[Elecraft] [K3] AM & FM Filters

[Terry Schieler]

I am "building" a K3S on paper and have a filter question.  I am told that if I want AM and FM transmit capabilities I can just order the 13kHz FM filter and save the price of the 6kHz AM filter.  Certainly seems logical that the 13kHz FM filter bandwidth could handle the 6kHz AM signal (no interest in ESSB).  Just curious as to whether there are any unforeseen bumps in the road in doing this.  Makes me wonder why anyone would order the AM filter if the FM would cover both.  
 
Thanks.
