Ah yes.  I believe I understand.  

Sat hears nothing ... or Sat hears nothing but collisions and is unable to decode anything. IN either case ground station hears nothing from Sat.

Hmmm.  Interesting probem.  
Sounds like a fix is to beacon when hearing nothing, but make it often enough to 'catch the sat in a pass' in hopes of being decoded...  (sorry Mr. Battery.  (;-)  
[Or have a pass schedule with you or in the software...]

Thanks, 73, Steve, K9DCI
