[1000mp] Is there a better AM filter?

[Dean Fewkes]

I would love to use an inrad am filter but I do not think they make one 
that would directly replace the stock ceramic AM filter.  I think I 
would have to replace one of my 2.4 khz SSB filters but I am not sure 
how this would work with the limited ability to independently select 
filters on the MK5.

Has any body tried this?

Has anybody found a good direct replacement for the tiny ceramic stock 
AM filter?

Thanks!
