Newbie help please

Are you having trouble getting Virtual Radar Server installed and running? If so then this is the place to ask about it.

Newbie help please

Post by jabawokee » Thu Jan 03, 2013 12:48 pm

Greetings
Happy new year to you all.
I am using RTL1090 and receiving good data,
on startup of VRS I get the following, "cannot start web server on port 31001" also, webserver status = offline, when I try, take online = unhandled exception caught, cannot access a disposed object, object name: system.net.listener" plus a load more info, when I click the http://127.0.0.1:31000 link VR hangs loading, any ideas please?????

Happy new year :) The port number sounds a little high, it sounds like a rebroadcast server port number. Is this a Windows installation or Linux?

If it's Windows - the port number is selected when you run the installer. It's usually best to leave it at the default of 80 unless there is other software on the machine that is using port 80. If you re-run the installer and change the port number to 80 then let me know what happens.

If it's Linux - I'm presuming you ran VRS, set up a rebroadcast server and then edited InstallationConfiguration.xml and put the rebroadcast server port number into there? The rebroadcast stuff is for retransmitting the messages from the receiver across the network whereas the port number in InstallationConfiguration.xml is the web server port number. If the rebroadcast servers start up before the web server (I can't remember offhand the order in which those two start) then they would prevent the webserver from using the port you've told it to use, only one thing can be listening to a port. If you change the InstallationConfiguration.xml port number back to 8080 (80 would be better but there's often a web server already running on Linux installations, and that would be using 80 for itself) then you should be alright once you've restarted VRS.

Hi, seems to be working ok now ta, not many ac overhead, might need a better antenna?
Cheers,

Probably, that seems to be the emerging pattern :) I've added a statistics screen to VRS that should help diagnose the proportion of good messages to corrupt messages, it'll be in the next release. If you want to try a preview version to see what kind of %age of corrupt messages you're getting then I can send you a link to it, although it may have bugs.

Hi
The link would be great if you don't mind, this is what RTL1090 is receiving at the moment, is it my setup or is the antenna naff??? I presume that the good data is the ones with the most data in them.

Mode-S transmissions are either 7 or 14 bytes long so all of the lines are potentially correct. The number in square brackets is a twist on the AVR standard that I've not seen before but VRS won't care about those, it'll just ignore them. Given that the numbers in square brackets seem a bit random but fairly consistent I'm guessing it's probably the signal strength.

All of the messages have a checksum on them, but only some of the checksums can be reliably tested. The latest version shows the proportion of messages with a reliably testable checksum that are good. I'll do an installer for it over the weekend and PM you a link to a preview version, but my guess is that you'll probably want to buy or build a better antenna.

Hello Jabawokee,
Strange, where did you get this data set? So it is only displayed in the program window for information. The value in square brackets - the signal level. It is defined in program by average preamble signals because RTL1090 ​​works as receiver BEAST in its binary format. VRS works with it without problems.
But, if you want to get strict text AVR, just add the command line RTL1090 "/avr" and outputs data at TCP port in AVR format instead of Beast binary format.
Meanwhile, my proposals to add in VRS already existing information from the receiver (or from feed) about signal level usually remain unnoticed ;). But specialized 1090MHz antenna you need in any case.

Not unnoticed, it's on the list :) I put it on the list when you emailed me about it back in September. I don't have a lot of time at the moment so I'm trying to stick to small changes. The signal level isn't a big change to the code but it'll involve a bit of work on the unit tests, and because only some receivers expose it I'll need to add code to the server and the website to suppress its display for people that don't have it. It'll get done, just not right away.
