This is prettying how I use it, too. The main rx has the arsenal needed to
handle hearing the DX. I only have problems when the pile is filled with
nearby, strong signals and the DX is working someone with a weal signal at my
QTH. I may not hear that guy and so don't know the freq of whoever the DX is
working.
