I've been listening again this morning on 40 CW, 7030-7060 and I'm seeing a familiar pattern. One frequency with the 300 khz filter on, and two guys calling CQ at exactly the same time. More than once, more than one frequency. Usually on a frequency ending in a digit and 000. 7051000, 7031000, etc. I use the digital readout and also the little zero indicator on my Yaesu to help peak a signal in the bandwidth I'm using. It's a bit of comfort trying to zero beat or close, but what's wrong with calling CQ on 7131368 or 7054735???
