People have been asking me to review the Discovery Dish (

https://www.krakenrf.com/The Discovery Dish is a simple, lightweight satellite antenna that can use various feeds for different radio bands. I tested out L-band (1.7GHz, S-band (2.2GHz, Inmarsat (1.5GHz) and H1 (1.4GHZ). I found the antenna to work really well for L-band satellites like NOAA and Meteor, and OK for weaker satellites like Metop. It also works great for geostationary GOES satellites. I should note that this might not work for some European geostationary satellites like Elektro or GOES-15, although I haven't tried those myself.
The S-band feed also works fairly well, and could probably be improved with a motorized tracking mount or additional amplifier. It might have some potential uses for Wifi as well.
The Inmarsat feed is great for looking at Std-C, Aero, and COSPAS-SARSAT signals, as well as GPS and Iridium stuff.
The Hydrogen Line is still a little mysterious to me, but this looks like a great starter for basic radio astronomy.
The radio astronomy software I tried can be found at
