This circuit was found on an 80's Ham Radio. The transistor admits equivalent. The circuit can generate 20 to 100 MHz signals operating at the fifth harmonic of the crystal.
With the use of a very sensitive and lockable relay this circuit can be used in intervals of 15 to...
We found this circuit in the 1982 SGS Linear Integrated Circuits manual. The transistor supports...
This circuit generates trains of pulses in regular intervals determined by R1 and C1. The...
