Re: Terminating 3rd party app

Howdy Larry,

I don't believe that Launcher has the facility to terminate any programs other than the elements of the suite.

The only choice on the configuration menu tabs is for programs that get started before the DXLab parts and those programs that

will be started after the DXLab programs have been started.

Re: QSL queue Count Down after LoTW Upload (gets slower and slower)

+ AA6YQ comments below

Hi, I really like the adif file import after running a contest using N1MM and I have always wondered about the following behavior in DXKeeper... This is a minor issue / at the end of the day but on a larger upload to LoTW after importing a bunch of QSO's from an adif file, why after the upload completes does the count down of the QSO's that were queued up gets slower and slower as represented in the title bar of DXKeeper on the QSL tab? The first 100 QSO's counted down go pretty fast, but then you can see the update that is going on gets slower and slower... and if you are upload 500+ QSO's to LoTW from a contest for example, by the end it really slows down. And if importing 1000+ QSO's from an ADIF file, by the end, things are really bogged down. Again, not that big of a deal. This slowdown happens on a very fast 8700K Intel setup with a very fast M.2 SSD too, so it's not really I/O dependent, or if it is, on an old setup, I suspect it would get even slower by the time the LoTW upload processing completes.

+ On the Main window's "Import QSOs" tab, is "Duplicate checking" enabled?

Thanks for this, I have never really used this DXV feature. In following your instructions, using DX Atlas as my map, I do not see anything happening on the map when I click on QTH Sunrise for today and then tomorrow.

+ That's correct. DX Atlas provides no means by which an application like DXView can specify the date and time at which the solar terminator is to be depicted; DX Atlas only provides an on-screen control that you can manually set. Thus clicking on times in DXView's Sunrise/Sunset window only updates the terminator position in DXView's World Map window.

Several ops have reported here that DXView's mechanism for computing future Gray-line openings finds no such openings between their QTH and multiple DXCC entities. While this is correct behavior, it's not an intuitive outcome.

Gray-line openings at your QTH occur during two intervals every day: around sunrise, and around sunset. During each of these intervals, you have a Gray-line opening to all other locations on the planet that are close to the solar terminator at that time, meaning that they are also experiencing either sunrise or sunset.

Because the earth is tilted on the axis about which it rotates, the position of the solar terminator at your QTH's sunrise and sunset changes every day as the earth orbits the sun. Thus your Gray-line openings change every day.

To see this,

1. make sure you've specified the location of your QTH in the QTH panel on the General tab of DXView's Configuration window

2. click the World button on DXView's Main window so that DXView's World Map is visible

3. click the Sun button on DXView's Main window. In the "DXView Sunrise/Sunset" window that appears,

3a. check the "Auto update" box at the top

3b. click the "Sun rise & set" button near the upper-left

The scrollable table at the bottom of the window should now show "QTH Sunrise" and "QTH Sunset" times for the next 30 days.

In the table, click the time shown for today's "QTH Sunrise"; the World Map window will show the location of the solar terminator at your sunrise today.

Now click the time shown for tomorrow's "QTH Sunrise"; the position of the solar terminator will shift, albeit slightly. Clicking the QTH sunrise time for each day will show the terminator position shifting slightly each day.

Now scroll to the end of the table, and click on the time for that day's sunrise. The position of the terminator will have shifted significantly relative to its position at today's sunrise.

Every day provides a slightly different set of sunrise and sunset gray-line openings! Over the course of an entire year, the position of the solar terminator at your sunrise and sunset varies greatly. The sum total of all planetary locations that fall under the solar terminator at your QTH sunrise or sunset over the course of a year are the locations with which you will have Gray-line openings.

Unfortunately, the locations with which you will have Gray-line openings over the course of a year does not include every location on the planet. To see this, use the "Solar position" panel on the Configuration window's "World Map" tab to show the position of the solar terminator at a date and time you specify. You can use the "m" buttons to add or subtract a month at a time, quickly showing the terminator's location over the course of a year. You can use the "h" buttons to add or subtract an hour at a time in order to choose a time near your sunrise or sunset. Not every location on the planet has a sunrise or sunset every day of the year; the polar regions spent part of the year in total darkness or total sunshine. Those locations that do have a sunrise and sunset every day may not ever have a sunrise or sunset that coincides with your QTH's sunrise or sunset.

Ghassan, others can give a more technical explanation, but from the view
of a typical DXer, here are some details.  The greyline is the
transition period from sunlight to darkness, or from darkness to
sunlight.  During this period, which can last for many minutes, radio
signals can more easily propagate over long distances.  This of course
makes possible short QSOs between two places that, under more typical
circumstances, would not be able to take place.  Because the earth's
axis tilts over the course of the year, the greyline shifts, within
certain limits, plus or minus 15 degrees or so East and West.

This means that at certain times of the year a propagation path between
two locations will be open when it otherwise never would be.  If you and
a rare DX location share a path, you'll have a better chance at making a
QSO.  That's why people who want to maximize their chances of getting a
particular rare station pay attention to greyline conditions.

That's an oversimplified explanation of greyline propagation.  I hope
that it helps you a bit.

Re: DXView Gray-Line

w6de
 

Do a Google search on ‘gray line propagation and there are a number of explanations from the simple to technical.  Here is the one I like best:

The "grey line" is a band around the Earth that separates daylight from darkness. Propagation along the grey line is very efficient. One major reason for this is that the D layer, which absorbs HF signals, disappears rapidly on the sunset side of the grey line, and it has not yet built upon the sunrise side.

I'm using WSJT-X with direct operation with DXLab as per:

Maybe I've overlooked it, but I'm wondering of there's a way to not spot in SpotCollector those spots of needed grids/countries that
I'm not decoding but are being worked by other stations.

+ You can't prevent such spots from being added to the Spot Database, but you can filter your view of the Spot Database to show only
entries created by an instance of WSJT-X decoding a station.

Assuming that on the General tab of WSJT-X's Settings window you have the "Station Details" panel's "My Callsign" set to N7US, and
that you have realtime award tracking for grid squares and DXCC entities appropriately configured on the Award tab of DXKeeper's
Configuration window setup, then this SQL expression will limit the Spot Database Display to needed stations decoded by WSJT-X:

Re: DXView Gray-Line

Larry Knain
 

On 40, 80, and 160 you can get propagation along the "gray line" - the line between day and night. If you can, see ON4UN's book on Low Band DX'ing.

From the East coast of the US to the West coast of Australia about the only time we can make QSOs on 160 is along the gray line and it runs more or less about 15 minutes centered on our sunrise (US).

+ That's correct, Rick. There are many locations on the planet to which there will never be a gray-line path from your QTH.

+ To see this, use the "Solar position" panel on the "World Map" tab of DXView's Configuration window to see where the terminator lies during each month of the year, fine-tuning the terminator position by adjusting the hour.

+ It would be an interesting exercise to develop an application that checks every grid square for the existence of gray-line paths from your QTH at some time during the year, identifying those grid squares from which there is never a gray-line opening.
