Rob,

I have a DX Doubler with a pair of K-3s and experienced the same problem you have noted. The fix is to go to the Top Ten website and build the audio isolator for each radio that is described. I believe that it is shown as an addendum.

If you can't locate it, let me know.

I built one and the hum disappeared.  Parts are inexpensive. I believe I go thte isolation transformers from Mouser.

73 and HNY,
