Hi Robert,
Can you tell me the settings you have selected for
Mode-C/S
- Separation
- Detect
- Select
Initial findings, PAW started running at 10:13:08 (Zulu Time)
so 1:15:00 into flight would be about 11:28:00
at 11:32:01 I see the following
$PFLAA,3,1500,,741,1,,,,,,0*72
this indicates an A/C 741 metres above - 2431 ft, in SD this should have been shown as 2.4
then at 11:32:49
$PFLAA,3,1500,,-1,1,,,,,,0*5C
this indicates an A/C 1 metre below !
This repeats for 10 seconds, very close, or at your height
$PFLAA,3,1500,,-1,1,,,,,,0*5C
$PFLAA,3,1500,,-2,1,,,,,,0*5F
$PFLAA,3,1500,,-3,1,,,,,,0*5E
$PFLAA,3,1500,,-4,1,,,,,,0*59
$PFLAA,3,1500,,-3,1,,,,,,0*5E
$PFLAA,3,1500,,-2,1,,,,,,0*5F
$PFLAA,3,1500,,0,1,,,,,,0*70
$PFLAA,3,1500,,1,1,,,,,,0*71
$PFLAA,3,1500,,2,1,,,,,,0*72
$PFLAA,3,1500,,5,1,,,,,,0*75
this should have shown in SD as 0.0
more importantly, it sounds like you are receiving your own transponder, which is why I wanted the settings above, this repeats a few times whilst I presume your transponder is interrogated.
I then see an A/C at 11:42:09
$PFLAA,3,1500,,-355,1,,,,,,0*5E
1100ft below
I then see an A/C at 12:03:02
$PFLAA,1,4500,,283,1,,,,,,0*7E
928ft above
There are lots more contacts, but this looks like the period you were referring to.
Thx
Lee
