Dr. Samuel Ritchie (EI9 FZB)
List of things I am working on, going to work on, half built, put aside in frustration, do not understand yet, aspirational, etc.
-
R&S dual loop antenna - up and running, need time to document.
-
Playing with power supplies without going near 220 Volts - two PCBs done, 3rd PCB in design, need to assemble, measure, correct my mistakes/misunderstandings and then write things up.
-
Evaluating a number of RF circuits using modern IC's - PCB done, components are in my hand, might be winter 2023 before I get to work on this.
