[Elecraft] k3s AM receive

[Rick Dwight]

I am going to order a K3S and have my filter selection figured out OK for CW and SSB.  However I want to do a little BCB and SWL listening on AM.  At this time no plans to transmit AM.  I live in rural Alaska and there are no strong BCB or SW broadcast stations close to my QTH.  Is there any reason to equip my my K3S with either the 6 kHz or FM filter roofing filters for AM reception or will the DSP filter do the job.  I realize that if I want to tx AM I will need to install the 6kHz filter.  My interests are 99% CW and my cw filters will include the 700Hz filter which I have already obtained.       Thanks,  Rick  KL7CW
