Priced at only $80, the portable RF Meter is a low-cost signal-strength measurement tool for designers of RF radio systems. Two models are available to detect signals ...

The circuit was designed to measure the electric field strength in radio frequency band where it can be applied during the modulation of AM and FM signals in the VHF range. Field Strength – the ...

The author is senior technologist at NPR Labs in Washington. Field strength measurements are almost as old as radio itself, as engineers have endeavored to test and improve their RF transmission ...

This simple circuit measures the strength of a radiated signal from a transmitter. It is commonly used by model airplane builders to check whether their transmitter are really transmitting the radio ...

[Scott] wrote in to us with his simple, but well done RF signal strength meter. As he points out in his post, sometimes an Arduino is overkill, so a Picaxe 08M was used instead. Apparently this was a ...

(Phys.org)—A team of researchers with the Center of Planetary Science (CPS) has finally solved the mystery of the "Wow!" signal from 1977. It was a comet, they report, one that that was unknown at the ...
