Topband: 160 pulsating noise

[wbcapps@mindspring.com (Bill Capps)]

hello
        sometimes when i listen to 80 meter cw, i hear a tone that is slowly
traveling across the band. i often monitor a frequency and i can hear the
tone travel right past my rigs vfo freq. i have often followed this tone by
slowly turning my VFO and staying right on top of it.  it is a strong sig
s-10 plus 
        i wished i knew more about radio to explain what i am hearing
