SDVLCC has a master list of Orion (Yellow/Blue) transponders which can be accessed via Transponder Database
This has been used to assign the transponder numbers allocated for this race. Note that there were a significant number of entries where the transponder number nominated was incorrect so if you are unsure in the future please use this site or leave the number blank.
While an attempt will be made to check all transponder numbers at registration those entries flagged with TRANS CHECK are important to be checked as these may be nearing end of life.
