Default Re: More Chinese AM radio kits

No, I haven't built this radio.
I've looked at the circuit and see one potential problem:
Compairing on-line datasheets for the 9018H transistor with the PCB legend I would suggest the transistor has reversed Collector/Emitter connections.
If the drawing of the components layout is shown topwise of course.
Much easier to see with the PCB in hand.
I suggest you check this out.
I haven't checked the other transistors but I wouldn't be surprised if they all have the same pin-out, i.e. all transistors are rotated 180-degrees out of order.
