Actually, Ron, as someone who does a LOT of AM BCB DXing, I can tell you, NRSC or no NRSC, there are times when I am very glad my communications receivers have a crystal filter. I lose some audio fidelity, but at least I can listen to the station I want without interference from an adjacent strong station. (Think: Splish Splash ! ) This is also a situation where sharply peaked IFs and a well aligned TRF stage before the 1st detector really help.
