[TenTec] Fw: Inrad 763 vs 765

Being an ex musican, I can tell you that 50 Hz difference will be in the
passband of the filter. I assume you know how to measure the bandwidth of
your filter.

Hi All,

I just ordered an INRAD roofing filter kit for my Omni 6+.
Initially I specified the INRAD 765 (centered on 500 Hz
offset), but now I am wondering if I wouldn't be better
off with the 763 (750 Hz). I was just playing around with
the pitch control on my FT1000MP MKV, and I tend to
gravitate to a note that is between 600 to 650 Hz offset
which is right in the middle between the 763 and the 765.
Will either filter accommodate this note, or is one going to
be better than the other for this in-between note (I noticed
that the frequency response plots of the two filters aren't
exactly symmetric).

Thanks,

Mike W4EF.............................
