Maybe this should be a poll, but then not everyone uses code these days. What's your preferred CW frequency on receive?

Because my binaural CW filter has a center frequency of 720Hz that's what I have grown used to, others prefer a lower frequency and the filters on our club rig  seem to peak at about 650Hz.

So, for a nice comfortable ragchew what frequency of CW do you use?

I use 500-600 Hz.  I adjust this all the time, so it's not preset to anything in particular.

I like 550Hz.  The lower tone sounds better to my ears than the higher tone, as I have some high frequency loss.  Another good thing about my hearing loss is that I can't hear my xyl complain as well as I used to, hi!

I have mine set at 600Hz.  I can adjust my filters, too, so I set them to have 600Hz in the center.  It seems to be a pretty good frequency for my rig's speaker and my headphones.

This is an interesting topic for me.  I've seen some discussion of this in the past on the Ten Tec reflector.

My own preference is in the range 400 to 550 Hz.  I know one top notch lowband DX'er who prefers 250 to 450 Hz for weak signal work.  

I think the low pitches are advantageous also in heavy QRM situations (such as picking a callsign from a pileup).  For example a 20 Hz difference between two signals corresponds to a 5% difference at 400 Hz, but only a 2.5% difference at 800 Hz.  

Many of the modern transceivers (including my Omni 6) don't allow for much experimentation below 400 Hz or so.  I'm told the TS-930S was an exception.

My preferred CW frequency is 7040 kHz
I also like 10109 kHz  My sidetone at
600 Hz matches the tx offset to zero beat
My rig is an Icom IC-706mkiiG with 500 Hz
and 250 Hz crystal filters installed.
