When and for what is it important to have a good quality clock on your SDR for amateur radio astronomy?
Most natural sources are broadband, so unless you are doing inerferometry, for total power radiometry, clock quality is not important, anything will do. For hydrogen line and similar work, a…
Has anyone designed dishes where the the surface is not parabolic but instead a complicated curve?
Yes. In fact, some of the most advanced radio and optical systems deliberately use surfaces that are not simple parabolas. Some examples: 1. Spherical reflectors A sphere is easier to…
