I know many users are happy with the 700 Hz roofing filter you guys have had custom-made. However, I am wondering just how helpful it actually is, compared to other, more standard roofing filter BWs. If a 700 Hz bandwidth is "ideal for scanning", just how is a roofing filter needed when scanning? By definition, when scanning, one is tuning across a band, looking for a signal of interest. Is a medium-narrow roofing filter really helpful in this case? Does it make scanning more productive than say, a 1 KHz filter?
I am not trying to be argumentative, just trying to understand how a roofing filter of this width may be (more) useful (than other choices) in a radio like the K3 with continuously variable final DSP filtering.
