Pete has a good point.

Another reason is the disparity of rigs/filters.  When I have my filters
tightened down to 250Khz with DSP on,  and the roofing filter and the 40M
yagi are in line with big signals everywhere,  I may see daylight but some
one with wider filters, no roofing filter and a dipole may see QRM.
