Back home now (and using a new D-Cell battery!)...F6HKA replied to my CQ on 15/7/11. Bert began with 400w on his end but quickly dropped down to 5w. I had a perfect, 549 copy of his signal with my 20m receiver made from a diode mixer and a one-transistor audio frequency amplifier. His, "VY FB INCREDIBLE" CW exclamation translates to a Milliwatter's "home run." :o)
Bert emailed later, "Your 85mW doing a very nice job and your report was really 559." We had a very solid contact lasting some ten minutes....a wonderful QRP/QRPp QSO!
