Hello,
from last years ago i try looking to 20m oscillator from little available components with high performance and stable frequency & can tuned.
so this is my full design & tested . i call it TXR Oscillator Design.
it's take from me 2 weeks to design & more than 70 experiments in other 10 days but hi hi cost me some parts from my electronics junk box!
i build this design and it's great work for me & i tuned it on 14.290 with 100% perfect results.
but all the ways if your want make some experiments i Recommended by the:
-total C13 ,14 from 350 pf to 370 pf for best optimum output... but check Commercial values are available
-R8 value 1k
- R9 value from 100 ohm to 10k .... i hope try 450 or 550 ohm soon
-R7 some friend try change it for output level
