There are two common causes of this problem. One is the
potential difference between the two radios. Bonding and
using
the same outlet will fix that.
The second common cause is a magnetic field that couples
into
the loop between the two radios and the DXDoubler. That
field is

You mention bonding in vehicles and this rang a large bell with me: all
military vehicles, land sea and air, require a separate dc return other than
the chassis for the battery negative terminal. Filter caps for emc are
returned to the chassis of the equipment which is strongly bonded to

Just completed my second K3/100 and am in the process of integrating them
into the former FT-1000 SO2R station. I'm using the DX Doubler for SO2R
switching. I bought the K3 cables from them, and hooked up both radios to
DXD. When I plug the headset into the DXD phone socket, I hear a hummy

Would bonding the two chassis together with thick wire or braid work?
