I have two new Railking RS-3 engines. I am running DCS release level 3.11, I am running the engines individually, "not in a lash up". When I initiate the SXS soft key on either of the two engines, I get two or three seconds of a continuous very high pitched sound. I do "not" get the horn sequence of two long blast followed by a short and then a long blast. I have multiple PS-3 engines, both steam and diesels. The SXS soft key works as expected.
Has anyone else experienced this problem. Anyone know of fix for this problem.
