Re: No RF out but signal heard on nearby receiver

The gate drive is too low. I remember it being much much higher.

I suspect one of the trifilar toroids has a short and this will show up if you move them. I personally saw this issue in a defective board Farhan gave me. I just moved the leads till the short went away and blobbed some hot glue to keep the wires apart. Also see that your audio drive is at least 150mv p-p or more. Raj On a scope, p-p voltage at the gate of Q15 with a 1000hz tone: 40mv with no RF out and 200mv after Q13 replacement |
