Hi , it is illegal to use a modulated oscillator below about 2 meters. It will work but adds FM even to a crystal oscillator. In fact commercial vhf equipment using crystals actually phase modulate the crystal oscillator to get FM. They of course go through several multiplications to get the plus and minus 5 kc deviation.. That's kHz for youngsters!.. The rules simply state NO!..hope this helps..
