Rod FYI: The "NATOPS FLight Manual" (for C-121J, EC-121K/M, WC-121N, NC-121K aircraft), NAVAIR 01-75CKC-1, dated 15 April 1971, lists the C-121J (R7V-1) intercom unit as being AN/AIC-5B; it was AIC-10 on the other birds. Also, the CU-308U coupler was what switched the long-wire antenna between the APN-70 LORAN and ARC-38A when they both tried to share the RH overhead long wire antenna.
