My ISP had a major meltdown resulting in a completely new IP setup for me at my station. I bought a new router to replace a very old one and reconfigured the settings. All was working well with my TS 480 for a while but now I have this "noise" on the system that is not dependent on any setting on the 480 control head - band, mode, even volume setting. The noise is a constant and more or less rhythmic pulse of about 1000 hz (almost like a string of CW DITS at 20 WPM.) At times it will go away for a few seconds but returns.
It must be something on the internet connection itself, but I have checked every setting on the router and RR. Interestingly, the TS 480 is working normally - I can receive signals and transmit except for this background noise which of course makes listening difficult.
Does anyone have an idea of what is causing this problem? I have an mp3 file that I can send to a private address if anyone can help identify the problem. Cannot upload mp3 here.
