[CQ-Contest] Spacing note for RBN users

Hi Joe, 


The good news is you'll have a lot less QRM during contests because 
the skimmers won't reliably detect your non-standard Morse spacings...

Hello Pete, 

Two questions. 

Does Farnsworth spacing's have any effect? I like to run my letter 
speed at 25 to 30 wpm, but the say "Word" speed at 20 to 25 wpm. 

and 

Varying spacing's, Like our club call W9ET if i run it "as is" I get a 
LOT more repeats. 

But in like N1MM+ if I use W9~e~T insert the half spacings, I almost 
never ever get any repeat requests. 

One More I havent tried it yet, but to emphasize the "T" in the call, 
say I'm running at 25 wpm, but just for the "T" I drop to 20 or even 15 
to emphasize that it is a dash. and make it really obvious the 
difference between the "E & "T"
