That's an interesting site. Does anyone know of a site that has
examples of signals at various SIO/SINPO ratings? I usually put down
some kind of rating in my logs, but I'm never sure if my idea of "barely
audible" is the same as anyone else's. It would be nice to have some
kind of example of various ratings from more experienced folks.
