1370 KFRO is a class B station. KFRO is 1 kilowatt day non-directional (1 tower), 1 kilowatt night directional (3 towers). The KFRO towers are 177 feet tall. The current KFRO transmitter building was built in 2003. KFRO signed on in 1935 with a 100 watt homemade transmitter. In 1935 KFRO increased power to 250 watts with a Western Electric transmitter. In 1941 power was increased to 1,000 watts and a new RCA BTA-1D was installed, it stayed in service until 1983, when it was replaced by a Rockwell Collins 820-D. The Rockwell Collins transmitter was made to run C-Quam AM Stereo, which made KFRO the first AM stereo station in East Texas. The Collins-Rockwell was replaced in 2003 with a used 1975 Harris MW-1 solid state transmitter which is still in service.

Famous quotes containing the word engineering:
“Mining today is an affair of mathematics, of finance, of the latest in engineering skill. Cautious men behind polished desks in San Francisco figure out in advance the amount of metal to a cubic yard, the number of yards washed a day, the cost of each operation. They have no need of grubstakes.”
—Merle Colby, U.S. public relief program (1935-1943)
