#228 In this video I continue looking at cavity filters by performing some experiments on a set of practical builds. I start with a single resonator single port cavity just to confirm the simulation results; but from there I move onto a set of practical filter, looking at the construction methods that I used, the tools used for dimensioning and finally a look at the filters response.
