[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 ...

A sensitive and reliable rf field strength meter is an invaluable instrument in amateur radio ... the measurement can be done without using a stronger carrier signal and most of the radio controllers ...

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 at 315 MHz or 433.2 MHz.

It’s not so far-fetched though, while bugs and hidden cameras in for example an Airbnb may not have flashing LEDs, they still emit RF and can be detected with a signal strength meter.

The UBA 9290 battery-operated field-strength analyzer from AWT Global covers a frequency range from 100 kHz to 2.9 GHz with a sensitivity of –117 dBm to evaluate even weak RF signals. The handheld ...

Fig. 2 shows the equipment in detail: The RCA Type 301-B field strength meter contained a step attenuator, tunable band pass filter, RF amplifier and detector/filter, which produced a DC output ...

A digital television strength meter connected inline with the ... port on the meter -- typically labeled "TV" or "RF." If you receive your TV signal via satellite dish, connect the end of the ...

The FCC-prescribed method of using a 9-meter mast, a tuned horizontal dipole and a 30 ... Audemat-Aztec combined a complete FM broadcast receiver package that includes RF signal strength, FM stereo, ...
