NE612 bat receiver The echolocation of bats has grown to a field of science since its detection and much is still being discovered. I've built several receivers using the NE602/NE612 chip. My first look at the SDR technology was not very impressive - FlexRadio SDR-1000 was too complicated to build and too expensive to buy, but second one - SoftRock was another story: simple, clear principles and easy to build. That allows an inexpensive 6-MHz crystal to be used. It can handle signal frequencies up to 500 MHz and local oscillator frequencies up to 200 MHz. The LM386 is a more easily obtainable part (available at most Radio-Shack stores) than the LM380N-8. Das Empfangssignal gelangt über den Hochpass L2,C5,L1 und C4 auf den Eingang von IC1.
