[Elecraft] Scanning and channel hopping question...

[WD4SDC]

Hi All,

I've been gathering information on the scanning feature of the KX3 (not an
owner......yet - VERY tempting).
I have the basics - VFO scan, channel hopping, live scan, muted scan, the
rules for channel hopping.
I found this:

"Scanning while muted (normal scanning mode)
allows the K3 to ignore stable carriers, unmuting
only when "interesting" signals are found."

...from the K3 manual - which appears to be a close DSP cousin to the KX3,
and I've also found some scattered bits about the KX3 that refers to
stopping when a "modulated signal" is found.  So, what exactly triggers a
stop scan?  It seems to be a bit more sophisticated then just an S meter
threshold - maybe using the AFV measurement?.  Is the scan signal detection
done after signal processing like noise blanking, noise reduction, notch,
etc?  That would make it REALLY good at scanning HF !

After scan stops on a signal, does it pause until the signal stops, or does
it continue after some fixed time?

What is the scan (hopping) rate.  I see that in VFO scan you can make it
effectively slow or fast by changing the increment step - , but in channel
hop, the "increment" is one hop - just not clear on the hops per second.

And finally....how does the scanning stop/resume sequence work?
When a signal is detected, the scanning pauses for some interval, then
resumes when the signal stops? Or after a time interval if the signal is
still there it continues scanning until it hits the active channel again?

I know these are very narrow questions about a radio that has a LOT of
capabilities, and maybe I'm the only guy that wants to know this....but at
least if I ask it here, then the one other person that may be looking will
find it here;)  I've used (channel) scanning on HF quite a bit.  Very useful
now that VFOs are rock solid and tune in milliseconds. 

Thanks to all on the site for LOTS of other very useful
questions/answers/ideas.
