The first screenshot is a FHSS transmission from geostationary military satellite Milstar 5 (USA 164)
It is friendly called "The waterdripper" from milsat listeners.
You are receiving only one but there are two twin satellites probably transmitting the same signal. The other one is Milstar 1 (USA 99) 37KHz higher in frequency.
