RMweb Gold Kaput Posted September 25, 2023 RMweb Gold Share Posted September 25, 2023 I have a KR Models GT3 fitted with Legomanbiffo on a Loksound 5. When the GT3 is on the track with power on there is a noticable buzz coming from it. No other locos seem to do this and other types of decoder (Tried a LaisDCC and another Loksound) don't make any noise, only Loksounds (Maybe ESU in general but I don't have any 21pin LokPilots to try). The GT3 runs perfectly normal and the sound works fine. Controller is a Z21 with track voltage set to 14V. Any ideas on cause and/or if its something to be worried about?
