Choke & Transformer Power Ratings - Palomar Engineers®

The question: “what power rating do I need for the choke or impedance transformer for my station? is asked many times and the answer is usually the same: “It depend on you transmission mode, frequency, impedance ratio, duty cycle, and load impedance. (Note: FT8 mode update – see below). This page attempts to clarify some […]
