If you're inclined to use a rig control program, DXLab's Commander now has
very nice slider controls for adjusting the K3's bandwidth and shift.
It only
takes a click of the mouse to change between 10 Hz and 50 Hz increments.
(DXLab is free!)

The 10 Hz/50 Hz radio button in DXLab's Commander does not
change the operation of the radio. It only changes the steps
used by Commander.

Thanks for that correction, Joe. However, I think-- as far as the user
is concerned-- the
effect is the same, i.e., with Commander, one can very conveniently
increment the shift in
increments of 50 or 10 Hz as he/she chooses. It works great!

The only problem is that 10Hz steps limit the range of Fc ...
when Wayne eliminates or relaxes the restriction, you will be
correct as far as operation with Commander is concerned. Now,
If Wayne would add a "set" command to allow direct access to
10/50 Hz, perhaps we could convince Dave to link the radio
button to it <G>.

Re: Elecraft] K3 PB Ctrl Shift .01/.05

The bandwidth appears to be limited when using 10 hz and it is painfully
slow when the bandwidth is fairly wide.

When I am in PSK or RTTY and using search and pounce, I use wide bandwidth
in HRD and DM780 to find the signal I want on the screen and then narrow it
in so it is better for me to have 50 when wide and then 10 when much
narrower so I wind up switching all the time.

What would be really nice, if possible, is to auto change to 10 hz shift
when you adjust your width below (pick a number) 200 or so and back when
you go above that width (optionally?).

(A single button would work too, guess I will have to figure out how to do
that.)

Thanks es 73, de Jim KG0KP

1. It is not the bandwidth that is limited, it is the range of the SHIFT
control. For example, in DATA A, the bandwidth can be adjusted all the
way up to 4 kHz, no differently from PB CTRL = 50 Hz. What is different
is that the range of adjustment of the SHIFT control is limited to the
range 1280 - 1720 Hz. As you noted, if the range were wider it would be
painfully slow to adjust it more broadly anyway.

The best solution to this is what some software calls an ALIGN or OPT
function. This works as follows: with a wide filter, find the signal you
want by clicking on it in the waterfall; click on the ALIGN or OPT
button which retunes your radio so that the signal you have selected is
now on the optimal frequency (FC = 1500 Hz is the obvious choice in DATA
A); and now adjust the filter bandwidth as narrow as you like. I do not
know whether DM780 has such a function, but if it does, that would be
much easier than using the SHIFT knob to chase stations up and down the
waterfall.

2. If an automatic switch between 10 Hz and 50 Hz shift resolution with
filter bandwidth is ever implemented, I would suggest that it kick in
somewhere around 400-500 Hz, certainly not as narrow as 200 Hz. In RTTY,
the widths where the 10 Hz shift resolution is most useful are those
where the skirts of the filter and the skirts of the RTTY signal
overlap. At a shift resolution of 50 Hz and with some choices of PITCH,
this overlap could happen at filter bandwidths up to 350-400 Hz.

DM780 has the center function and it works fine so I dont miss any
manual shift functions.

I have defined the following two macros:

#++
# Center & narrow macro
# {{RADIO-CONTROL
#
# This macro only contains commands for tuning your radio.
# The text is not added to the input (TX) window.
#
#--

center-on 1500

Set slider-pos K3 Filter~Width 30 // Filter Width = 300Hz

#++
# Wide macro
# {{RADIO-CONTROL
#
# This macro only contains commands for tuning your radio.
# The text is not added to the input (TX) window.
#
#--

Set slider-pos K3 Filter~Width 400 // Filter Width = 4000Hz

I have set the 250Hz filter to kick in at 300Hz.
