single transistor xtal osc

, K7ITM writes Hi Frank... Wow, the mixer in that circuit looks really weird. No, make it: that mixer looks WRONG. I would not expect single diodes to be directly across transformer windings like that. The mixer is indeed wrong. Only one diode is 'correct'. To correct the circuit, you could take D8 as the 'correct' diode. D6 - reverse. D5 - connect anode to D6 cathode. D7 - connect cathode to D6 anode. -- Ian |
