DCC Decoder with a Class J whistle?

[NW Modeling List]

N&W passenger whistles on steam locomotives consisted of three tones, the
lowest normally sounding around 230 cps.  The other two created what
musically is referred to as a ³major triad².  The tuning of all three notes
could vary due to changes in the pressure of the steam passing through the
whistle.  Coincidentally, the SP G4s used the same whistle.  Soundtraxx
offers this whistle (as a G4) in their ³large steam² Tsunami decoder.  They
also offer the Frisco 1522 which is a major triad.  BWL has 611¹s whistle
programmed into their N&W class J decoder, but the tone is very raspy
compared to the real thing, and I don¹t know if you can buy the sound
decoder separately.  I recommend the Tsunami ­ or if you need a little more
current capacity, use Soundtraxx¹s DSX sound-only decoder and put some 1.5
amp power decoder in parallel to run the motor.
