[Premium-Rx] EK895 RECEIVER INFO REQUESTED

[Pat1McA at aol.com]

Greeting All,
 
I am investigating the Rohde & Schwarz EK895 dsp receiver and  would be 
grateful for some information please.
 
1. When were they first produced?  c.1993 or later?
 
2. Any idea of the Firmware Revision numbers against the receiver  
manufacturing date?
 
3. Are there "Early" and "Late" models?   Similar to the  WJ  HF1000/WJ 
8711A  scenario?
 
4. Would "Early"  production models be upgradeable to the  current version 
or are there subtle hardware changes that prevent this  being possible?
 
If you do not ask you do not get and I really am hitting a brick  wall on 
these questions.
 
I know that there are EK895 cognoscenti  lurking out  there!  Please 
contact offline.
 
Many thanks,
 
Pat G3YFK
