Here on Guam we are plagued by very high noise levels across the entire 10m band. This is due to illegal radio users in Southeast Asia – taxi drivers and others – who use this frequency spectrum. The result is unavoidable QRM across the entire band that is often S9+20db or more. It makes copy of weak stations impossible. Below is a link to a MP3 I made, listening in the 10m band, USB mode, on a single frequency.
