Assemble by soldering the components to the pads indicated. Keep coil, resistor and capacitor leads as short aspossible. The coils should be 3/16"-1/4" above the board and separate turns by one wire diamter, bend lead to form a little mounting foot for soldering to the circuit boar. Tuning & power output are affected by the distancebetween the coil turns, you can make fine adjustments by either spreading or compressing the coil slightly.The area surrounding the pads is ground, C2, C3,C4 & C6-C10, L2 and R1 are soldered at one end to groundas well as the shield braid on the coax cables. Bolt Q1 to a small heat sink or the chassis with heat sink thermalcompound or gray thermal pad underneath the tab. With an input level of 200-500 mw you should see an ouputof 5-6 watts. Be sure to have a proper dummy load (50 ohms) or tuned antenna connected to the output, doingotherwise will likely destroy the transistor.
