Hello everyone,
I'm interested to know in which software emulator I can repeat this scheme?
what type of generation does this electronic circuit belong to,
what type of inductors, they are in the form of a black coil with a rectangular core, what is in the photo?
due to which elements the frequency is generated at 1.7 MHz,
what can be changed in the circuit to increase the adjustment, now when I turn to the maximum variable resistor R505, the frequency is 1.735 MHz,
how to increase the adjustment range, for example from 1.650 to 1.735 MHz
Thank you.
