Notes
L1 and L2 are 5 turns of 28 AWG enamel coated magnet wire wound with a inside diameter of about 4mm. The inside of a ballpoint pen works well (the plastic tubę that holds the ink). Remove the form after winding then install the coil on the Circuit board, being careful not to bend it.
C5 is used fortuning. This transmitter operates on the normal broadcast frequencies (88-108MHZ).
Q1 and Q2 can also be 2N3904 or something similar.
You can use 1/4 W resistors mounted vertically instead of 1/8 W resistors.
You may want to bypass the battery with a .01 uf capacitor.
An antenna may not be required for operation.
A thanks goes out to Mike_Springer@iname.com for cleaning up the original image once displayed on the page. It looks a lot better nowi
