Regarding Observation 13644046 …
I assume the signal blob in the middle is real signal but what the bright yellow streak down the left side. I see the same yellow signal on a LOT of 2.2Ghz Observations
oot: the satellite name is funny. flying laptop. 
This is a terrestrial signal/noise. You can say that as it follows the doppler correction that is done to keep the satellite signal in a straight line in the middle.
Below with the red line you can see where the signal is expected using the observation’s TLE set and with the purple what path a terrestrial signal in the same center frequency would follow. The signal at the left is in parallel with the purple line, so it is something terrestrial.
Here is the same analysis moved -200KHz, where you can see that the purple line fits the yellow line:
Not very familiar but my guess is that this may be the SDR DC offset rather than an external terrestrial transmission. But I let other to verify that.

As Fredy suggests, this is a local signal inside the HackRF , for which I applied the 200 kHz lO offset in the settings cause some obs happened to show that in the center of the observation. I did run the hackrf in SDRPP without antenna and there are some strong ‘carriers’ inside the S band, harmonics of xtal oscillators go up multiple odd times.

Thank for everyones comment - As as begin to move into doing more S-Band - I am trying to figure out how to get rid of that nuisance. BPF don’t think will work.
Bandpassfilter (which is inline with my S-band stations 1433 and 3442) helps with local mobile phone provider suppression but indeed not for this problem. A good start would be to run the antenne / sdr combination in some SDRPP, SDRsharp, sdrconsole or what’s around software to get familiair with the gain settings required, and to see the local ‘birdies’ when tuning around the band.
1433 has RHCP, 5 turns, directly into bandpass, and into preamp, running 8 meters of aircell 7 , into another preamp which feedst my 1 in 2 out splitter, feeding 1433 ‘s hackrf and my strf pluto with the same signal.
3442 has been running 2 turns LHCP in 40 cm offset dish , 4 meters (RG316 ? which gives about 5 dB loss I realise now…) into the bandpassfilter, preamp, and 1 in 2 out splitter (Z-comm ) to feed station 3442 and a local receiver (ICom)
I might replace the RG316 by Aircell 7 this weekend if the hole in the roof allows the 7 mm cable to pass
I had a spare 4 m Aircell 7 running up the roof, ending in SMA connector so now I replaced the 3 mm coax by aircell 7 which should have about 1.5 dB loss instead of the 6 dB from the other cable.
Scheduled another 24 hours on both the stations to compare.
