A while ago, one station in a contest had a 20 KHz wide signal. I send him
email and he replied that he had K3.

Yesterday I was calling D2EB on 3521 and got lots of angry reports about my
signal jamming everything around.  One station sent a panadapter screen.
There are spurs about every 700 Hz. The first one is -15db from the main
signal, the second -25db, and 3 KHz away it is -35 db.  

I checked the radio later with a SDR. It had spurs but not as big. I checked
the radio today, and the spurs seem almost gone. 

My K3 is #2283.
