160 M ARRL contest

Finally again qrv on 160M. Last 2 (winter-)seasons I was not planning correctly with my neighbour who is using the land for his sheep feeding on the grass.

Only 3 x 20M radials, but my grassland is wet wet wet. Everything was working, SWR just above 1:1 on 1810 kHz. No beverage in USA direction, no time for that before darkness fell.

I worked on Saturday-night & Sunday morning. Signals were very very light and qsb. Managed 16 qso’s, Eastcoast only. I think Alabama was DX. Still zone 5.

Outside the contest I worked 2 new challenges on 160M: ZA1WW and S01WS. Nice come-back!

2 drone movies PI4GN UHF-site in contest May 2017

I have a drone with 4K camera. Last weekend made some footage of the contest-site of PI4GN. Not to long, contest had to go on.
And when transmissions are going I do not fly the drone. You never know where it will end with so much energy nearby….


LFD in my optical fiber terminal

End of December I switched my tv-telephone-internet to the new optical fiber network.
I was very happy with this switch because I could terminate my satellite dish tv and improve my internet speed from 2 Mbit to 200 Mbit.
The fiber is terminated with a so called DKT from COMEGA. This unit splits the signal into 3 parts: tv (DVB-C), telephone and Internet.

But after a few weeks I found out that on certain bands (especially 20 M) in certain directions (especially 330 – 030 degrees) my glasfiberterminal ‘crashed’. The RF-signal for DVB died, while internet and telephone were still running. Full reset (power down/up) did reset the unit.
But I remember one day that after transmitting (North) the whole unit stopped working and had to be physically replaced …..

My provider does know about the problem and is testing a solution but up till now (3 months later) no improvement.
I tried to isolate the unit for RF like shielding with grounded silverpaper.

 

 

But no real improvement, especially on 20M things go bad. 100 Watt with the UB-50 beaming North is enough to kill the DKT. The tower is 9 meter from the DKT, the antenne is 10 meter up.

So I entered a complaint at the Dutch ‘supervisor’ Agentschap telecom.
They requested a list of measurement data in order to analyze the situation.
Today I did some measurements.

I’m done with my SteppIR

December was very quiet for DX’ing. We had a lot of gales up to 10 Bft so I lowered my antennes.
The 80M vertical (a flexpole) fell over but didn’t break. The pressure on the elements is so much that they go back inside the one below (hopefully this is clear when you know how the system works).

160M I didn’t even bother about to setup. The sun is very active and condx on 160M are very bad. So next year.

But now the DX is coming: EP6T. So I tuned my SteppIR to the band and measured SWR: it was off.
Calibrated and SWR was OK. Made qso. Changed band. SWR was off again. Calibrated. SWR ok.
I measured all the connections (Controller <> elements): all 20 ohm = OK.
I changed every single element (create, modify): all elements are moving in&out.
Reset to factory defaults: no improvement.

This SteppIR makes me crazy!

So for sale:

4 ele SteppIR 20M>6M with extra 6M option, new shoes, 20m controller cable, controller SDA 100, connection cable Kenwood. € 500 pickup price.

CQWW SSB

Entered the contest in Single Operator 15M high power (400 W) Assisted. After 500 qso’s and 21 hours ‘on’ it was enough.

One zones was not on (39) and some were very thin populated (12, 19, 29: only one qso). Most times I was on S&P-mode but I did give cq’s a few but no real runs were made out of those actions. Still wonder how to get passed 500 qso’s running S&P only.
And still wonder why running cq is getting so less answers when runninjg 400W in a 4 ele SteppIR.
It was difficult to find a free spot in the band but my power must be enough to be heard. But not an interesting zone I guess.

In the middle of the contest I saw a spot of YB9Y on 80m cw (Saterday around 15 gmt). I heard them calling a managed a qso!

Today we are having extreme weather, storm 9-10 Bft in my part of the country. The gusts are most dangerous.
This morning I wanted to lower my 80M inverted-L but it was to late: broken in the middle. Glasfiber is not as flexible as I thought.

Antenne problem, rotor problem, winch problem

A problem never comes alone….

Yesterday while sitting in the garden I saw my antenne turning around.
Apparently on the wind direction? A dangerous situation, because if it should turn more than 360 degrees I would loose my tx-cables.

After studying its moves I decided to lower the mast and check.

That was a big problem, the winch was nearly stuck. But the mast had to go down, some more power on the winch….

All the bolts on the pipe/rotor connection were not tight anymore. How come? But easy to fix.

Then up again, the winch was rotating very difficult and got stuck. The mast at 45 degrees.
Called Arjan Wind and he was able to come the next day. We Imagechanged the winch with a bigger one. Turned out that the old one was really broken, the main axis was bent. Guess a 40 kg SteppIR was to much to lift after all these years (about 10 years old winch).

But after 24h the system was up and running again.

Topband season is ending

Days are getting shorter on this side of the globe, dx-window for 80&160 getting really short now. So time to dismantle the verticals and beverages. The farmer needs the ground in a short while.

This season was pretty good ending with a total of 124 countries worked on 160M (last year 97) and 177 on 80M. That is the total since I started on 80&160, not only this TB-season, to be clear.

On 160M starting Jan 1st, 2013 worked KL, KH6, 9M4SLL (1S), T4, FS, HK, VP2M, 6Y and FO/C on 160M. Some of them with outstanding signals near SR or SS.
Still struggling with the beverages though, I don’t feel they add much to my reception quality. Most times the noise is down but signals more down. The reverse beverage from DX_engineering is not performing well, no difference up or downstream.
I heard KL7KY stronger on the vertical than on the beverage! In order to work more I have to hear more, tx is OK with 750 Watt into inverted-L with 50% efficiency.

Still having problems with my SteppIR. After some band-changes the SWR is rising sharply. I now use high voltage (33V) on the system but no improvement. The repair of the elements didn’t make any improvement. I checked all copper wires but they are OK. So now I’m out of ideas what’s wrong with. The system is 8 years old (bought 2nd hand, but then it was OK).
Thinking about selling the SteppIR and the retrofit kit for 30/40 (still lying around) and buying the UB50: smaller 3 elements, lighter, 30/40M integrated in a clever way. But a lot of money.
Something to think about in the summer.
