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.
DM780 has the center function and it works fine so I dont miss any
manual shift functions.
I have defined the following two macros:

Set slider-pos K3 Filter~Width 400// Filter Width = 4000Hz
I have set the 250Hz filter to kick in at 300Hz.

Re: [Elecraft] 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.)

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?). 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. 73, Rich VE3KI __ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
