You are free to select your transform size. For one project, I was monitoring the background noise floor across the HF band from 1 MHz... -
Paul Colby replied to the thread Undergrad How feasible is home radio astronomy?.Well, being serious about doing science and being interested in learning how things work by doing them really aren’t the same. I had...
