I spent years, lots of effort, and lots of money trying to mitigate
amplifier fan noise. Many kinds of noise cancelling headphones failed,
including one aircraft type. I even tried putting an early NC headset
inside of a pair of earmuff type ear protectors. I built a cabinet to
enclose the amplifiers, but IT's fan was noisier than the amplifiers.
Finally bought a passive Radiosport headset. By far the best, though I
still think putting the KPA1500 in the other room would be better. As
soon as the remote software is available.

So here I am with three hours to wait until my plane boards. I tried a set
of Bluetooth Sony noise cancelling headphones. Big mistake. They're
great.
$300.00 is too much for me. What other models are in use with Elecraft
folks?
