The Housekeeping Alternate channel was confirmed as Group 13, even though the channel is numbered 14. Ch. 6 and Ch. 7 were hard to nail down. They were both related to shows/entertainment and Fright Fest, but it was difficult to figure out an exact use for each channel. Ch. 8 was rarely used, but one time "officers" were talking, so it may be an alternate security channel.
