[TenTec] Tentec Filters in General, 1st IF and 2nd IF

[Allan H. Kaplan]

I believe that you might do better cascading filters in Omni by putting
the narrower one up front to better protect the following stages from
close-in QRM.   Of course, its fairly simple to try them both ways.  You
can test both configurations by evaluating what you hear quite  close to
an S9+++ signal.   Using the narrower one after the wide one would work
better for Passband Tuning.
