this circuit by g3esp was in sprat 95. the two crystals (17642 and 14060 mhz) oscillate at the same time, giving a resultant frequency of 3.509 - 3.587 mhz. the output is taken from the emitter and should pass to a suitable band pass filter.
c 1,2 & 3 are plystyrene
l = 44 turns enamelled copper wire (0.4mm) on a t68-6 toroid.
