https://stream.echo6.co/videos/watch/962d77d8-5e40-468a-9f2b-f0cd657f3899 If you're having trouble finding a 7.2 MHz ceramic resonator (though see the comment under an earlier video), a wide range variable crystal oscillator can do the job. This video describes the small modifications needed to make a wide range 'super VXO' for 7 MHz with a pulling range of over 50 kHz. The crystals needed - 7.122 & 7.159 MHz - are cheaply available as well. As with the first video you're encouraged to draw along for the circuit.
