More recently, Steve (K9AN) and I developed an open-source Reed Solomon decoder for the (63,12). Many messages about this work are in the wsjt-devel Archives, and the code is now part of WAJT-X, WSJT, and MAP65. The Koetter-Vardy decoder is no longer used by any of our programs. Steve and I have written a paper on the "Franke-Taylor" soft-decision decoder. It will appear next month in the ARRL journal QEX.
