This is a contuation of sorts o the issues described in my other topic here.

I've been working on reading the raw data from the SBS-3. According to th documentation, this can be on by opening a TCP socket on port 30006.

I've been doing this so far using aan application written by someone else, but it's' giving me some results I don't understand - namely, multiple airborne position reports from the same plane appear to come in at te same tme, but when looking at the Basestation recording they're separated by one or more seconds. I'd like to read the data myself to cross-check the application. Is there some way of viewing the data incoming on the socket using only built-in Windows tools?

After comparing the raw data results to the Basestation record log, it seems that Basestation is passing on the data points in abunch approximately every 17 seconds (I noticed that if I look at all the points which came to the raw data with a given timestamp, in the Basestation record they're updated every second or so and the timestamp of the last of those points in the basestation log is the same as the raw data timestamp).

After rereading the documentation, I tried to connect to the SBS-3 using the Ethernet port and using our application to read the data from port 10001. It works, but again, I'm getting a bunch of data points together at the same time. Has anyone had any success reading this data? I tried using telnet, but the data appears encrypted.

I also tried using Borisware, but I can't get it to work. I'm not sure if I'm doing something wrong, or if the problem is that I'm using an SBS-3, Basestation .184 and/or Windows 7. I'll try using ethernetovich tomorrow.

You shouldn't need to use Ethernetovich.

PlanePlotter uses the raw data from the SBS-3.  I would have thought 17 seconds is a rather long gap between messages?

You can also connect direct to raw data on port 10001 without basestation if you are connected by ethernet

The packets you will be seeing are the audio packets so turn of the radio otherwise you will be carrying some unnecessary bandwidth
