$10 Receiver has MicroVolt Sensitivity: 08/18/94 EDN-Design Ideas /
(Electronic Circuit diagram added 03/03) The three-transistor circuit in Fig 1 costs
less than $10 to build, uses commonly available components, and consumes less than 10
mA from a single 9V battery. If you wind coil L1, as the figure shows, the circuit
receives signals in the 5- to 15-MHz short-wave band. You can add turns to or subtract
turns from L(or change C2) to receive other frequencies.... |

45-860MHz Radio receiver Based on UV916-tuner: This receiver use a TV-tuner,
a simple radio-circuit and a interface to a computer. The computer control (set)
the receiving frequency from 45-860MHz. The purpose of this project is to learn about
tuners, it's a pre-project for my Spectrum analyzer project. The UV916 or UV918 tuner
is easy to find in broke TV or VCR:s. It is a common tuner... (Electronic

49MHz Walkie Talkie: Lots of people are requesting walkie-talkie and RF
remote control schematics, so here is some. Building these circuits needs special
equipment and expertise in RF circuits. If you are going to experiment with these
circuits, please note that I did not build them, and I am not able to help you with
any details. If you have no experience in RF, I suggest that you choose the easy way
and buy a ready-made RF module. Otherwise you can realize you have an exact copy of a
circuit in your hand, still it doesn't work the way it should. (added 8/03) |
