QTR-Quadtone RIP

Tom,

I've been struggling with the QTR 2.2b linearization process for a 
while and joined this forum recently to try to find some answers. 
Looks like you may have some soon. Any idea when the new user manual 
will be ready? It'd probably be more worth while to wait for it 
instead of asking questions here that may be answered by it.

Thanks,
