Micrófono Inalámbrico por FM

Este micrófono tiene una muy buena estabilidad de frecuencia, aproximadamente 1Km de alcance (en condiciones ideales) y tiene excelente sensibilidad de audio. Todo esto se logró agregando un amplificador de RF (con 10dB de ganancia) y un pre de AF que refuerza la modulación a su punto ideal. 142fc496eac1104b24ae30fdcb1cffa1 Es muy fácil de construir. L1 está formada por 3. 25 vueltas en espiral, que forman parte del dibujo.......

Experiment 2 Revisited

Camp ended on Friday -- 21 campers went home happy with a fully-functional Arduino-powered robot. I'll post some photos and thoughts on the camp in another post, but today. . . back to Make: More Electronics!Back in Chapter 2, Charles shows how he connected up two analog gauges to record milliamps and microamps, and that's exactly what I've done. Look carefully on the back of t.......

75 Meter SSB Transceiver

Here's 75 Meter QRP SSB Transceiver. In general, the transceiver switches the 4-element 1500 ohm xtal BPF ends between the inputs and outputs of the two SA602s to reverse the signal flow for R/T operation. Since no IF amplifier is used in the design, 20 dB of additional receiver gain is produced by the 2N2222 receiver RF amplifier, while automatic gain control (AGC) is produced by the peak DC swing of the LM386 output passed through a rectifier and filtered by a capacitor and fed to the gate of .......
