Hi All 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 http://youtu.be/QYYnAz73ZCw Any link or advice are welcome Thanks 73's Nader/st2nh http://st2nh-blogger.blogspot.com/
