[Elecraft] OT-Preserving CW memories

[Fred Jensen]

Well, YMMV ... but I'm sort of with Ron.  I like to know what's going on
around me, and if I want to really dig in and pull someone out of the
noise, I know I can do it (well, sometimes!).  I retired from
communications engineering, and I accept all the theory for channels
subjected to noise and possible throughput as a result, but we're not
"Point-To-Point" folks.  I'm not totally sure that it applies to the
operation of a ham radio station.
