depends on where you live & who you hear. in this part of the US, at this time in the cycle, we don't hear much NW corner, or west side at all. no prime in many years(didn't he also use 'big 9' back in the 90's?), never heard '40 mobile'( :mrgreen: ), though i must say (clarence) crack (carter) does have a presence here, even when DX is generally not reaching that far. during the spring/summer seasons, the big boys include mean pill, yellow jacket & big relay in the midwest, 148, steel jacket & huckabuck in the southeast, 187 & painkiller in the northeast. could probably name 50 other stations capable of talking daily on the bowl when the 1 or 2 biggest of the big boys aren't there. have more then a few QSL cards from some big boys of the 70's floating around here.
