HI I moved C111 to the bottom of the board to allow room for a heat sink on Q6. I added more filtering to the power input line for better operation with weak batteries. In addition to the caps, I have an RF bead on the power in line that is hidden under the PCB. I changed C6 to 150 pf and C7 to 22 uf in reduce the audio bandwidth of U2. After all we only want to hear 700 hz. HI I used AADE filter program and changed the output PI network for a match of 80 ohms at collector of Q6 and antenna of 52 ohms. Not sure if it helps anything but thought Q6 might run cooler. Not verified. I used toroids in place of L2 and L3. I did make a mistake - I used a spring loaded switch and should have used a push button. Rock Mite puts out 800 mW with 13.8 vdc and one can hold your finger on Q6. de Stan Ak0b
