[Elecraft] On the K3's CW keying envelope shaping, rise/fall times, and CW ALC

[Guy Olinger K2AV]

It ain't you.  They squeeze in to a QRO signal on a 40m 5 element
wide-spaced quad on a 220 foot catenary at NY4A.  It has to be the
bandwidth.  When I used an MP out there, people above and below used
to complain.
