I do not have a problem. I can see es hear them all but I am disappointed
how weak my signal looks on some of the EU grabbers compared to yester years
and some cannot hear me when I call for a QSO. Likewise they cannot hear/see
each other except they are vy local to one another.
BUT I do not use Probes OR Small loops. I use what one would call normal
LF/MF antennas.

Mal,

  Don't discount the increased interference from switching power
supplies, plasma televisions, PLTs and the like.
Everyone is battling a higher noise floor these days.

My suggestion: get a sail boat and operate from it!
