Peter:
My findings are that the Tentec filters have less ripple across the passband
but the INRAD filters have a more symmetrical and sharper slope on both the
upper and lower sides. I prefer the Tentec filters in my Omni VI Plus.
You choice of a CW listening frequency will require the use of the INRAD
filters however.

Subject: [TenTec] (Inrad-)filter for OMNI VI - some advice needed
Hello list!
I am going to order filters for an OMNI VI+ but need some advice before
doing
so.
The question is: does the combination of the filters # 753 (9000.6 kHz)
and #
760 (9000.75 kHz) make sense or it is better to order # 759 and # 760
(both
centered at 9000.75 kHz)? I prefer to listen to a frequency of about 400
Hz
but do not want the af-frequency to alter when switching from 400 Hz to
250
Hz.
Another question is: do the above mentioned filters made by Inrad make a
real
advantage vs. those from TenTec?
