Very strong signals are impossible to tune in well.
Reduce the setting of the internal RF Gain control.
CW signals wobble slightly if the receiver is bumped.
This is a normal characteristic for a simple oscillator. If the wobbling or instability is
extreme, toroid control L5 is installed too loosely and should be tightened up.
We have designed this book and the receiver itself to assure that you can build it
successfully and enjoy using it as soon as construction is completed. If, after building
your receiver, double-checking all assembly steps and going over the preceding trouble-
shooting suggestions, you and are still having a problem, please contact
