I run this for my Citizen Skymaster on a picoPi. It works. Being within receiving distance of JJY in Yokohama IETF, and in Frankfurt near the german transmitter was wonderful, but I have an NTP synced dummy at home with a copper loop antenna and it works fine.
Using the HDMI lead interferes with the rPi GPIO signal being used to supermodulate the RF. As long as you don't drive the HDMI, its fine. I think its possible HDMI is an RF radiator.
The java/javascript trick with headphones works too.
