Agree with Ed. If you need WINKEY do it, if you don't why add to
complication?
Many of us don't. KIS.
I think it is a bit ironic that for RTTY, external TNC's have become
passe in favor of direct computer decode/encode.
However, for CW the direction is to the equivalent of a CW TNC-- at
least for the transmit side. So today we have to go via keyboard,
computer, computer program, PC port, PIC, PIC program and transistor to
emulate closing a J-38 key or bug.

Hi tech still uses 4 billion year old quartz and silicon to get their
performance.....
The K3 is made up of pre Sol stardust.
