I got a supposed Ten Tec model 217 filter for the 9 MHz IF,
500 Hz for CW use. It has funny numbers on it, not "217"
though. Anyway, I put it into the NAR1 position on my OMNI,
and I like it and all. I also have the 219 250 Hz filter in
the NAR2 position. I flip between the two and notice that the
500 Hz filter has a much lower center frequency, right where
I like it. The 250 filter is much higher in center, very
noticeable. It seems I got one of the special order filters
that was designed for a lower center by sheer accident!
Now, to order the 250 Hz filter with the lower center, and I
will have my CW station in order :-) . This is great, what
luck!
