Thanks for sharing, DR.

How many operators here use Ultimatic mode? :)

Here's an explanation from Chuck Olson  -  WB9KZY of  Jackson Harbor Press about Mode A / Mode B. File attached.

 

I use Mode A and I use a genuine Curtis keyer chip - like MFJ has in some of their keyers.

 

Other manufacturers who manufactured Mode A did it incorrectly and you can complete a character and still make an error.

 

In correct Mode A once a character is sent and you let go, there's no extra dot or dash.  That's the way I want it.

 

I use Mode A and I recommend it because it causes fewer errors if your timing is off.
