The Outernet Dreamcatcher is a single board PC with a built in RTL-SDR. It has a TCXO and two SMA ports, one being amplified and filtered for L-band applications and the other being a regular port for all other applications.
With built in computing hardware the Dreamcatcher can be used as a standalone unit for various applications. As the Dreamcatcher is now on sale we've decided to create a brief tutorial that shows how to set one up as a cheap ADS-B aircraft radar receiver, and also how to set it up as a PiAware feeder. PiAware is software that allows you to feed FlightAware.com which is an ADS-B aggregatpr.
Any simple SMA antenna can be used, like our Dipole kit, an old RTL-SDR whip antenna, or even a short piece of wire.
We also have a previous review of the Dreamcatcher available here. In the past the main problem with the $59 USD Dreamcatcher was that you could get a more powerful Raspberry Pi 3 and RTL-SDR dongle for a similar price. But now at the sale price of $39 USD the Dreamcatcher is definitely a great deal.
Note that we'd recommend NOT purchasing the Dreamcatcher specifically for the Outernet data signal as we're unsure exactly how long that signal will continue to be broadcasting for.
What follows below is a tutorial that shows how to set up a Dreamcatcher. The tutorial installs dump1090 at the same time, but afterwards could be used for a number of other applications.
