Regarding Observation 1737767 (among other observations), it seems Argus-02’s transmission frequency may have shifter down 10-20kHz. We are unsure as to why, but we have seen Argus-02’s pattern on this slightly lower frequency consistently. Would it be possible to add a transmitter on this frequency to see if. Argus-02 is better captured?
For context, Argus-02 transmits telemetry every 45s, which fits the pattern.
Again as the previous observation from this station the signal at the right is AZTECHSAT-1 and the one faint at left is a terrestrial one.
At the right is AZTECHSAT-1 and at the left/center the noise/terrestrial signal, again in station #6 as in the previous. Here is more obvious that the noise/signal follows the terrestrial noise line starting from -10KHz at the bottom.
I can not see any signal
Again signal at the right is AZTECHSAT-1
Again the noise/terrestrial signal on #6
The signal at the right is AZTECHSAT-1
Signal at right is AZTECHSAT-1. The other horizontal lines are noise, you can see something similar in the other observations of this station, like this one.
