thank you
glad to hear it helped
resistor R1 is not indicated on the diagram. (the lamp)
yes the Lamp acts as a variable resistor
What is RF supposed to be?
I used RF or Rf to denote the feedback resistor.
For high frequency (50-80MHz) which colpitt oscillator will be best?
You can use colpitts or hartley oscillator for that range of frequency
yes true
