The CV-60 and CV-89 should do fine on the 450 cps shift.  So will the 
Boehme 5C, which is audio filter type with one fixed frequency filter and one 
tunable one.  But I know that back in the years when it was in service, I know 
that the 5C struggled at 170 cps shift.  I don't recall ever trying either 
of the other two.

I haven't looked to see whether or not I have it but Nick reported a field 
change to the CV-89 to improve its performance on narrow shift.  But I never 
saw one run that had the mod.
