Found in an Electronic Design of 1964, this circuit is intended to the signal amplification in the 88 to 108 MHz band. The transistor can be a modern equivalent.
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...
