Audio wiring makes a very good HF antenna...still, the CW signal has to
beat against something for RF noise to appear in the speakers. RF alone
won't do it. Roger didn't say, but his speakers are probably internally
amplified, which would address the noise factor. I know that turning off
my computer speakers makes the noise go away.
