Right. A long time ago... lol.... really, it can be "so busy" now, that having an 18bps qso isn't something I look forward to. Being able to set a higher threshold means you don't need to guess as much on who you can hold a higher rate qso with. Likewise, I hear a lot of folks say they can hear but not be heard, setting a higher threshold, if wanted, would level the field in some cases. I for one, often see cq's in the 20s, but I can rarely contact them.
Like you dont want to see CQs lower then -15DB for example ?
what is the rational behind that ?
