Default battery noise

In some cases, having a common ground (tie all negative leads together) will help. The ground must be a good rf ground though, i.e. a rather wide strip of copper braid etc. Just a single wire will not work as well although it might help. An old rule of thumb (quite a few years back when working in lots of radar and rf) the strap had to be 1/4 as wide as it was long. This is not practicle for many applications.
