[Elecraft] kx1 audio filter

[Hrafnkell Eiriksson]

Hi

I was just checking up the audio filter bandwidth and attenuation when
changing the bandwidth on my KX1. I used the NGEN noise generator and
fed the audio output to my soundcard and analyzed with Spectrogram.

The bandwidth changes what seems to be correct when I change the
filter from wide to narrow but the output level drops over 10dB. Is
that normal?'

I assume this list doesn't accept attachment so I've put the
screenshots of my spectrogram display up at
