Das Konstrukt ist alles andere als stabil. Ohne Blechdose drum rum ist das teil auch handempfindlich. Sowas haben wir schon vor 50 Jahren als Schüler gebaut. Mit den damals verfügbaren Transistoren hatte das Teil ohne Nachverstärker 150m Reichweite, das Gleiche in die Dipoldose einer UKW Yagi Antenne verbaut machte 4-5km Reichweite. Der nachverstärker oder Pufferstufe muss vom Oszillator geschirmt werden sonst wird das noch unstabiler. Es gibt HF Gehäuse mit Trennblechen. Damit wäre es besser. Besser man baut den Oszillator als VCO und baut sich eine PLL dazu.

Diese Sorte Oszillator kenne ich auch als Bausatz in den 70-er Jahren mit nem 2N3553. Absolut unstabil und Hand-empfindlich. Es fehlen hier auch jegliche Abklatsch- Kondensatoren zwischen Ub und GND, ein Unding. Zudem ellenlange Drähte an den Kondensatoren - ist nicht gerade HF gerecht. Möchte nicht wissen, was hier auch an Ober- und Nebenwellen erzeugt wird.

Friend get some steel wool, then pour some hydrochloric acid on it until it dissolves completely and then pour some hydrogen peroxide (the formula is on the internet) to get your DIY ferric chloride 10% of the cost (note: make it outdoor), if you are interested i can tell you how to make professional thermal paste and your own high quality flux and soldering paste 🙂
