Koulye a, manje siyal la pwodiksyon nan Gwoup C rive nan filtè pas ki ba te fè nan seri de Kondansateur ak endukteur. Sa a se fè reyalize pi ba Harmony galo nan pwodiksyon an anvan manje li nan antèn la. Mwen gen te ajoute yon endikatè ki ap dirije D3 ki montre ke w ap transmèt ak tout bagay ap travay amann. Si ki ap dirije a pa limyè moute Lè sa a, yon bagay ki mal ak schematic la. Pwoblèm nan fèt anjeneral nan pati a osilator (jis pou yon allusion). Epitou mwen jere yo retire prèske tout kondansateur varyab men se yon sèl la pou akor a, paske schematic orijinal la te gen kondansateur plis varyab yon anpil ak li difisil a ajiste yo tout.

Now feed the output signal from Class C to low pass filters made of series of Capacitors and Inductors. This is done to achieve lowest harmonics spurs at the output before feeding it to the antenna. I have added an indicator LED D3 which shows that you’re transmitting and everything is working fine. If the LED doesn’t light up then something is wrong with the schematic. The problem usually occurs in the oscillator part (just for a hint). Also I managed to remove almost all variable capacitors but the one for the tuning, because the original schematic had a lot more variable capacitors and it’s hard to tweak them all.
