Chuck,

Yes for sure on the HF-1000.  I am interested in seeing how its narrow
bandwidths work on weak CW.  I think we would want to use it at the
cottage and not try to take it into the field.  Both of our inverters are
free running oscillators so I cannot say they are clean. 

The Timewave would be interesting to try in both cases but at the cottage
alone would be helpful.  We will have several DSP boxes so we can compare
how they work on weak CW. Many DSP users want the SSB noise function and 
CW may be an afterthought on some of these boxes but the web page on the 
Timewave looked like they had the best CW specs.  Dave Wilson said yes 
but the NIR-12 seemed as good.  It will be interesting to hear both side 
by side.
