big score but it is what it is. Namely: HOT!

Shout out to my RX loops. They were invaluable for easy listening in diversity mode on 80+40m. And sometimes they were the difference between not making a contact or logging it in the end. The difference when switching between both directions was stunning this time.

Bottom line: WAE CW 2020 is done. Except for the heat is was a good one. No stress, lots of DX and of 1000 QTC logged. Hell yeah!

 

My 15th participation in this contest. One of my favorite contests. And I seem to do quite well: #12 in the top 100 of all times.

 

Statistics here:   http://scc.hamradio.si/euhf/statistics_top_100_all_time.php

I left the tower up after IARU. That’s three weeks. Make it easy on myself. Come Friday: 39°C heat, thunderstorms predicted – with possible heavy gusts exceeding 80 km/hr. Better safe than sorry so I lowered the tower on Friday in the scorching heat. Needless to say: no thunderstorm, no rain, no wind over my QTH.

Setting up again on Saturday, with low band wires and additional RX loop. Luckily my youngest son is becoming more handy and interested so I got a pair of little helping hands. His support is becoming more valuable instead of just symbolic.

Sweat all over the place while doing the antenna preparation. My T-shirt got soaked but everything got ready well in time and a shower washed away the sweat and body odor.

I had big fun chasing SJ2W for a z14 win. Check out his site ( http://www.sj2w.se/contest/ ) and IG account ( https://www.instagram.com/sm2wmv_sj2w/  ). Mike and I go way back since the good ol’ days of WWYC. We were young then, but we’re still kicking butt on the bands today!

BTW: Real time scores are a hit! Check it out: http://cqcontest.net/

You can’t beat the guys in S-E EU but at least we kept the Germans off. Of course: SJ2W is a BIG GUN station. He’s got a bunch of HIGH towers and more monobander yagis than my small tribander counts elements. His ‘in band antenna site’ on the side is even bigger than my station. But the race was a thrill and I enjoyed every moment of it!

It was very hot in the shack. Over 26°C before I switched on rigs and the amp. It got up to 30.1°C when running in the heat of the battle – pun intended.

Shout out to rookie OT5Z who did his first full time contest. Welcome to the scene and make yourself heard! Thanks for the ‘15’ multiplier!

 

The rate was fine and in the end I claim my biggest score ever: most QSO, most multipliers, highest score.

It does NOT get any better than this. Or does it?

 

Those who check out my IG account have seen this already but I want to gather the snippets in one post here. I’m learning to operate my employer’s laser cutting machine and instead of just cutting up and burning wood to charcoal, I try to end up with something useful – whatever this term may mean in this particular context…

Some of it is an enhancement of my previous experiment called ‘pimp your ham stuff’ (Sept. 2017).

I hope you like it as much as I did making it.

– … Since everyone voted ‘yes’ in the poll, here’s the last of my lasercut callsign creations. A set of letters cut out the same size as the laser ‘inversely etched’ board and spray painted in shiny gold. Then glued on with fast sticking glue. I made another one like this for someone else (kid’s room decoration) but with the shading done darker (i.e. higher laser power so the wood burns darker). The background is darker then making the golden letters stand out more. I liked this better than the one for me.

Ham Radio things with the laser cutter pt. III For years I have been using these wire antenna end insulators. Hand made with a hacksaw from a leftover piece of plexiglass plate. Recently I discovered these can be lasercut too. So I made the most of a broken cover of my small greenhouse (storm damage). 200x25mm, three 4mm holes for the wire ends, 7mm hole to hook it up. All lasered. These are used for dipoles, verticals and elevated radials. Easy to switch from CW to the occasional SSB length on 80m. Just slip wire through and fold back. It took a few tries to find the optimal travel speed and power setting for the laser but I got it nailed for 3mm thickness. ________________________________________________ #hamradio #amateurradio #radioaficionado #diyhamradio #homebrewantenna #wireantennas #lasercutting

I have been making use of Instagram for a while because it allows for fast publishing of BS and images.

Lately I haven’t got much to say that is blog worthy. After all these years you cannot keep on telling the same things about the same contests.

Here is a collection of things I posted about the 20m dipole on my portable field day mast made of tubular tower and a base with a winch mounted on it. I made a tapered aluminum 20m dipole which is a beauty but too heavy for my mast. This mast was designed to haul up some wire antennas for field day, not to carry heavy aluminum antennas. Let alone a rotator.

In the end I decided it was too risky to put this in the air even without any wind. I made up an ad-hoc wire dipole on two cheap lightweight fishing poles I have here for almost ten years. This worked just fine on a mechanical level and proved a winner RF-wise to fill the gap when the beam was to USA. It was oriented with the antenna lobes radiating to Japan and SW-EU.

The center assembly for the 20m dipole is ready: feed point and bracket to attach to the portable field day mast. Starting diameter is 40mm. A bit overkill for a 20m band element (~10m long) but the center isolator was made for this and I don’t have access to a lathe right now to turn it down. Adapt, improvise, overcome. Maybe I’ll use agressive tapering to get to a smaller diameter fast. I’ve never put anything this big in my /P mast. Only wires. I hope it’ll work. Build first, worry later! ________________________________________________ #hamradio #amateurradio #diyhamradio #hamradioantennas #antennaporn #dipoleantenna #homebrewantenna
