Abstract
The deceptively simple problem of a single inverted reflection in ordinary frequency modulated (FM) radio is considered. It will be shown that this problem has been overlooked in the literature and causes major breakdown in reception. The problem is known as suppressed-carrier AM-FM (SCAM-FM) and is totally destructive to the received signal. We examine the theory and practical measurements of SCAM and show a solution for reducing its effect.
