Of course you will hear the satellites, if you have a decent antenna first of all
Speaking about the cheap USB DVB-t dongle, one should be aware of the limitations that this kind of equipment have. If you accept the dynamic range, NF, MDS, saturation point figures already known then it is much easier to predict and expect the results of mentioned setup.
Of course, somebody using the Flex radio or Perseus will said that the DVB-t SDR is junk, but also somebody using Harris military SDR radio 0-500Mhz can say same for the Flex radio or Perseus. On the other side the Perseus owner will be still proud on his SDR no matter what Harris SDR owner said on that.
The same goes for the cheap DVB-t SDR dongle.
I am aware of all limitations, but I still have a lot of fun using this 20$ dongle with or without HF upconverter, attenuator, LNA, filters etc. It is great and most of all affordable peace of radio that can be entry for the young and most of all old hams in the world of SDR.
I sell a lot of upconverters and surprisingly mostly to older hams or the hams that a coming back to hobby after a long pause. They are all interested to try this new trend, SDR and for sure this is the easiest and cheap way.
P.S. If you look for the satellites i suggest a good LNA (AD6IW have the nice LNA for all bands) and mounted close to the antenna / far from the USB dongle.
Simple notch filter made of simple L/4 section of coax cut for the 100MHz broadcast band can reduce the noise a lot and make the satellite reception more pleasant. At he same time this noch filter will kill some signals also in the TV band (200, 400, 800 MHz)
