Paper QSL's

As a QRP and milliwatt enthusiast I make QSO's with low power.
With low power it is not that difficult to breach the 1000 Miles per Watt boundry.
Recently I received QSL carts for QSO's that are made with more than
1000 Miles per Watt.

36 Milliwatt & 671 Miles gives 18630 Miles per Watt

K2SX 1558 MPW  -  RG61PP 3430 MPW
W3UA 4325 MPW  -  ED9U 1530 MPW
