[Alan Kung]

Hi Charles,


We will analyze this phenomenon to try to find out the cause of the failure.


Thank you!

Here is a recording of the east coast North America pass around 1550z.  The satellite transponder shuts off after about 2 seconds of being on, and comes back on again after 5 seconds. http://n3crt.net/sat_recordings/2020-06-20_1550_CAS-6.mp3




Thanks,

Hi
Listened here with a max of 7 degrees now. Transponder ON
But, with many cuts.
Two or 3 words goes OFF and returns.
I heard some HAM on CQ CW.
Unable to identify. ON ~ OFF

At present, only the carriers are transmitted on the two frequencies, the linear transponder has been put into operation. We will then try to diagnose and then determine whether the CW and telemetry data stream transmission can be recovered.
