40M Cw Transmitter Circuit

Posted on Aug 16, 2012

This CW transmitter has an output of up to 3 W. By using 24 V on Q2, up to 10 W output can be obtained. If a 24-V supply is used, Ql must not see more than 12 V. Connect 12 V between junctions C3, R2 and L2, and remove L5. LI should be a low-Q 18- to 20- inductor.
