I had some strange noises comming from a FT-900/Astron combination.
Called Yaesu tech support. Was advised that Astron had a service
bulletin out on their supplies. It deals with RF currents
circulating around on the case. I ended up opening up the supply and
placing a grounding strap from the case to the negative post.
Problems went away. Suggest you check your supply for this strap.
