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.

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.

  1. Hello Bert,

    Those are fantastic cards. I like the arrangement and display very much. You've done a unique job on them . I'd be proud to get any of those in the mail, photo's, web etc. Great Job !!

    1. Hello John, First I had to figure out, how I could give info on my the power adjustment of the set and the attenuator. Yes, this card is unique. Thank you. 73, Bert

  2. Good afternoon Bert, as John has just said these cards are great and they do show all the info and plus some nice added extras. It' neat the way the card informs you about power, miles per watt and the dB used in the contact as well to get to the QRPp power level. Very well designed Bert!

    1. Hello Mike, With this card the operator of the receiving station can show to other HAMs, that he made a more than 1000 MPW QSO. Therefor it is important, that all info for 1000 MPW is on the card. Same HAM wrote back that they would apply for the 1000 MPW Award. hi. 73, Bert

  3. Hallo Bert, een hoop werk om dit allemaal in te vullen. Nu maak je met QRP(pp) natuurlijk ook geen honderden contacten dus aantallen QSL zal ook wel meevallen. In iedergeval geef je een hoop meer info dan de gemiddelde radioamateur. Vind het wel wat hebben. Een kwaliteits QSL zeg maar. 73, Bas

    1. Hello Bas, it's much work indeed. I am sending cards from the third batch of 1000 QSL cards for 1000 MPW. From September 2012 until this month I have send 200 QSL's for more than 1000 MPW QSO's.
      In a typical DX contest 50 to 70% of the QSO's is a more than 1000 MPW QSO. In the ARRL DX CW every QSO (160 in 2013) is good for 1000 MPW. 73, Bert
