UBA DX contest 2015

This weekend I participated in the UBA DX contest.
The conditions were not very good , but I still made 27 QSO's with S&P in CW.
I could make 1 QSO with less than 100 mW, 3 QSO's with 800 mW.
The rest of the QSO's was made with 3 or 4 watts.

Rigth at the start, I heard YT1A.
Vladans signal was very strong, so I reduced my power.
With the FT-817 set to 800 mW and with the "PA1B 40 dB step attenuator" set to 10 dB,
the power to the antenna is reduced to 80 mW.
With a distance of more than 900 miles, this results in more than 11000 Miles/Watt.
This was the only QSO with less than 100 mW in this contest.

After that I made QSO's with 800 mW to 4 watts.
The FT-817 here gives less than 5 watt with full power, after a serious mismatch.
This is less than 4 watts on 14 MHz or less than 3 watts on 21 and 28 MHz.

The ribbon of the Inverted V is not yet repaired.
As long as there is no wind, all is OK . See the post on the PACC 2015 Click.
But with a wind force of 6 on the scale of Beaufort , it was not always easy. hi.

Info on my 1000 Miles per Watt QSL card

Last week I wrote a small pile of 60 QSL cards. Almost all of the cards were for QSO's with more than 1000 Miles per Watt. The used power in the QSO's was 2.7 Watts down to 1.8 milliwatt.

While I was writing the cards, I took up the plan to take a photograph of one of the many "more than 1000 Miles per Watt QSL cards" that I was writing, just to show how I present the "1000 MPW info" on my a card.

Photo
Actually I was going to photograph the QSL card, that I would send to LZ6C for a QSO with 1.8 mW. For this QSO I calculated 559091 Miles per Watt.
But when I just looked on the camera, it turned out to be that I took a picture of an other card for a QSO with LZ6C, that was made with 36 mW. I can not take a new picture, since both cards are already on their way to the Radio Club Silpa. hi

Please click to see all the interesting details for 1000 Miles per Watt

1000 MPW info
At the top of the card I give the power catatgory:  QRP,  QRPp  or  QRPpp.
QRPpp is the (not official) term, that I use for a power of less than 100 mW. hi
The FT-817 can be adjusted to 5 W, 2.5 W, 1 W or 500 mW, so I encircle the used power.
Well, after a serious mismatch the power of my FT-817 is 360 mW when adjusted to 500 mW, so I write 360 mW above the FT-817.
Since I used the 10 dB attenuator, I encircled the value 10 dB in the attenuator.
The most important value is the power to the antenna. Here 36 milliwatts.
My locator is JO22na. The locator of LZ6C is KN13ot.
Using both the locators, I calculated the distance and the Miles per Watt, with the excellent (Click) N9SSA Distance and MPW Calculator.
The distance is 1006 Miles and 27955 Miles per Watt.

Thanks to the Radio Club Silpa with their Excellent Ears.

10 dB Attenuators

I made a presentation on 10 dB Attenuators.

Please let me know, what do you think of it?

I use a free version of Prezi that I could use for a month. In this time I made this presentation. Now I can not longer change the presentation.
