Tom51 Posted May 1, 2019 Share Posted May 1, 2019 Has anyone ever put a bluetooth transmitter in a G scale train and had the sound transfered to a outside speaker. I have the MTH BB and would like to have the sound picked up by a speaker in my yard. love the sound but would like the neighborhood to hear it also. if this can be done, how was it done.
