I consistently get a low freq. audio hum in MW AM broadcast. It makes reception in this band a curiosity, not something I can really listen to.
Since users are consistently raving about the audio quality in this band, I guess I'm doing something wrong. Any sort of troubleshooting advice? I use a linear lambda supply, not near the radio, and none of the cabling seems to be a problem. There is no hum in HF reception modes.
