Modder builds realistic AM radio simulator to replace BMS flight sim's IVC voice chat

A developer working with BMS, a combat flight simulator, describes contributing accurate AM radio physics to a community-built replacement for the sim's existing voice chat program, IVC. The goal is to properly reproduce phenomena like AM radio's lack of a 'capture effect,' where two overlapping transmissions can both be partially heard, unlike the current IVC tool which reportedly just produces a generic noise when pilots talk over each other.

Retailers overstate range claims on digital TV antennas sold on Amazon

Digital TV antennas sold online, some marketed with claimed ranges up to 6,000 miles, cannot actually deliver anything close to that distance because of basic physics. Signal reception depends on a relatively clear line of sight to a broadcast transmitter, and Earth's curvature, along with buildings, hills and trees, limits how far a signal can realistically travel before dropping below the horizon.
