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".

respectively)
11.7GHz, 12GHz, 13GHz
vs.
10.7-11.7GHz, 11.7GHz-12.75GHz
vs.
10.7GHz-12,75GHz, 14,0-14,5GHz.
