Vic and all,

This morning I've reloaded all the K3 firmware and the problem has 
disappeared.  Guess the third time loading is the charm.  

Two suggestions for those that make decisions.  Put a feature in the utility to 
load only certain firmware rather than a complete reload.  There is a feature 
to upload only new revisions but nothing to reload only a single firmware.  
Second, zip a complete set of compatible firmware files into one file, unzip it 
in the utility and load from those files only.  This could eliminate the 
problem I had that took several emails and three days to correct.  Of course, 
individual files could be left on the server for those desiring to download 
individual files.

The APF does give a peak to weaker CW so it is a definite improvement.  I 
noticed very little ringing.  It makes the audio sound a bit more crisp making 
it easier to hear.  Guess that is a result of enhancing the "Q" someplace as 
has been previously discussed.

Vic, thank you for helping resolve the problem with my K3.

Take pride in the USA. 73



Jim, W0EM

Make sure DTBL0014.HEX is in the folder along with the DSP files. That's the 
DSP table for 
DSP 2.71. Then reload the DSP. I think this is the same kind of problem that 
you had with 
the FP -- out-of-sync files.
