[Yaesu] Re: YAESU & ASTRON POWER SUPPLIES

[Dave Maley]

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.
