On February 25, 2010, an agent of the Commission’s Dallas Office inspected/monitored radio station KLLL, located at Lubbock, Texas, and observed the following violation(s): a. 47 C.F.R. § 73.317(d): “Any emission appearing on a frequency removed from the carrier by more than 600 kHz must be attenuated at least 43 + 10 Log10 (Power, in watts) dB below the level of the unmodulated carrier, or 80 dB, whichever is the lesser attenuation.” At the time of inspection, the spectrum sample from radio station KLLL had spurious emissions on 95.0, 97.6, 97.8, and 99.8 MHz which were not attenuated as required. 3. On February 25, 2010, during the inspection, radio station KLLL had a spurious inter- modulation product emission on 109.15 MHz. The inter-modulation product included audio from 95.5 MHz, 102.5 MHz and others. The modulation from the 109.15 MHz inter-modulation produced varying signal levels on the Lubbock Preston Smith International Airport Instrument Landing System (ILS) channel 109.5 MHz. The signals on the ILS channel were observed at one mile from the transmitter site as high as 30 dB above the channel noise floor and below the minimum attenuation level required by section 73.317(d) of the Commission’s Rules. Although below the emission mask in section 73.317(d) of the Commission’s Rules, these signals appear to be the cause of one of the reports which placed the ILS out of service, specifically a report of disruption in 1 47 C.F.R. § 1.89.
