You will need to modify the coil shown to use it with the regenerative receiver. Place a single layer of electrical tape around the bottom winding of the coil (L1); wind 6 turns of 19- or 20-gauge wire over the taped winding, leaving 4 pigtails. Tape the winding in place. Then connect the modified coil to the receiver circuit as shown in the figure. The two 2N3904 transistors are connected in a Darlington high-input-impedance circuit configuration to reduce loading of the tuned circuit. Potentiometer R2 controls the positive RE feedback. If the receiver seems dead or if only weak signals are heard, try reversing the leads on the six-turn feedback coil.
