Did you listen to them working DA0HQ and calling
CQ at the same time on the *same* band?

Hi Jeff,
as you wrote, what I mean is that I heard them at the same time.....

Anyway let's suppose I 'm wrong.....

Considering that all usual big M/S (like @ir4x,where I experienced it) have two rigs at RUN position which allow to work new mults and new fresh meat on the same band, and moreover  let's suppose you haven't multiple sigs at the same time,  I wonder how can they pick up calls and hear something on TX-2 while trasmitting on TX-1 using same or different ants(remote ants not included)????

In last CQWW2003CW I did it at RUN pos and I was able to hear only when TX-1 was listening too.

In other words are you able to erase, not completely but decently, your TX-1 signal 10khz far away from your TX-2 in order to hear something that isn't your RF???

I 'm pretty interested in this because it would be great for an SO3R. I also talked with some friends that worked at a big multi-multi stn (I3MAU-well known during 1980/1990) but they didn't find a soultion.

Anyway SCC, as you can see in 2004 EUHFC rules is trying to fight against multiple sigs at the same time on the same band.......so this phenomena at least exist.
