[TenTec] 221 cw filter insertion

[Struwetzel at aol.com]

If I understand the way the Omni VI works, signals
first go thru the  roofing filter, then 9 MHz 2400 Hz, then
through the optional NAR 9 MHz  filter before going
though the 6 MHz filters.  This means you will  see
about 13 dB additional insertion loss when the NAR
filter is  selected,
 
But doesn' t  the Omni6 + have a similar gain adjustment for high loss  
filters as the Orion? That is, for the optional 9 MHz filter there is a  jumper 
plug that can be set to at least partially compensate for the higher  losses from 
the 216,217 219 and ,yes, the 221  filters.
