Transmitter
In 1987 KRLA moved its transmitter site from South El Monte to Irwindale, where a similar antenna array was installed. During the 1990s, KRLA was authorized to increase nighttime power from 10,000 to 20,000 watts. When the power increase went into effect, KRLA started broadcasting from a new transmitter site in Irwindale, California. This is a few miles north of the old El Monte site.
The El Monte transmitter building still stands as a shell. The entire inside is burned out, however there are still clues to its historic past. There are numerous ducts to keep the equipment cool and an underground channel to divert the cooling water for the transmitters. A well nearby supplied the water. Still visible is the wooden archway where the transmission cables gently bent toward underground conduits running to the transmission towers in the nearby field. All that remains of these towers are the 4 concrete bases, still lined in a perfect row.
