hello,
using a TS-480S remotely for several months now without any problem.
Yesterday it started with the following problem:
After a while, it could be a couple of minutes or just a few seconds, the frequency on the display disappears. I see a line of dots instead.
At this point it let me change the filter width, NR parameters, etc, but I get no audio and cannot transmit.
When it does that, it sends a CW "UL" message.
Any idea about what it could be?
