Oh, I'll get hammered for this but here goes. I'd argue that the skill
level of the operator is inversely proportional to the width of the
split. Martti might ask for stations to call up 5 to 10, or maybe 5 to
15. He has a very high q/minute rate. When some ops say listening up,
and they really mean listening up 5 to 50, their rates go the the dumper
because they are spinning the dial way up trying to find one they can
make out and sometimes call a guy who could care less, stepping on other
operators all the while.
