[aprssig] Re: [Xastir] Investigation into TELEM packets (XASTIR)

What has got me mystifed is that the normal looking packets get through from PCSAT2, just the TELEM fails ???

Example

This one gates

27/09/05 10:16:37 PCSAT2>BEACON,SGATE,WIDE,qAo,W7KKE-13:USNA/ARISS Prototype CommSat. PCSAT2(A)

These will not gate (from XASTIR)

27/09/05 10:16:10 PCSAT2>BEACON,SGATE,WIDE,qAo,W7KKE-13:T#742,149,151,001,001,079,11111110,0001,1
27/09/05 10:16:20 PCSAT2>BEACON,SGATE,WIDE,qAo,W7KKE-13:T#743,171,181,161,153,156,11111110,0010,1
27/09/05 10:16:30 PCSAT2>BEACON,SGATE,WIDE,qAo,W7KKE-13:T#744,158,103,019,122,213,11111110,0011,1
27/09/05 10:16:42 PCSAT2>BEACON,SGATE,WIDE,qAo,W7KKE-13:T#745,024,027,236,015,016,11111110,0000,1
27/09/05 10:16:50 PCSAT2>BEACON,SGATE,WIDE,qAo,W7KKE-13:T#746,149,151,001,000,079,11111110,0001,1

So why does the APRS - IS stream not like XASTIR TELEM igates ?

Can someone send me some UI-VIEW IGATED data ?

Normal RF packets gate fine as well.

I will get some more data
