I’ve had my digipeater/iGate running on a Pi 3 with RTLSDR dongle for several days and I’m pleased with the result. It is definitely filling a coverage gap for me while running errands within a few miles of the house. It is also helps fill in coverage for other hams. Even a group of hams headed to Huntsville’s Hamfest hit mine as they passed through. Overall a cheap and useful project.
