You can read in the side bar of the WSPRnet.org that: QRP for our purpose means 500mW or lower. The last 2 years I thought that 5 watts was QRP, and in the beginning I thought: will anybody ever hear me with 5 watts. But I did, in one year I worked 76 DXCC, most of them with SSB. Everything is relative. Since I work with WSPR and JT65A I know that I can work with 50 milliwatt the same distance as with 5 watt SSB. A discrepancy of 20 db. Thanks to Joe Taylor K1JT for his fine software. Because without the WSPR software we weren’t able to ‘hear’ signals -25 db or lower. I even decode signals with -33 db. I began to think in terms of 5 watt is QRO.
