Hi Larry,
                Yes it occurs on all HF receivers.
                It occurs on all antennas.
                Does not occur with antennas disconnected.
                Does occur on an HF mobile when I drive away.
                It is a carrier, wide band I would say. Almost like a 
buzzing sound.
                It is there about 80% of the time.
                Signal strength is constant when there.
                It is the strongest to the east of me.
                There are houses, a gas station, and Wal-Mart to the 
east/southeast of me.

                                    Thanks for asking the questions. Helped 
me explain it hopefully better.   73 John
