And won't that 5 WPM CW step on the hidden station anyway? Why 5 WPM if I can copy 20 WPM and more? 20 to 22 WPM is a usual speed for a satellite beacon, for one example. Well, probably with the new breed of morseless operators already showing up, any speed of Morse Code will be tagged as QRM. It is the proverbial snake biting its tail... It seems that the QRL signal is the only thing new out of this long inefficient discussion. (A zillion bytes in, three bytes out) And, taking it to the extreme, it could be tagged as QRM too...
