| - | ====== Scout QRP Mod ====== | ||
| - | Here is the method that I have used with great success to easily modify my two Scouts for instant QRP/QRO operation. | ||
| - | |||
| - | * Remove the bottom cover of the Scout. | ||
| - | |||
| - | * Locate the power control potentiometer (there is a hole for it in the bottom cover). | ||
| - | |||
| - | * Locate the wiper of the pot. | ||
| - | |||
| - | * Carefully solder a small diameter wire to the wiper at the board. | ||
| - | |||
| - | * Solder a 390 Ohm resistor to one terminal of a minature SDST switch. | ||
| - | |||
| - | * Solder the end of the wire to the other end of the resistor. | ||
| - | |||
| - | * Connect the other lead of the switch through another small wire to a convenient ground. | ||
| - | |||
| - | Electrically that is all it takes. I set my power pot. to give me 40 Watts in the high power position, when I throw the switch in the other direction I get 4 Watts. | ||
| - | |||
| - | Finding a place to mount the switch is tight. I found just enough room by centering a 1/4 inch hole (use a pilot drill first) on the "KEY" marking on the rear panel. That puts the switch close to the inside edge of the chassis. | ||
