Crystal oscillator stage operating at 48-50 MHz puts out enough power to drive pair of triplers. All transistors are HEP-75.L1 is 20 turns No. 24 on 5-mm form, tapped 8 turns from cold end. L2 is 5 turns No. 20 airwound to 8-mm diameter. L3 is 3 turns No, 20 air-wound to 5-mm diameter, with center tap. rticle covers construction, adjustment, and uses,-B.
