Not sure if this is the correct forum, move the post if necessary.

RTL1090 Beta 2, table screen. Anyone can explain about meanings of g*456^ column?

G: on ground (no doubt).
*: position available or timed out (no doubt). What about even or odd CPR position data? What do they mean?
4, 5, 6: EHS reply....   An explanation would be welcome.
^: DO260A/B format indicators...  A brief explanation please?

Thank you !!

Look down the page and you will see "RTL1090 Installation and Operations Manual"

Hopefully this will answer all your questions

Not at all. I know the document but not what those items do really mean.

The questions are:

1.- What is an even (or odd) CPR position data?
2.- What is a 4 (or 5, or 6) EHS reply?
3.- What is a DO260A/B format indicator, and differences between them.

Just to know what RTL1090 is "saying" to me.

Although Andy from Jetvision does visit this forum, you may get a quicker answer if you post the question on the RTL1090 Yahoo Group:

Thanks Anmer, I find Yahoo Groups not too much user-friendly, but I'll try.

I have another questin. How many RTl1090 can i use as a Hub?
On this time i use 3 DVB-T Dongel to increase my Coverage in the Future i will take +10 Directional Antenna to get the Max Signal i get.
And i know some People how life next to an Airport.
What did RTL1090 do when 5x Dongel get the Same Aircraft?
THX

It sounds like you want to chain the dongles together so that you get all the data to display on one pc screen? I think the rtl1090 software uses the strongest signal when it looks at data from multiple dongles, although I could be wrong on that one.

When I chained my 2 dongles together to increase coverage I used this tutorial, which worked flawlessly.
