True, Brian ..... For some QSK is an acquired operating taste. So can we get an option CONFIG:DUCKING ON/OFF But then we'll want a special 'beep' sound .... an option, of course CONFIG:QUACK ON/OFF 73 Hank K8DD ____________________________________________________________ GET FREE 5GB EMAIL - Check out spam free email with many cool features!

Yes, it makes sense. Next time I'm on the air,
I'm going to play with MON level a bit to see what I get with slight changes to
it's volume.

Then, when I zero the received signal, I tune it in to the point that it (audibly) "disappears" beneath the sidetone of the same frequency... if it's NOT zero beat, you'll be able to hear the offset. If it is zero beat, it'll be hiding behind the sidetone. I (think I) can provide a short WAV file to demonstrate if you have difficulty following the above verbal description. 73, Tom Hammond N0SS At 12:32 01/21/2009, Darwin, Keith wrote: Content-class: urn:content-classes:message _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.

I agree Kent,
I've also used that method on all my previous rigs. My preferred pitch is 700 Hz. The reason I use the CWT function on the K3 is not so much for the visual cw pitch indication, but rather for the rapid auto-spot/tune function. I find the K3 to be very consistent at quickly centering the CW signal, at my preferred sidetone pitch, in the selected passband of the receiver. Once auto-tuned I can quickly decrease the bandwidth to 100 Hz or 50 Hz and presto the signal is smack in the center of that very narrow passband. It's great for S&P with a wide passband (1.2 KHz), auto-spot/tune and a quick turn of the width control to 50 Hz bandwidth. The way Elecraft implemented the CWT function is fast, intuitive and repeatable. It's one of my favorite features in CW mode on the K3.

There is a third capability that many long-time CW operators intuitively possess. It is the immediate recognition of the correspondence of an incoming signal's pitch to that of the operator's longtime preferred sidetone pitch. Just as well known voices of loved ones and friends are instantly recognizable when their faces can't be seen, so also one's preferred sidetone pitch is likewise instantly recognizable when a signal is being tuned in and "hits" that pitch. This feature of the human brain requires no button pushes other than the initial setting of the sidetone pitch frequency. Once this is set, neither the SPOT nor CWT buttons need be used (on any rig). This "cerebral feature" is always there, regardless of the brand or model of rig being operated. Several of us used this capability on Straight Key Night when operating a friend's FT-2000 with it's myriad of buttons, switches, and multi-layered controls. Once we set the sidetone pitch to our individually preferred frequencies, zero-beating was intuitive. However, hearing impairment is a whole different issue and may well require the CWT visual aid. 73, Kent K9ZTV _______________________________________________ Elecraft mailing list Post to: [hidden email] You must be a subscriber to post to the list.
