Just to prove that TR was way ahead of the curve.

When Tree first did TR log it sent CW by sending the data
out to his AEA MM-3 on the serial port.  
It had this support in it for a long time - and may still
have it in there somewhere for all I know.


George Fremin III                   You know you've achieved perfection    
Johnson City, Texas                  in design, not when you have nothing
K5TR (ex.WB5VZL)                      more to add, but when you have nothing                         more to take away.
