Grants Pass TV Repair | 2 Dollar Radiation Detector You Can Build. Beware of imitation diodes that don't have an H on them. @GrantsPassTVRepair | Uploaded 4 years ago | Updated 2 hours ago

In this video I demonstrate how you can build a simple Radio Frequency Detector using only a detector diode and an LED. This simple circuit was sensitive enough to operate from my cell phone, my WIFI router, my walkie talkies, my microwave, my smart meter, my google assistant, and any other devices with enough power that transmit in the frequency range of my resonant antennas.
Here is a warning about using some aftermarket diodes that may not work in this project. In this video I used the 1SS86 Diode which worked well, but beware that unless the diode is made by hitachi, it may not work on the higher frequencies. Thanks to a viewer I've also learned that the 1N5711 also works.
