[TenTec] TenTec Digest, Vol 155, Issue 28

[Carl Moreschi]

The Orion has both a hardware noise blanker and a software noise 
blanker.  The hardware noise blanker is very superior and one of the 
best I have seen.

But the very best noise blanker I have ever seen is the software version 
in the Flex 6500.
