During my venture into CW out of the radio amateur purest of the mode, was the desire to leave the SSB "Lid" operators. Lately, I have experienced the mostly "computer aided" , digital mode operators...and to a lesser extent CW operators not asking if the frequency is clear, ( mainly 40 / 75 m) with the station I'm having a qso with at 599, and the " Lid " at 599...no QRL nothing. Given the CW mode readability, I find it hard to believe that my station, or the one I'm having a qso with not being copied. So to the nub of it...listen and call if the frequency is clear 1st..I'm off my soap box, thanks. de WI4MM ..
