Mike,
   
  I fully agree with you - mode B still baffles me and causes the infrequent 
error.  At least with mode A when I press the paddle I'll know what I'll get.  
The K-2 has mode A, which is a lifesaver in the pileup.  When chasing DX you 
don't need the extra character as that is the time they will hear you.
   
  I'm curious about the Jackson Harbor aftermarket pic, I think it also 
increases vfo resolution to 10 Hz doesn't it?  Please drop me a note off list 
as I might wish to upgrade my DSW-II.
   
  Regards,
  Joe N9JR

    Mode B timing IS much more critical than mode A because if you hold the dit 
paddle just a tiny little bit too long in an iambic dah-dit string, you'll get 
an unwanted dah, and if you hold the dah paddle just a tiny little bit too long 
in an iambic dit-dah string, you'll get an unwanted dit.

With mode A, you only get a dit or dah if you've pushed the dit or dah paddle 
for it. To me, that just seems the logical way for a keyer to work. Given that 
there is no discernable advantage to mode B, why anyone would want a keyer to 
send a character element for which no paddle was depressed has always baffled 
me. Historically, mode B arose from a logic flaw in an early electronic keyer 
that eventually got advertised as a "feature."

  But...If one is just learning iambic keying, I would recommend learning mode 
B rather than mode A. Some ham rig manufacturers don't give you the option of 
choosing the logical system, and provide mode B only (like Yaesu and Small 
Wonder Labs). My SWL DSW units gave me fits because they had only mode B keying 
(until Jackson Harbor produced a full-featured keyer with mode A option as a 
replacement for the stock PIC in the DSW).
