Regarding Observation 12858633
There seems to be something wrong with the latest TLE. The previous TLE showed 0° elevation for the pass, with the current TLE it was suddenly 46°. The absence of any signal is an indication, that the previous TLE were correct.
In addition the scheduling shows unexpected new passes.

The MM 0 was something I missed when creating the TLE, give these a try:

Looks oke now

Ok - thx, I will try!

We’ll try this TLE on our next pass at the SilverSat ground station, and see if we can compare to tracking on the ISS.

Command responses were very intermittent during the last SilverSat pass. It is possible that the beacon is currently off and may need to be commanded back on (We didn’t get the acknowledgement when we commanded back on. Yeah, that’s a lesson-learned). I would greatly appreciate it if anyone sees the beacon that they post it. We will be commanding again tomorrow.

During latest pass not a perfect match for TLE - a few KHz low at TCA - but no problem for CW

… and no more signal at 17:25z

This picture is dark because it was taken at night.
