Soundtrax Tsunami 1000 in Bachmann J Class

[NW Modeling List]

Hi Barry;

 

To get it exactly right, you will need a sound cam (wiper) on one of the
drivers so that the decoder knows exactly where things are.

Hello, 

 

I have an HO Bachmann J which I fitted with a Soundtrax  Tsunami 1000
decoder. 

 

I cannot get the chuff rate to match the wheel revs at  low speed. I have
been through all the Soundtrax instructions and played for a long time with
the CV values, but it is still not right. 

 

There should be 2 chuffs for every movement of the crosshead along the slide
bar. So when the crosshead gets back to the beginniong of the cycle there
have been 4 chuffs. Currently there are 2.5 chuffs.

 

Has anybody done this conversion please and If so have you have managed to
get the chuff rate to match wheel revolution? If  you have would you let me
know the CV settings please.

 

Everything else is fine: whistle, bell, lights and general sound effects.

 

I use an NCE Power Cab.

Many Thanks
