[Elecraft] ECN spreadsheet data

[kevinr at coho.net]

I have the ECN data from before the hard drive crash but cannot read it. 
I have tried LibreOffice and OpenOffice.  Neither application wants to
open an .sdc file created with StarOffice.  Does anyone have a clue for me
as to how I can open ECN.sdc so I can transfer it to one of these more
modern applications?
