Using the lowest possible power in a contest QSO is not so difficult as it seems. In the CQ MM DX contest I was suprised by the excellent propagation, which made it possible to work with stations in South America and North America with just 1 W or 2.5 W.
2 Way QRP QSO with Brasil
After 8 QSO's with 1 W and 2.5 W, I heard PY2WC calling CQ, so I tried 2.5 W.
I fell off my chair when Waldir answered: SAQ, which means that he was using QRP and this was a 2 way QRP QSO. It was only after a few QSO's, also with 2.5 W, I realised that I could have made the QSO with a lower power.
More than an hour later I heard Waldir again and made a second QSO, but now with 1 W (980 mW). Thank you Waldir for a new DXCC in QRPp, thus less than 1000 mW.
Tip: Just make a second contest QSO, with a lower power if you can.
My most memorable very low power QSO with 0.85 mW with RT6A is a Dupe. hi
"More than 1000 MPW" QSO's
This list shows only the 1000 MPW QSO that are confirmed via eQSL.
I actually made many more 1000 MPW QSO's in the CQ MM DX.
After I receive an eQSL, I determine the distance using the QTH Locator and the Miles per Watt.
I place the 1000 MPW info in the comment field of the return eQSL.
E.g. 2.5 W and 6062 miles to GG66un gives 2425 miles/watt - 73, Bert
Most QSO's were made on 21 MHz.
Although I made many DX QSO's 34% of the QSO's were made with QRPp.
And 70% with more than 1000 MPW.
In total I made 56 QSO's in the CQ MM DX contest. I worked SA, NA EU and SA. I had great fun.
My RIG is a FT-817 and the antenne is an Inverted Vee.
I always use QRP, but never a fixed power of 5 watts.
Thanks to all the excellent operators that made this contest QSO's possible.
