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

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). _______________________________________________ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
