You can also use the AFV/dBV function in the K3, see Owner's Manual for details on how to use. 73, Lyle KK7P >> Does anyone know if any charts or graphs exist online that illustrate the >> effect of IF bandwidth at the audio stage? __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html

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?
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.
