After many projects on HF I'm looking for a simple VHF radio project!
I started by The Butler oscillator .
Tested on a breadboard .
Frequency stability is acceptable with this unshielded circuit.
The warm up drift in range of 100 - 200 Hz.then after it was stable with slight drift of 2 to 3 Hz.
No neutralized inductance use in parallel with the crystal.
Here is short video clip on you-tube
Any link or advice are welcome
