Hi Dave, Without a saved CONFIG file, I don't think there is a way to retrieve the filter settings directly from the K3. Have you tried examining the filter settings for any information that is stored in a CONFIG file? The K3 Utility permits viewing and editing stored crystal filter settings.
You could try to visually inspect the filter bandwidths using an audio spectrum analysis tool, but you would have to turn off any DSP filtering to see the actual IF crystal filter response at audio frequencies. With some effort you could distinguish 5-pole from 8-pole filters using the transition band slopes, but estimating -6 dB bandwidths should be more straightforward from the displayed spectrum. While a separate wideband noise generator would be the best source, you might have enough local wideband noise to obtain a reasonable spectrum depiction over the crystal filter response width. 73, Mike, K8CN ______________________________________________________________ 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 Message delivered to arch...@mail-archive.com
