Signal/One CX11 Census

August 2017 - Bill Turini, KA4GAV has done extensive research on the status of ALL CX11s.  I assisted Bill a bit with this project but the
vast majority of work was done by him.  The spreadsheet linked below is compiled from information in Paul Koller's
original notes and information in the CX11 Registry that I have gathered over the years. 
Unfortunately it seems that many of the last known owner's call signs are not active or have been reissued, leading us to believe the
owner is now SK.  So in many cases we must assume their radio is "lost".
Each entry has the original owner listed first and all other owners listed in order below.
If you notice any errors please contact Bill or me.
So here is it.  A lot of information and history on the Signal/One CX11 and CX11A.
