I found that many USB cables do NOT have the SHIELD connected to both ends, and my com port adapter had the same issue. Once I used all cables with shield continutiy and jumpered over from the usb to the com side on the adapter, the intermittent problems with "loss of usb" went away.

You are all right.
Or maybe not entirely so. The government is elected as far as i know. So
there are two options: either there is no democracy in that country and the
citizens chickened out to do something, or the citizens of that country
agree with their government.
Maybe you don't know, but a vast number of Russian hams are in fact ex
military personnel (or not so ex) and also connected with Russian secret
services.
So, each one should decide for himself to make contacts with Russian hams
or don't.
I personally decided to close the qso with the free message ".callsign. NO

locked Re: Very interesting use of WSPR information to solve a long standing mystery #reception #WSPR #bearing

Alan <g8lco1@...>
 

Hi Alan,

The Doppler shift depends on the relative velocity and the angles and is also proportional to the frequency. The shifts I gave were the values that are typical on 20m  for aircraft landing or taking off from an Airport. The typical approach speed of an airliner is around 150Kn. If you look at the dupes record from WSPR.LIVE  then click on the highlighted signal the software will show all of the data from that spotter. Shifts of 2-20Hz are probably aircraft reflections. Such  a search shows ALL of the spots recorded.  Of all spotters in the World there is only one station that consistently has many Doppler spots,  ON3URE  close to to Brussels Airport and underneath some very busy lanes.

Higher shifts would be produced by  aircraft at cruising altitude but the signal level is much smaller because the aircraft are much further away. Aircraft reflections from WSPR are inevitably weak, the very small WSPR signal induces a current into the aircraft structure which is then re-radiated in all directions, a further reduction of a weak signal which sends high reflections below WSPR detectability. The normal spotter SNR range at HF is around  +20 to -30 dB so the very maximum loss could be -50dB, unfortunately the additional loss from  aircraft scatter at 27,000 - 40,000 ft exceeds  the 50dB additional loss, the Doppler shifted spots can be linked to Flight Radar 24 plots of aircraft either landing or taking off at a local airport but 1000's of Km are not possible, 20Km is the very most I could find in 40,000 records but the majority of Doppler shifted signals were at shorter distances. There are thousands of Aircraft in flight at any time and many thousands of WSPR signals present too yet the Doppler shifted spots in the record are confined to a handful  of spots, further evidence of the inability of WSPR to detect Aircraft at altitude.

OTHR is not simple or cheap. Many Nations have tried and failed , it is a very difficult processing problem. Many different systems, antennas and processes have been tried.  The recipe is simple, 1-40MW ERP,  100-500 element arrays for TX and separate RX array with as much computing power as you can get. You need to track the state of the ionosphere continuously ( the underside is not flat at all) and try to process out groundclutter which can be 80dB above the signal you are trying to track for just one hop.

If they could have done it with 5W TX power and dipoles they would have! But you would not choose a 2 min cycle to track a fast jet that has moved 30 miles, even an Airliner can move 20 miles in 2 mins.

Godfrey can only lift data from the WSPR database that is the only data available. The civilian flight plotting services all depend on ADSB which is a record of signals received from aircraft transponders ( secondary Radar) but the MH370 pilot turned off the transponder after the first waypoint so there is NO record of where MH370 went subsequently apart from the Inmarsat "Arcs", single arcs of position at roughly hour intervals.

As far as I  am aware Godfrey used the known position of a search aircraft to test his theory. He selected WSPR records that matched the known position of an aircraft. This is a false  many-one mapping, you are not finding an aircraft position but connecting noise to a point in space and time. This is similar to Ley Lines where people joined up  a few mapped antiquities with lines, this does not prove that churches, hill forts and settlements built over many thousands of years were deliberately built in lines but that the human brain has a very strong desire to make connections where there may be none. This feeds into our love of detective stories and concealed conspiracies with the opportunity to make millions out of inventing fantasy.

A problem with WSPR is that it is an indeterminate receiver, the SNR is the ratio of the averaged received signal to the local noise level in the RX bandwidth. So variable levels of QRM, QRN and other transmitters randomly keying up and down all modulate the SNR number in random ways. SNR is not an absolute number but a relative-to-the-noise ratio, those are the SNR numbers in the database, the SNR is subject to random variations that are not separable. A good example of the variation is the Noise plots produced by some KiwiSDR software which measures the noise levels between WSPR transmissions. These vary considerably over a day, vary every day and are different for every spotter.

If anyone has looked at the links in my last post they would have seen two independent evidential details that support the Christmas Island destination, the Cocos Island seismic event and the Flaperon Barnacles.   The Flaperon from MH370's wing had trailing edge damage consistent with a ditching but there were also Barnacles that could only grow while the flapperon was in Tropical waters not in the colder waters of Godfrey's suggested end point.

It seems obvious that Pilots fly to land safely. There have been a very few pilot suicides, they have chosen to fly into mountains or the sea at very high speeds. When this happens the aircraft shatters into very many parts many of which float, the debris field is vast and very easy to find. It is far more likely that the MH370 flight was towards an airfield  but that there was a ditching in the sea because the fuel ran out due to long periods of fuel draining low altitude flight.

Exhaust trails. They are condensation trails when the exhaust gasses meet the very cold air at altitude. They are similar to Clouds and are just as invisible to HF radio. Only visible at high microwave frequencies where water vapour resonances occur.

VHF reflections. This is a very well known observation especially if the antenna is positioned to null out direct signals to the illuminating transmitter or if the receiver is  deep down in a Valley.  Here the illumination is often very bright and the TX is close.  This was first set up by Arnold Wilkins near Daventry UK in February 1935. He used two dipoles and a goniometer to almost exactly null out a signal from a very powerful local HF broadcast station. When an aircraft flew nearby a fluctuating signal was received demonstrating the aircraft echo was detectable. The max range was around 12Km with many KW ERP. The experiment was a vital initial step towards the development of Radar in the UK.

However the MH370 affair concerns HF signals with very weak illumination at 1,000Km ++ ranges and a reflected much smaller signal that is said is detectable 1,000's of Km further away. Chalk and Cheese!

Williams, G (af8c)
 

The following  .BAT batch file will search the ALL.TXT file for any single token (not containing  only a SPACE character nor a leading HYPHEN character) in the folder %LOCALAPPDATA%\WSJT-X\  . All text lines containing the token will be listed. Command line 5 in this batch file can be easily edited to search for anything else an any text file, such as a LOG or ADI file.  By creating a desktop icon for it, you can run it even during operation of FT8 etc.  This batch file can be located in the DOCUMENTS folder for example.  With some work you can add lines to search for two tokens at a time, etc.

You do not need LTF or NOTEPAD++ to use this.  IF you wish to save the contents of the result shown in the COMMAND PROMPT window, merely right click on the top bar of the window, select EDIT, and proceed to select the text you want to save.  Then restart the EDIT and click COPY to save the text to the windows clipboard.  From there you can paste the clipboard contents into a regular text editor, paste it into an email, save it in another logging program, etc.  In my use I have not seen it break anything.  It can be modified to fix any problems that I have not found.

There is no ‘automatic’ option to do as you ask.

See this thread from a couple of weeks back:

https://wsjtx.groups.io/g/main/message/32363

You can get a 3rd party script, will need tweaking a little and away you go. The script will have the settings for GPS port and generate the UDP messages WSJT-X can then use.

Most platforms have built-in location services these days. These rely on multiple sources of data and don't necessarily require GPS.

I'd like to request that:

a) Auto Grid be set on by default, wherever any location service exists;
b) Auto Grid use platform-based location services by default.

This would avoid some problems with PSKReporter spots from an incorrect grid when someone does a portable operation and forgets to set the grid.
