SDR applications: Ways to use the RF “Swiss Army Knife” – Jack Spitznagel KD4IZ
It is common knowledge that SDR devices make interesting and economical receivers and transceivers, but what else are they really good for? I will describe several of the many alternative uses for the spectrum scope and waterfall diagrams that are provided by SDR software. You will find these uses will help you to better understand what a poorly configured transmitter, the ionosphere, and QRM can do to signal quality and readability. Hopefully these bonus uses will help make you a better operator.
