Hi,
today i have now exchanged all capacitors in the VFO and experimented with other transistors as well. The output signal of the VFO is not significantly stronger. No changes were made to the circuit itself at first.
Since I am not here for 2 weeks now, I will completely disassemble and reassemble the VFO afterwards. This seems more useful to me than soldering the VFO in the tight space available in the circuit.
Then I have to see how it goes on.

Wolfgang,
I keep being bothered by the fact that most, if not all, of the waveforms you show in your photos look correct, but just not the right amplitude.? Is it possible that your scope probe is faulty or that your scope is not calibrated?
Hope you are enjoying your time away from the bench.
