WJTP
WJTP is an AM radio station broadcasting on a frequency of 890 kHz with 5,000 watts of power during daytime hours only. The station is licensed to Lithia Springs, Georgia, a suburb of Atlanta. Its signal is transmitted from a facility closer to the city of Atlanta, Georgia as it shares the broadcast towers of WAOK AM 1380 near the western interchange of Interstate 20 and Interstate 285. The station is currently owned by James Su.
Because WJTP shares the same frequency as " clear channel" station WLS AM 890 in Chicago, Illinois, this station only broadcasts during the daytime hours.
