I'm in the process of switching from my "test" layout to my permanent layout. The new layout is much larger (around 15 metres of road in total). I have split the layout in two and am using both transmission loops on the UCCI.
I can hear a high frequency whistling noise coming from both of the the transmission loop. This wasn't present on my smaller test layout. The vehicles respond perfectly and obey all commands.
Has anyone else had this issue? Many thanks in advance.
