arrived a few minutes late Software - pointing the antenna - system performance - rf signal processing (too much information for doing in software?) - contact logging performnce measuerement, the receive sustem can be characterised by making measurements of noise levels while pointed at various known sources you can get a relative measure of if you are really receiving anything interesting. you can work out the system performance of the receiver by comparing with noise levels of give places over days when compared to other known systems.
