[Hallicrafters] Hallicrafters SX-146 Reciever CW filter

[Lee]

I am going to totally restore my SX-146 receiver.  It has no accessory 
filters.  (CW and AM)  The IF is 9 Mhz.  Could I use an Icom FL-100 
crystal filter in my SX-146?  The Icom filter does have a 9Mhz center 
frequency but it was made for solid state radios.  I'm worried about 
comparability.  Same goes for load impedance on both sides of the 
filter.  I'm no expert on this subject.  Anyone on here with any 
knowledge on the subject?
