Great stuff, imagine doing radio astronomy with this more capable RFSoC SDR platform with 50% discount for academics at around USD2K [1]. It also has free textbook to go with it [2].

Anybody has experience using rasdr4? What is it capable of?
Are there Rydberg antenna SDRs for radio astronomy?
What sensitivity (?) is necessary to navigate by the EMF of stars?
FWIU this is called astronometry? There's probably a better word than "astral"?:

> How many astral signals does a receiver need to fix to determine to infer the current time, given geometrically-impossible triangulation and trilateration solutions given the known geometry of the cosmos and the spherical shape of the earth?
