Description
Audible RF Field Strength Meter
A simple NE555P IC audible RF field strength meter ( vers. 2025 ). It can detect a 1W VHF / UHF handheld from about 2 or 5 meters away. A useful tool to have for testing radio gear. You will have to provide the external hardware. PCB Way will not provide these on the assembled version. More details in the Blog Article ( Coming Soon ).
