Crowd Supply is hosting Teardown Session 38 on Thursday 3- November at Noon PST time which will feature the Discovery Dish. Join us for this livestream where I will be talking about and showing the Discovery Dish prototype.
Discovery Dish is currently being crowd funded over on Crowd Supply. It is designed to be an easy entry to the world of L-band weather satellites, hydrogen line radio astronomy, and Inmarsat reception. The Discovery Dish aims to be the start of an ecosystem of hardware designed to get users set up with satellite reception, including a planned companion light-duty antenna rotator.

Over on his YouTube channel, "saveitforparts" has uploaded a video showing how he's modified an old wireless networking dish for L-band HRPT satellite reception. L-band satellites that transmit HRPT are polar orbiting, meaning that some sort of tracking solution is required to point the satellite dish at the sky as the satellite passes over. However, lacking any sort of motorized solution, saveitforparts simply removes the dish mount so that the dish can be manually held and tracked.
He notes that he uses the paid version of the Stellarium app for augmented reality tracking of the satellite. In the past there was a great app called "Satellite AR" which did this for free, however within the past few years it has unfortunately been removed from the Google Play store.
The modifications to the dish involve removing the feed from the satellite and installing a custom built helical feed. He also uses a small handheld PC with RTL-SDR on the rear. However in the end the handheld PC turns out to be problematic so he switches to a laptop.
The dish used in saveitforpart's project is quite similar to our upcoming Discovery Dish crowd funding project, so please check that out if you are interested.
