Thank you, so the “–ot hex” is really everything that is coming from the receiver.

Especially when you can build your own non-restricted receiver for about $50.

Do you know if it is also possible to get the DF00 and DF16 from the SBS1? Best regards Helge. Hi Piotr,

Best regards

I can't tell at this point whether it's the 0deg crossing issue or not. The algorithm itself was written according to ICAO docs, I believe they have taken that into account, but I must have left a bug. Waiting for a recording now :) Piotr Thanks, I have replied to you by email. I can’t tell at this point whether it’s the 0deg crossing issue or not.

BTW - I'm located in NW. England so would expect to see longitudes perhaps from 1Deg East to 4Deg West. Perhaps getting contacts on "both" sides of 0Deg meridian is the issue? Colin @Piotr

The new algorithm does not need to know the receivers location, but as I said it was tested exclusively in Europe so I didn't really have a chance to play with Western Hemisphere :) Hi Colin,

Just what I've been looking for. Is there some correction / datum change to the output longitude based on the receiver location? As is it is, it doesn't look correct. Almost looks like (100.0 - lon) would be more like what I'd expect here. Regards Colin Great work! Just what I’ve been looking for.

Yes, there are two more fields IAS and TAS, but they are not present very often. I will provide more detailed information when I have some more time. btw. the theme was not created by me, it's "monochrome" by "mono-labs". I think I'll have to change it again as it uses too space to display useless information. Hi Helge,

Just one thing: when I type "file sbs1xxx_linux_20100203-2254.tar.bz" it says: "gzip compressed data, from Unix, last modified: Wed Feb 3 22:54:51 2010" Your file is neither bzip compressed nor tarred, but apart from that, it works great!!! Thank you very much. BTW: Did you change the TCP output? I see here 17 fields instead of the former 15. It seems that there are two additional fields between "Ground Speed" and "On Ground Flag". I also saw many undocumented options when I opened the executable with a text editor. Maybe you could give a short explanation of the command line options. Helge. Hi Piotr,

The reason is very simple.. it's all about the money and no apparent need for Mac or Linux version. Most of aviation enthusiasts use Windows anyway, so why bother? The only solution would be to use portable graphics libraries like Qt, SDL or OpenGL. About the scanner thing, it's not that simple and there is no way you could feed this data directly into the mic-in of your computer. Just check the ModeS specification and your sound card sampling rate + scanners are generally focused on receiving audio and not digital transmission, it's not acars.
