I have noticed that with some of the sounds in ECW, they are almost “flickering”. The AWS alarm is almost pulsing in both 377 and 66. It is also with the horns too. Especially for the 377. I’m not sure if this has been logged, it probably has, but I thought I’d add it anyways. I haven't got the facilities to record the noises, but I am hoping that others know what I am talking about. Cheers.
