I didn't get up early enough but did catch the last hour. Host at least did mention that the codes used were not the same as Continental (radio) code, using letter "O" as an example of the difference.
Mostly just a chat show and wandered off a bit into the story of Kate Shelley, Harvey Houses on the Santa Fe, etc.
Thanks for letting us know.
