I have only seen this problem with one 1W40...so far. The 1W40 BFO circuit (U5) has a low-Q design for the crystal oscillator X6. "IF" you find that U5/X6 does not oscillate, the fix is to add a resistor from PIN-7 of U5 to ground. This increases the current through the oscillator transistor in U5 and increases it's gain to help start the oscillator. The symptom of this problem is the following: 1. Touching pin 1 of U5 produces audio noise in the audio output. 2. Touching the hot end of C32/X5 produces no noise; no signals can be heard from the receiver because the BFO is not functioning. Solution: Solder a 15K or 16K or 18K or 22K on the bottom of the PCB from PIN-7 of U5 to PIN-3 of U5. If you have the above problem and do not have a resistor, I can mail you one. ========================================================= *** = BAND SPECIFIC COMPONENT ===================== End of List =======================
