Abstract
We started this project for building affordable radio astronomy equipment for people to experiment in a professional way. The same equipment and techniques are used in real-world systems, including wireless communication, radar, and satellite technology. We built a system, which was simple and efficient, but the amplifier we selected was no longer produced. Now we are testing out a new amplifier to compare the performance to the old. The gain of the amplifier and bandpass of the filter was comparable to the original device. Next, we are testing for external interference with a handheld RF signal generator. This experiment is important because it provided evidence on how new amplifiers work compared to the old ones.
