Reply to "Sound Decoder for SP 4-10-2 ?"

Jay COGR Forum Member

Ed,

I like the Protocraft Super Tsunami decoders because they can handle the higher current required for larger steam. The real problem is creating the correct sound cam (six lobes with a stagger able to create the desired off cadence chuff). I've often thought a hex shape with two of the opposing sides being much shorter than the other four might work.
