Hello,
In this discussion we could put all of us our observations and report about tracking HamTV blank transmission.
Freq = 2422 MHz - SR1300 - using 1m20 dish, Kuhne down converter and TT S2-1600
Today I chose 3 passes over France, I give local time ( = UTC+1):
==> 9h33 max elevation : 50.6° at 9h36
I have well received and recorded the black video during about 4 mn from 9h34 to 9h38 but forgot to click the record data and record TS buttons before this pass.( I was too much excited...)
so I started to record 1 sec after AOS
LOS was made when ISS was at a distance more than 1000 km
the tiouneData give this result:
In the top of the graphic, the "TS OK" line show when we receive good TS : it is green, and red when not. That show quicly the result of the pass
little vertical red line in the big graphic show Wifi interferences that make lost 1 packet (188 bytes).
the TiouneMonitor could be observed:
==> 11h11 max elevation 32.9°
I received and decode the video but with some cut in the signal due to Wifi interferences in a lower signal.
the tiouneMonitor show that at right of the graphic . ( video is OK at a MER> about 5dB)
==> 12h48 max elevation 63.5°
I started to receive good video at 12h48:56 and stop to receive at 12h53:27 so during about 4mn30sec
but in the middle of the pass, when the dish was high, it turned suddenly by south, and the pass was by North! so I lost some time to recover the video.
This is a bug in the tracking software.
When I lost the video, ISS was at 1400 km and I continue to receive some burst of video until 1500 km
the tiounemonitor:
That 's all for today.
