[Yaesu] Inrad Filter

Thu May 5 15:53:38 EDT 2005

I have bought and install Inrad Crystal Filter #701B for mt MKV Field.
This is for second (8.2MHz) IF.
Thay advertize it as 400Hz.
I do not see any difference between stock 500Hz filter and Inrad 701B.
Is anybody actually measured it?
I was hoping for a bit better rejection for RTTY and CW but I am a bit
dissapointed.
Any opinionon 250Hz inrad filters for second and third IF?
