I am considering purchasing the Icom IC-R6. One of the determining factors, and my questions is, can it can receive FMN (I believe that is narrowband FM)?
From the ICOM IC-R6 specifications:
Mode: AM, FM, WFM
"FMN" is indeed short for "Narrowband FM", so this scanner, which receives "FM and WFM", will pick up such a station perfectly fine. (WFM here stands for "Wideband FM", which is typically used by commercial broadcast radio.)
