[Elecraft] CW Keying characteristics-computer vs Bencher

[Ralph McClintock]

Don,
The computer generates an on-off. Writelog does not allow any adjustment of
keying characteristics. The Bencher generates an open or ground. Why does
the K2 recognize the Bencher, a mechanical switch, as soft and why does it
recognize the computer as hard?
