SEPTEMBER 2018 • FOGHORN 19 FOGHORNFOCUS: TECHNOLOGY 5. Turn on the LED light(s). * If the radio now outputs audio noise, then the LED lights have raised the noise floor. (Noise floor is generally the amount of interfering signal/static received beyond the specific signal or channel being monitored.) 6. If the radio does not output audio noise, then the LED lights have not raised the noise floor. If the noise floor is found to have been raised, then it is likely that both shipboard VHF marine radio and AIS reception are being degraded by LED lighting. In order to determine the full impact of this interference, the Coast Guard requests those experiencing this problem to report their experiences online to the Coast Guard Navigation Center at www.navcen.uscg.gov. Select “Maritime Telecommunications” on the subject drop down list, then briefly describe the make and model of LED lighting and radios effected, distance from lighting to antennas and radios effected, and any other information that may help understand the scope of the problem. n Kenneth W.
