Thanks for the detailed reply, Roger. I have Ten-Tec's #219 and #282
in my N2 positions, so I should probably change my order with George
from the #765 to the #763 since the center frequency of the #219 and
the #763 will be offset from each other by 250 Hz. Guess I wasn't thinking
about the fact that Inrad roofing filter and the Ten-Tec 219 are both in the
same IF chain with no way to offset between them. Thanks for setting
me straight.

I am looking forward to ginving the Omni 6+ a workout in the CQ 160
CW contest in a few weeks.
