I'm definitely not volunteering taking this on, but it's not *such* a  
large amount of work. As I can see it, the tasks are

  - assemble the data in some format
  - get it into FG, alongside the existing navaids (there's also the  
potential to attach service dates to the existing navaids,  so they  
could be disabled prior to a certain date)
  - write a new kind of instrument (probably copying or subclassing  
navradio.cxx or adf.cxx) which does the range / detection math, and  
drives the appropriate output props (needle deflections or audio  
generation or whatever)
  - write the GUI for such an instrument.

Each of those is a pretty straightforward step, that I can see - not  
trivial, but fairly self-contained.
