Good technical dectription. Yes.  I find it to be good for the 18-24yr old level of physics, electronics and computer communications interested person.  The beamfrming and phased array antennas are explained in detail, with persuasive animated graphics and syntethic voice.  There are some pubs (adverts) too. For frequencies: it says 12GHz at the beginnning, later it says it transmits at 13 GHz  and receives at 11.7GHz. (remark two earlier posts on this list say "10.7–11.7 GHz (the lower band) and 11.7–12.75 GHz (the upper band)" and "Receive (space-to-Earth) 10,70 GHz to 12,75 GHz, Transmit (Earth-to-space) 14,0 GHz to 14,50 GHz". https://radionavlab.ae.utexas.edu/wp-content/uploads/2023/01/starlink_structure.pdf and https://www.etsi.org/deliver/etsi_en/303900_303999/303981/01.02.00_30/en_303981v010200v.pdf respectively) 11.7GHz, 12GHz, 13GHz vs. 10.7-11.7GHz, 11.7GHz-12.75GHz vs. 10.7GHz-12,75GHz, 14,0-14,5GHz. > > Hope I posted this correctly!
