Cb Signal Generator
Do you know a signal injector circuit? If you are an electronic technician amateur in repairing of television or radio receivers. He said he is made a signal injector circuit to detect the signal in various sectors.

For example: in the sector amplifier, when the input signal of this circuit, if the amplifier is good, we can hear the sound from the speakers. Or we can check signal the following points by the oscilloscope more easily. Or we will apply to check the vertical yoke driver of the TV, too.

The modulating signal may be used as an audio source. Most signal generators allow external or internal modulation. RF leakage is generally very low, and can bechecked by terminating the output in 50 ohms, placing a receiver with ashort wire antenna nearby and attempting to pick up the generator's signal. You need a Cheap CB radio, A linear amp, and a bottom loaded CB antenna (easier to build a ground plane for it). In my case I ran a continuous 6khz tone from a signal generator which was more.
We have two circuits for you to try to make them below.
1. Simple Signal injector circuits
When see in simple signal injector circuit as shown figure this below, he used two transistors join together to be astable multivibrator which has a signal output frequency of 1,000Hz in square waveform.
A power supply voltage of this circuit is 1V to 5V. We recommend a AAA 1.5V-battery, it makes a level amplitude voltage peak at the output lower than 1Vp-p. Thus, the circuit is safe.
The creation of this circuit is simply only composted all parts of the perforated board.
The schematic of this projects is easy!
