![]() ![]() ![]() The receiver will tune 3 KHz VLF through 2 MHz (120 meters) Ham, and the AM broadcast band: The chosen value of L1 and C1 sets the band received.ĬLICK HERE to watch a short video of the receiver receiving time signal station WWVB 60 KHz. The following diagram shows how to wire the unit to make a radio receiver having many features, including an analog signal strength meter. Input and output static and overload protected.Īudio output will drive any audio amplifier, and also will directly drive sensitive earphones. Works with the coil or loop antenna you supply, or works with our VLF ready-made antennas.Įasy 4 wire connection: Yellow = Antenna, Green = Audio Output, Red = (+), Black = (-). Lightning detector mode allows the receive to work as a lightning detector. The VLF-101 radio receiver does not have AGC so you get full dynamic signal range without clipping and faithful reproduction of signal strength levels. This miniature radio receiver module allows reception in the lower frequency bands up to 2 MHz.Ĭovers VLF 3 KHz to Ham 120 meters (1.8 - 2.0 MHz), and the AM broadcast band 530 KHz - 1710 KHz.įeatures built in RF signal strength meter driver to allow viewing signal strength with a meter, or for chart-recording signal strength over time. ![]()
