Hi Linda and Others,

If the so-called knocking sound is repetitive, I wonder if you have a 
radio scanner near by your ham equipment.  In the old days, the scanning 
process would mix with the oscillator of the ham equipment and on some 
frequencies you would hear a repetitive thump, thump, thump as the 
scanner passed a particular frequency.
