SCA Monitoring Delay Asked A 6 -month postponement of the FCC's proposed rules requiring FM stations to monitor subcar- rier generator frequencies has been requested by the NAB. If granted, the new rules would take effect Jan. 5, 1967. NAB told the Commission that subcarrier fre- quency measuring equipment is back -ordered several months and is therefore not readily available. At deadline, both McMartin and Rust Corp. contacted BM/E to re- port the availability of new sub - carrier frequency monitors in time to meet the deadline. Educasting Systems, Inc., N.Y.C., has received a patent on an instruc- tional materials program service adaptable to FM or CATV systems.
