6 khz cw question

N4LQ-2
I understand how to use the menus. Let me restate.
 The problem is....When you do have the 6 khz filter engaged for cw, your
DSP filter won't go wider than 2.8 therefore you can't listen to 6 khz
bandwidth. What's up with that? It works find in SSB mode but not CW..

Right now, I believe that the firmware does not allow the CW bandwidth
to exceed 2.8 KHz in RX. This may be changed in future firmware upgrades.

Surely no one would want to listen to a pitch as shrill as that given
by a signal farther than 2.8 KHz from the BFO, or to a signal on the
other side or zero beat, depending on how the passband was shifted.
I'd find it rather irritating.

Re: 6 khz cw question

Oh yes...I want to hear as much bandwidth as possible partly because it's my
temporary cure for no bandscope and partly because I just like a wide open
sound when working around the shack. The sound of QRN and all the cw signals
is more relaxing than listening anything I know of, shrill pitches included!
I see no reason for Elecraft to have deliberately restricted the bandwidth
in CW mode only.

Not just cw Steve - ssb rx bandwidth adjustment is currently restricted to 4Khz max.

It's likely that these bandwidth restrictions will be opened up in future firmware (really).

I find the radio on a pleasure even though I pay no attention.  I use the K2
all  day long.  IF a cw sig pops up on right on freq., e.g., 7.035, then I
will work the station (if I can QRS to ~ 15 wpm).

Why do you want a 6kHz bandwidth in CW? Most of us would find listening to CW with a pitch of that pretty well impossible. Or maybe you are using it with your PC soundcard with programs like CW Skimmer? (of which I have strong views which I won't repeat here...). Here I never use a filter any wider than 400Hz on CW, except very occasionally 1kHz in contests so I here people calling off channel. In normal use there really is no need for anything wider.

Dave,

Listening 6 kHz wide is fine if you listen up to 3 kHz UP AND DOWN your
frequency. (So you might have a station on zero beat freq, who cares)
Being an ex R/O used to listening on 500 kHz, this was normal operation.

Why do you want a bandwidth of 2.7khz then? Most of us would also find
listening to CW with that pitch impossible or annoying. You're missing the
point here. We open up bandwidth so we can hear things. I would hate to tune
around the band with a 400Hz filter.
The point here is, a 6kHz crystal is install and selectable from the XFL
menu so why does it tandem the 2.8kHz DSP? That is simply a bug and
hopefully it will be fixed soon.
