Ok...The keyer issue is a dead duck. Once I recovered from my temporary 
insanity I realized I was thinking of my IC-7000.
BTW: The best antenna for CW is a Windom. The dits and dahs automatically 
flow to the appropriate side of the feedpoint which insures proper 
transmission ratio. Just be certain your Windom is fed at the 1/3 point. If 
both receiving and transmitting stations are using Windoms, fading is 
virtually eliminated. One should take care to install the wire parallel to 
the ground otherwise dits or dahs will be missing, depending on the 
direction of the slant.
