You can also use the AFV/dBV function in the K3, see Owner's Manual for 
details on how to use.

Why wouldn't Spectrogram show you that?  Real time right on your 
computer, and it's free.

[Elecraft] K3: RF in compared to AF out, in dB?

2011-07-16 Thread John Harper
Does anyone know if any charts or graphs exist online that illustrate the 
effect of IF bandwidth at the audio stage?

I know Clifton Labs compares various IF bandwidths with different roofing 
filters - I'm looking for a visual representation of audio output vs. RF freq 
in order to get an idea of how quickly (in dB) the audio gets attenuated as you 
tune away from zero beat, for a given bandwidth...say, 150Hz dialed in.

Thanks,
