I did some more playing with the 219 9mhz filter last night.

I have tried it in both of the n1 and n2 positions. N2 has the inrad roofing
filter in it also. No difference in either position. I get about a 10 db
loss which is what T T says is the loss in that filter.

This is regardless of how I play with any other functions, PBT,NR, etc.

This is for weak signal DX on 80&160m. Other bands dont need it. I am just
trying to lower the QRN to sig ratio.

Thanks for all of the replies and suggestions. I guess it is back to the
500hz filters.
