I just came back from the boat and turned on my VHF together with all the LED cabin lights and the masthead LED tricolor/anchor lights. I did the squelch test as described in the CG article. I did not notice any difference in the set point of the squelch. I listened to transmissions over channel 16 and the weather channel and did not notice any change. I also monitored the AIS and did not notice any issues. 
My LED cabin lights are from Dr. LED and the masthead light is from Aqua-signal 34 series. I will keep monitoring the situation to see if anything changes.
