Andy, the latest opera software (v.1.4.9) includes a 65 rate. It's a pain to download but it can be done. Spec Lab does include a number of transmission modes but I'm not aware that opera is one of them, and certainly not this new, latest rate. There is no deep search code for rate 65 that I'm aware of either. -- 73, Garry, K3SIW, EN52ta, Elgin, IL
