100 MHz RF Detector. This circuit is capable of detecting signals up to 100 MHz, depending on the value of L1. Use a 100 µH choke for signals between 30 and 100 MHz, a 1000 µH choke for frequencies between 2 and 30 MHz, and a 2.5 µH choke for signals below 3 MHz. In the circuit, the FET serves as a wideband amplifier. 0.The detector is built with minimal components, the central of which is the TI LM1458 dual op-amp with a handful of resistors and capacitors. There's no microcontroller, and nothing that would be recognizable as a radio receiver — the detector instead working on the principle of rectification.Starting out as a small TV repair business in 1948, Cobra Electronics Corporation continues to design and produce electronics products for consumers worldwide. Some Cobra products ...This means that the period of the wave is 4ms, or 0.004s, giving a frequency of (1/0.004) = 250Hz. If you change the timebase to 500µs (half of what it started at), you should see the waveform now takes 8 squares to complete one full oscillation. The period (and hence the frequency) remain constant because 8 times 500µs still equals 0.004s.Cons. No technology is infallible. And radio frequency analysers are no exception. Direction finders are only effective as part of an array and are incapable of detecting autonomous drones. Similarly, proprietary RF signal decoders are effectively blind to other models, as well as tampered or homemade drones.
