- Raspberry Pi Model B (or B+) with a MicroSD Card $35-40
- An RTL-SDR dongle:

// It's ugly but should get the job done | |

# Generate a new pgp key: (better to use gpg2 instead of gpg in all below commands) | |
gpg --gen-key | |
# maybe you need some random work in your OS to generate a key. so run this command: `find ./* /home/username -type d | xargs grep some_random_string > /dev/null` | |
# check current keys: | |
gpg --list-secret-keys --keyid-format LONG | |
# See your gpg public key: | |
gpg --armor --export YOUR_KEY_ID | |
# YOUR_KEY_ID is the hash in front of `sec` in previous command. (for example sec 4096R/234FAA343232333 => key id is: 234FAA343232333) |

This is how I hand-track polar-orbiting weather satellites using an old equatorial mount telescope tripod and a 1.7 GHz grid dish. This may not be the best way to do it, and other ideas are welcome!
If you're unfamiliar with HRPT reception, this is not the right place to learn about it. Head over to https://sgcderek.github.io/blog/beginner-hrpt-guide.html for that. This write-up only focuses on hand-tracking to record a baseband.
The crux of the "tracking" design is the equatorial mount. These are not cheap to buy new, it's destructive to mount a dish to it, and the mount is not used the way it's designed - but for my needs, it works! I had an old one from the early 1990s lying around, so it was convenient and essentially free. Of course, you can use another mount - but you'll need to ask for someone else's opinion on how that works since equatorial is all I know 😄.
