[Icom] Wider SSB bandwidth on IC-756

	In a review comparing IC-756 and 756Pro/II, W8WWV states the following:

NOTE: In January of 2002, I learned that some amateurs had discovered that
models of the 756 past a certain serial number were built with a
normal/wide transmit audio bandwidth switch. The serial number of the
change appears to be around 3,000. The switch is totally undocumented, and
is located within the radio. The switch, S801, is on the bottom of the
radio. I do not know where it is located. The swiched is marked N (normal)
and W (wide). By default, it should be in the N position. If you move the
switch to the other position, your transmit audio bandwidth will become wider.

	Can anyone here confirm that? And comment on how the "Wide" setting would
compare to using ICOM's FL-257 3.3kHz filter? I don't work SSB, but
thinking about doing so, and am intrigued with the "Hi-Fi SSB" concept.
