I built the Kits and Parts RF Amplifier. Unfortunately it didn’t work.
When power is applied the meter in my bench power supply reads 0.01A. As soon as the Propeller beacon starts the current draw increases to 0.03A (at 8V). But the needle on my QRP power meter, which shows more than 25mW from the barefoot Propeller, doesn’t budge.
I don’t understand it. It’s a simple enough circuit, there isn’t anything to go wrong. Unfortunately I find these kit construction failures too demoralizing. I struggle with my vision and shaky hands just to build the board. Desoldering and faultfinding are beyond me at the moment. If I do discover the cause of the problem it’s something really obvious that anyone with a normally functioning brain would spot. I think it is time for me to accept my limitations and stop attempting to do what I used to be able to do before my brain surgery. From now on if I can’t buy what I want ready to go out of the box I’ll just have to do without.
