Oops - I saw that after I hit the send button.  I meant to say insertion 
loss - my 250hz #751 has identical insertion loss compared to the TT 
#288 1.8kHz filter in terms of S-meter reading and listening via 
blindfold test (xyl pressing the buttons).  I tested a buddy's #288 
filter and his was quite a bit better in my radio so I think I just 
happen to have a lossy 1.8 #288.  I never use it so I don't mind.

I've had good success with INRAD's filters and George and Georgia are 
very helpful and patient.

Now if I could just afford an Orion!!  hi
