[Elecraft] K3 APF Problem

[Eric Swartz - WA6HHQ, Elecraft]

If you enable advanced mode in the utility preferences, you can chose to 
only load specific files.

Be careful with this, as DSP, CPU, FPF files etc from a release must all 
match the release set.  That's why we recommend clicking on the 'load 
all files' button.

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.
