[TenTec] Omni6+ roofing filter

[Clark Savage Turner]

The little filter ahead of the rest in the 9 MHz IF can be replaced by a 
nice, narrow filter as George at INRAD did.  It helps some, but it is 
not much of a deal as the front end is already designed reasonably well 
(there is only so much you can do if you are already in good shape :-).  
The "other" rigs with high VHF IF's and wide filters have much more to 
gain by a narrow filter up there to protect the next mixer.
