From The RadioReference Wiki

Previously believed by the community at large to be a MEROD fabrication it has been revealed that the system actually exists. MEROD (Message Entry and Read Out Device) is the commercial name for the Racal manufactured equipment that uses the RAC-ARQ mode. This FEC system is documented to run at 150 and 267bd using a "wide shift FSK". This system documented heavily in the Radioteletype Code Manual 13th Edition from Klingenfuss with signal samples available on the Klingenfuss Modulation cassettes on track 38.
