I've worked a lot of station in a DX contest that were operating ** in between
** the DX and his split pileup. Was there lots of confusion? You betcha,
however Tom's point is valid. With a wider split the frequencies in between are
essentiual vacated and available for others to use.

n 500 Hz of width (+ - 250 Hz) they use 500 Hz from 7.00475 to 7.00525 kHz. If
they listen up 500 Hz, they simply move that 500 Hz slice up the band from
7.00525 to 7.00575 kHz.If they move it 5 kHz or 100 kHz up the band, they still
"hog" the same total space.I'm trying to figure out what people are trying to
say, because it has nothing to do with the split distance once it is all
outside the one transmit channel width.73
