I haven't look closely at this, but do we know EiRP from this bird?

I'd most likely use an MTI flat panel 10 GHz antenna I have to track it 
initially depending on the link budget. The flat panel has 25 dBi gain 
so about 8 degree beam width. It could make tracking easier...

I'm unsure what I'll use for a receiver yet. I do have a modified 
European LNB that uses 10 MHz GPS lock. SDR IF's are not a problem. I 
probably would use my ADALM-Pluto as that can be GPS locked as well. 
Then no guessing on frequency. We'll see.

If the X-band transmitter is on over this part of the planet I'll be using a 68 x 61 cm offset feed dish and initially just let the satellite fly through the beam. If I see a decent signal I'll get serious about trying to track it.
