[Elecraft] [KX3] HS-5 'phones on KX3 & KX2

[Jay Rutherford]

Greetings,

When I listen to my KX2 and KX3 using the Kenwood HS-5 headphones, I hear a square wave-like buzz bilaterally. Active signals can push the buzz into the background, but the buzz is annoying when there is no signal. Listening to the KX radios on another set of headphones does not produce the same buzz.

Using the HS-5  'phones on my K2 or TS-2000 results in very pleasant audio.

Anybody have any thoughts why this might be happening?
