            Abstract : 
H.f. communication receivers have progressed towards a high level of sophistication yet a high percentage of reception failures are still due to limitations within the receiver. This paper considers the role of frequency selectivity for an ideal receiver and proposes a costeffective approach which should noticeably reduce reception failure.
