I am a beginner hobbyist form Brasil, posting here for the first time.
I am trying to understand the schematic of an old Transglobe radio that my late grandfather gave me. It motivates me to learn more of analog electronics. After searching the internet for oscillators, it appears to be something like a Colpitts Oscillator, but not quite.
If any of you could tell me what oscillator it is, it would be of great help.
The Signal comes from T101 and goes to T103, which is the mixer.
From what I understand T102 gives the gain to maintain the oscillation, but where is the Tank circuit?
Where is the feedback? C112 maybe? But from where does it come?
Why is t102's base a constant voltage?
Really appreciate any help! Sorry if it was too much of a beginner's question.
