Don, 
 
I will send you my SHS units soon for doing the upgrade.  
 
I assume you do not do this for AM units.

sound.

Dear Earl,
We are now installing the QSI revolution U DCC sound decoders  in 
our F units over the Tsunami. The QSI's are rated at 1.5 amp vs.1.0  
of the Tsunami. This is important with our F7s with Mars lights as  
they draw more and this is esp. true going up grades with long 
trains.  Also, there is an additional lighting function which is 
important for F  units with Mars lights.
Don
