I switched from USB to AM for a couple hours tonight while monitoring 
via spectrogram on 55.250 MHz just out of curiosity.  On USB, there 
were few.... but some.... meteors.  On AM I got zero meteors.  I'll 
leave it on AM overnight and see what it looks like in the morning, 
when the count is usually much higher.  But in my brief experiment so 
far, USB vastly outperforms AM when examining the results with a spectrogram.
