Several days ago I acquired a beautiful Omni 6+ (564), and love the 
radio  One glitch that I notice is that occasionally the speed of the 
keyer will  vary slightly (speedup by maybe 1-2 wpm).  Since the effect 
seemed to be more prevalent when running my linear amplifier vs barefoot 
I suspected rfi getting back into the keyer.  I then wrapped 7 turns of 
the cable from my paddle through a type 31 split core ferrite, right 
where the cable is connected to the radio.  Although the keyer 
instability now occurs less frequently, it still does occur.  It's not a 
show stopper, but is annoying.

Any comments/suggestions are welcome.
