This circuit, which appears elsewhere in this section, was taken from McGRAW documentation from the 1990s. The circuit supports any MOSFET according to the motor current.
We found this oscillator in a documentation for radio amateurs from the 1970s. The circuit can use...
Many oscilloscopes have high impedance inputs that make it difficult to observe high frequency signals...
This is the receiver for the previous circuit we found in the December 1992 Radio Electronics...
