Part 15 AM and FM Station Operation / Questions about part 15 shortwave
« on: February 20, 2022, 0024 UTC »
I am interested in building a part 15 shortwave station. I would like to use the transmitter design in this video https://m.youtube.com/watch?v=4UGzL5FCcMM . I have a few questions about it. Is it possible to determine the power output, and how can I calculate how many microvolts/meter at 30 meters is it outputting? What antenna length is need to get 10000 microvolts/meter at 30 meters (the legal limit)? Approximately what is the range you can expect at 10000 microvolts/meter at 30 meters? I am going to use a 13.56 MHz crystal instead of 8 MHz. Correct me if 10000 microvolts/meter at 30 meters is not the correct limit in Canada.
