I DEFAULT to “AM” so make sure you choose “LSB” on the lower bands and “USB” for higher bands when listening to Amateur Radio frequencies. (Or CW if hearing morse code! And FM for 2 meter band!). If listening to any signal and you hear a continuous tone, try using the “Autonotch” setting. Finally, use the wider and narrower bandwidth controls to eliminate neighboring conversations.
AM, LSB, USB, FM are all different forms of modulation. If you are listening to a station modulating in USB and trying to demodulate it using LSB it’s going to sound really weird. If you’re getting started in amateur radio, it’s should be on your high priority list to understand these modes! Sidebands are a fundamental concept in radio.
