Greg Manfroi of WIUM/WIUW, Western Illinois University, Macomb, IL, sent us this idea on a construction method for the shielded-loop AM antenna. Start with the electrical specifications as described ...

SIMPLE, EASY-TO-USE FM/AM RADIO WITH HIGH QUALITY SOUND: Portable handheld radio with digital tuner has a simple, easy-to-use interface, with antennas that pick up both AM and FM signals EASY-TO-SEE ...

Comprod Communications Ltd. offers one of the only full band 136-174 MHz disguise AM/FM antennas in the world at 1.5 VSWR throughout the entire band. Comprod antennas are indistinguishable from the ...

This simple little circuit can be used for AM, FM, and Shortwave(SW). On the shortwave band this active antenna is comparable to a 20 to 30 foot wire antenna. It is further more designed to be used on ...

While we can’t argue that FM has superior audio quality and digital streaming allows even higher quality in addition to worldwide access, there’s still something magic about hearing a weak and fading ...

Integrating an antenna input and an audio output in a monolithic IC, the Si473x AM/FM-radio-receiver family requires no manual alignment. Requiring two external components in a 0.15×0.15-cm board, the ...

AM reception can be very difficult because of the inherent succeptibility AM has to electrical noise and other sources of interference. The built-in antenna in most receivers – a coil and a ferrite ...
