Depends on what you use the radio for, the AM audio bandwidth is limited
already, this mod reduces it more - and takes a chunk out of NFM too.

BUT on a crowded SW BCB band its great, no more filter skirt blow by, as
the 545 has about 45db rejection at this DSP stage for an IF its really
crap (the R8 and R75 are way better), the new filter helps a lot to
avoid the odd effects you hear when stations are within its 10-15Khz
pass band.

Worth trying one with it - or hear an audio sample but I only really do
UTE stuff and its great, the audio quality is not the thing I got the
radio for.

DaveZ has some comments about it on this www page, along with some DSP
comments that might help you on the purchase of the filter.
