" So even though some here consider kiloWatt QRO perfectly consistent with operating a weak signal mode and CFR 97.313(a), " Weak siqnal mode does NOT mean Low Power mode. It means that the program and mode are capable of being decoded and low thresholds. Did you know that these programs were initially for Moonbounce where stations regularly run 1 Kw ? Using enough power to make and maintain a contact is variable. If you are running 500W and all the stations you QSO with are giving you +20 signal reports then yes, crank it back. If a station responds to your call with a -23 then you are wise if you double your power or more to complete the contact given QSB, QRM, QRN etc. If you are calling a DX station on a clear frequency and he is not answering you on 40w then double the power and call again. If you have fun running QRP and that's a challenge for you then have fun !
