Dave Zucal posted:I added the two 10K ohm resistors to the line going from the main engine's speaker to the transmitter. What a difference in the sound quality. It totally eliminated the distortion caused by the amplifier. Not only that, the speaker no longer works like a microphone picking up room sounds and track sounds coming up through the wheels. You were right John and Willy Gee, the resistors do prevent the amp from over driving the transmitter. Thanks everyone for your input. On to the next project.
Did you have to add the MXR Octaver pedal to get the low frequency?
