KCBS-FM
KCBS-FM is a radio station in Los Angeles, California broadcasting to the Greater Los Angeles area on 93.1 FM. KCBS-FM airs an adult hits music format branded as "Jack-FM".
Unlike other radio stations of similar format, the Los Angeles Jack FM playlist runs a fairly focused playlist of popular classic rock and Alternative Rock tracks. Currently, the station has no air staff save for Tami Heide with her "Jacktivities" (events and whatever announcements deemed worthy by "jack"). Unlike most other stations in this format, the call sign no longer includes any form of the word "Jack," opting instead to hold over calls from a previous format. This is similar to its FM sister station in New York, WCBS-FM, which had maintained its WCBS calls during its run as "Jack FM."
Although Jack proclaims that the station is run "in a dumpy little building in beautiful downtown Culver City", KCBS-FM is actually at the intersection of Venice Boulevard and Fairfax Avenue in Los Angeles, about ½ mile north of Culver City. The station's transmitter is based on Mount Wilson.

KNX (AM)
KNX is an AM broadcast radio station on 1070 kHz in Los Angeles, California, United States. It runs an all-news format. The station is owned by the CBS Radio subsidiary of CBS Corporation. KNX continues to hold a Class A license from it being one of the original clear-channel stations allocated under the 1928 U.S. band plan. KNX broadcasts from facilities shared with sister stations KCBS-FM, KTWV and KAMP-FM located on Los Angeles' Miracle Mile; its transmitter and antenna array site are located at Columbia Park in Torrance (northeast of the intersection of Hawthorne Boulevard and 190th Street).
The station also broadcasts a HD Radio signal, streams online, and simulcasts on the FM band on KAMP-FM-HD2, and on KTWV-HD3.
History
KNX began as a five-watt amateur radio station, 6ADZ, which Fred Christian put on the air on September 10, 1920, broadcasting on a wavelength of 200 meters (1500 kHz). In December 1921, the station moved to 360 meters (833 kHz) and became KGC, sharing time with other stations that broadcast on the same frequency. On May 4, 1922, the station increased power to 50 watts and became KNX. Power was raised to 100 watts in 1923. A year later, Fred Christian sold KNX to Guy Earl, owner of the Los Angeles Evening Express.
KNX (standard)
KNX is a standardized (EN 50090, ISO/IEC 14543), OSI-based network communications protocol for building automation. KNX is the successor to, and convergence of, three previous standards: the European Home Systems Protocol (EHS), BatiBUS, and the European Installation Bus (EIB or Instabus). The KNX standard is administered by the KNX Association.
KNX protocol
The standard is based on the communication stack of EIB but enlarged with the physical layers, configuration modes and application experience of BatiBUS and EHS.
KNX defines several physical communication media:
KNX is designed to be independent of any particular hardware platform. A KNX Device Network can be controlled by anything from an 8-bit microcontroller to a PC, according to the needs of a particular implementation. The most common form of installation is over twisted pair medium.
