To all.
This is a long message, apologies, hope it doesn't break any forum rules....
but it's full of worthwhile information on this topic.
===========
This message will explain how you can create your own "DF plotting" website,
just like the one shown in my YouTube video... and run it on your own PC...
for free.
( it has a TEST mode that can run without any DF hardware attached... that's
what is shown in the video )
===========
For those who haven't seen the YouTube video, it is HERE :
https://www.youtube.com/watch?v=GdJqKNpWG5c
That video has now received 60 views, and 45 of those were done after I
announced it here on this forum.
The DF display shown in that video was generated by a VB6 program, running
here on my home PC. In fact, it's still running... right now.
It could form the foundation of an internet-linked base station DF network,
with one program installed and running at each DF site.
===========
The VB6 program in that video ( called DoppSite ) is FREE. and it's
available NOW, on my website.
Information about it is HERE :
http://www.silcom.com/~pelican2/PicoDopp/PICODOPP.htm#DS
http://www.silcom.com/~pelican2/PicoDopp/DD_MORE.html
NOTES for its installation and use on a PC ( NOTES = MsWord document, 1.1
Mb ) ) can be downloaded HERE :
http://www.silcom.com/~pelican2/PicoDopp/DoppSite_Notes.doc
============
The actual DoppSite program is available as a ( 1.5 Mb ) zipped download,
HERE :
http://www.silcom.com/~pelican2/PicoDopp/DoppSite_Demo_Install.zip
The program installs easily and simply... an installation "wizard" program
is provided, to automate the process.
Some error message will probably appear the first time the ( installed )
program runs, because it needs configuration info the be installed.
( Station LAT/LONG, COM port number, NETWORK port number... stuff like that
)
=============
Some of the links on that website are dead or out of date, but the ones
shown in this forum message are valid.
Some of the information also is out of date, the LIVE DEMO station is
dead... but more than 90% of the info is still valid.
The displayed DF bearing line is 25 miles long, but the website says it is
only 1 mile.... the website is wrong, but I never fixed it.
=============
This program accepts an RS232 input of Agrello Doppler DF messages at 4800
band, and generates a website that can drive a ( remote, internet-linked )
GoogleEarth display, as shown in the YouTube video.
It runs on a regular Windows PC and needs an RS232 COM port ( or equivalent
) and an Ethernet ( or equivalent ) network connection.
( The PC must be located at the DF site, to get the DF bearings from the
RDF... but in TEST mode, it can be anywhere )
The network connection must go to an internet Gateway computer with one
port ( at the PCs address ) configured for PORT FORWARDING, in the Gateway
computer.
=============
Some people might want to see this program... running... before they try it
themselves... and I don't mean a YouTube video, I mean the "real deal", on
a "live" GoogleEarth display.
If you want to see the program that is running ( in TEST mode ) on my own
computer here in California ( Santa Maria ) you can get a GoogleEarth
NETWORK LINK file from my website, HERE :
http://www.silcom.com/~pelican2/PublicIP.kmz
This file must be installed in GoogleEarth, it gives the GE display all the
info it needs to find and display my ( California ) station on your GE
screens. ( and it refreshes every 3 seconds )
Save this file somewhere easy to find ( desktop ? ) it will be a small KMZ
file, about 300 bytes, named "PublicIP.kmz"
Find the file on your computer, double-click it, GoogleEarth will start up
and you will see it has "installed itself" in the GE left sidebar PLACES /
TEMPORARY PLACES box.
Double click on the name in the GE sidebar box, ( PublicIP.kmz ) and GE will
"fly to" the DF station ( at my residence ) in California, near Santa Maria.
You will see a red bearing line, 25 miles long, rotating clockwise at 1 RPM,
moving every 3 seconds. ( it looks just like the video... but this is
LIVE... )
