[1000mp] Yaesu FT1000 Key Clicks

Earl,

Did you do any experimenting with that 8 ms rise time as a function of CW
speed?  I've been hearing some amount of soft CW of late and I'm wondering
to what extent slowing the rise (or fall) time affects the readability of
higher speed CW signals.  I'm talking human copy of speeds in excess of 40
WPM, as opposed to computers' doing the work ;-)  Thanks.
